 Quick Bibliography SeriesBibliographies in the Quick Bibliography Series of the
 National Agricultural Library, are intended primarily for
 current awareness, and as the title of the series implies, are
 not indepth exhaustive bibliographies on any given subject. 
 However, the citations are a substantial resource for recent
 investigations on a given topic.  They also serve the purpose
 of bringing the literature of agriculture to the interested
 user who, in many cases, could not access it by any other
 means.  The bibliographies are derived from computerized on-
 line searches of the AGRICOLA data base.  Timeliness of topic
 and evidence of extensive interest are the selection criteria.
 
 The author/searcher determines the purpose, length, and search
 strategy of the Quick Bibliography.  Information regarding
 these is available upon request from the author/searcher.
 
 Copies of this bibliography may be made or used for
 distribution without prior approval.  The inclusion or
 omission of a particular publication or citation may not be
 construed as endorsement or disapproval.

 Abstract:  Boron isotope ratios (11B/10B) for commercial
 produce ranged from a high of 4.162 +/- 0.003 for cabbage to a
 low of 4.013 +/- 0.008 for whole wheat flour. The observed
 isotope ratios for produce fall within the range reported for
 boron-containing minerals. Cucumbers and flour are 10B
 enriched; bananas, cabbage, celery, grapes, green peppers,
 lettuce, oranges, potatoes, and tomatoes are 11B enriched by
 at least 0.02; apples, broccoli, cantaloupe, and carrots are
 equal to NIST SRM-951 boric acid isotopic standard. Boron
 isotope ratios (11B/10B) were measured for broccoli and
 cabbage grown in a soilless medium, 4.018 +/- 0.016 and 4.032
 +/- 0.003, in a soilless medium with foliar-applied H3 1OBO3,
 1.848 +/- 0.009 and 1.746+/- 0.004, and in a hydroponic
 solution with H3 1OBO3 as the only boron source, 0.126 +/-
 0.012 and 0.098 +/- 0.005.

 Requirements
 
 Abstract:  Knowledge of the micronutrient requirements of
 strawberries is rather scarce. This plant species is
 considered to have low sensitivity to boron deficiency. In our
 work several aspects of B requirements of Fragaria ananassa L.
 cv. Douglas have been studied. Strawberries were grown in an
 automated greenhouse and in aerated nutrient solution with
 (+B) and with (-B) boron supply. The experiment started when
 fresh plants were transferred from the nursery to 4-litres
 pots (5 plants per pot) following the cultivation steps of a
 typical commercial production in Spain. Plant material (shoot
 and root) was sampled every two weeks after a gap of one
 month. Simulaneously, nutrient solutions were analyzed and
 renewed. B concentration in the n utrient solutions of both +B
 and -B increased during the 2-weeks period of culture. This
 increase was initially high but became smaller in successive
 periods. Boron content was higher in +B leaves than in -B
 ones. Nevertheless neither visula symptoms of B deficiency,
 nor reduction in growth in yield were observed in -B plants
 during the 4 months of the experiment. The lower boron
 concentration of young leaves in comparison with older ones
 would suggest a continuous supply of B from the root and a
 weak capacity of redistribution of the microelement via the
 phloem. In conclusion it appears that the large amount of
 boron stored mostly in the root at the beginning of the assay
 would be sufficient to cover the low B requirements of the
 strawberry plant studied.

 Abstract:  Tomato plants (Lycopersicon esculentum Mill.) of
 the F1 hybrid variety Turbo were grown in a NFT system for 22
 days. On days 16 and 20-22 inclusive of the experiment, the
 diurnal variation in nitrate (NO3), potassium (K), and water
 uptake rates were measured. Nitrate and K uptake rates were
 subject to large diurnal variation with maximum uptake rates
 occurring during the day period. Two peaks of diurnal uptake
 rates were identified, one large peak during the day period
 and a second much smaller one during the first 2-4 hours of
 the night. Under the conditions of the experiment, night
 nutrition made up 35 to 40% of the total daily uptake of K and
 NO3. Water uptake rates followed a diurnal oscillation with a
 single peak pattern. Highest rates occurred at the middle of
 the photoperiod and lowest rates were measured at night. Over
 the entire day and night cycle there was no correlation
 between the rates of water and nutrient uptake. This may be of
 importance in the fertilization of hydroponically grown plants
 since in horticultural practice nutrients and water are
 supplied together in quantities large enough to meet plant
 water demand but not nutrient requirements.

 Abstract:  An algorithm was developed to select a economically
 optimum temperature trajectory for greenhouse hydroponic
 lettuce production. Daily air temperature was selected to
 maximize he difference beween crop worth and cost to heat. To
 select an optimum temperature, crop worth was determined for a
 range of possible inside temperatures by projecting crop
 growth forward to harvest using expected values of weather
 variables based on historical weather data. After an optimum
 temperature for the day in question was selected, the status
 of the lettuce crop was updated based upon the selected
 temperature and the day's actual weather data.

 Abstract:  Results of simulations from a computer model
 developed to determine economically optimum day temperature
 for greenhouse hydroponic lettuce production are presented.
 Selected optimum air temperature is a function of many factors
 including available insolation, stage of growth of the crop,
 length of the growing period, lettuce worth, and fuel costs.
 Potential savings due to production at optimum day
 temperatures compared to standard temperatures were estimated
 based on simulation of five years of operation. Potential
 savings vary depending on fuel cost and whether the greenhouse
 is operated such that only plants of the same age are present
 or such that many age groups are present simultaneously.
 Savings varied form 10 to 30% of the heating costs.

 Abstract:  In addition to essential inorganic nutrients,
 plants may need other organic substances as they have grown in
 soil. The capacity of microorganisms to synthesize biotic
 substances in a soil has been for a long time. Of these
 substances, a B-group of vitamins (Thiamine, Nicotinic acid,
 and Pyridoxine) and amino acid (cysteine) were selected as
 good source of nutrition for the plants. Present paper shows
 the effect of the addition of a mixture of these organic
 substances and iron to the nutrient solution on the growth and
 nutrient uptake in cut-flower chrysanthemum in the nutrient
 film technique system. A mixture of these substances added to
 the basal nutrient solution had a marked effect upon the
 growth and uptake of inorganic nutrients in chrysanthemum
 plant. Leaf green color was intensified by the treatment of
 liquid fertilizer containing thiamine, iron, and cysteine. As
 a side effect, these substances gave resistance of plants to
 unfavorable conditions.

 Abstract:  Butterhead lettuce (var. Gloria) were grown in an
 evaporatively cooled glasshouse using the nutrient film
 technique (NFT). During the day all plants received a complete
 nutrient solution (EC 2 dS/m). Treatments were imposed at
 night and included: complete nutrient solution (control); tap
 water (EC 0.19 dS/m); and calcium nitrate solutions containing
 either 100 mg Ca/L (EC 0.80 dS/m), or 200 mg Ca/L (EC 1.45
 dS/m). Tipburn occurred in the control and its incidence was
 reduced by the other treatments. This effect was associated
 with an increase in the concentration of calcium in new
 leaves, except in the water treatment. The night treatments
 did not affect the fresh weight of mature lettuce. Circulation
 of either water or calcium nitrate (100 mg Ca/L) at night may,
 therefore, be a commercially acceptable means of reducing
 tipburn losses in lettuce crops grown using hydroponics.

 Abstract:  Butterhead and cos type lettuce (Lactuca sativa L.)
 .cv. "Bellona" and "Paris cos island" respectively, were grown
 in nutrient film culture, under various electrical
 conductivity levels (1.5-2.0-2.5-3.0-4.0-5.0 mS). Fresh and
 dry weights of shoots and roots were measured for their
 seasonal growth, over a period from October to May, under an
 unheated glasshouse. For both cultivars the overall effect of
 solution conductivity on shoot fresh weight, was minor.
 Increases in conductivity resulted in increased root dry
 weight.

 Abstract:  Hydroponically grown mung bean seedlings were
 inoculated with macroconidia of Fusarium solani f. sp.
 phaseoli to evaluate the effects of temperature (15, 20, 25,
 30, and 35 C) and hydrogen ion concentration (pH 3, 4, 5, 6,
 and 7) on spore attachment to roots of Vigna radiata.
 Macroconidia of F. s. phaseoli attached to second-order roots
 with root hairs in greater numbers than to those without root
 hairs or to roots of other orders. Attachment of macroconidia
 to second-order roots was greatest at 20-30 C and pH 4 but
 decreased by up to two orders of magnitude when the
 temperature of the nutrient solution was increased to 35 C or
 the pH elevated to 7. The binding reaction of macroconidia to
 roots was observed to be reversible when plants inoculated at
 25 C and pH 5 were transferred to nutrient solutions
 maintained at 35 C or pH 7. Plant fresh weights of V. radiata
 decreased with increasing inoculum density when plants were
 inoculated and maintained at 20 or 25 C but not at 30 C.
 Differences in plant fresh weights of V. radiata between
 inoculated and uninoculated plants were greatest at 20 C,
 decreased at 25 C, and were not observed at 30 C. In a
 separate experiment, plant roots were exposed to inoculum for
 24 h at 24 C and pH 4, 5, 6, or 7. The nutrient solutions of
 each treatment were then adjusted to and maintained at pH 6
 for an additional 13 days. Disease was greatest when roots
 were inoculated at pH 4 as compared to pH 5 or 6. Plants
 inoculated at pH 7 were not different from uninoculated
 plants. Differences in disease among plants inoculated at
 different hydrogen ion concentrations are explicable when
 based on the effects of hydrogen ion concentration on the
 attachment of macroconidia to root surfaces. Differences in
 disease among plants inoculated at different temperatures
 between 20 and 30 C are not explicable when based on the
 effects of temperature on spore attachment to roots or on
 growth of the pathogen. We propose that differences in disease
 among plant

 Abstract:  Sweet potato [Ipomoea batatas (L.) Lam.] is among
 eight crops selected by NASA for its Controlled Ecological
 Life Support Systems (CELSS) program. This research evaluated
 sweet potato genotypes for adaptability to hydroponic systems.
 Fourteen sweet potato genotypes were grown hydroponically
 using nutrient film technique (NFT) systems. Four vine
 cuttings from each genotype were spaced at 25 cm and grown for
 120 d using 14 NFT channels (0.15 by 0.15 by 1.2 m) supplied
 with a modified half-Hoagland nutrient solution. Genotypes
 responded differently to growth in NFT. 'Jewel' produced the
 highest mean total storage-root yield of 470 g per plant.
 Individual plant yields ranged from 767 g for 'Centennial' to
 36 g for 'Bunch'. Inverse relationships between foliage weight
 and storage-root yield were obtained with 11 genotypes. Edible
 biomass indices were comparable to those of potato (Solanum
 tuberosum L.) and lettuce (Lactuca sativa L.), and higher than
 those of wheat (Triticum aestivum L.) and soybean [Glycine max
 (L.) Merr.]. Based on their performance, Jewel, 'Carver',
 TU-52, and Centennial sweet potato appear well adapted to
 growing in NFT.

 Abstract:  We have developed a flow-through system (FTS) to
 study the effects of root restriction stress on plants grown
 in hydroponic culture. The system was designed to permit the
 use of varied culture container volumes (from 25 to 1500 cm3)
 and dimensions (2.5 to 10 cm. dia. and 5 to 20 cm h.). The
 modular FTS design is divided into two nutrient delivery
 systems, one for large-volume containers and the other for
 small-volume containers. Each plant was grown in a modified
 Hoagland solution in a separate container. Nutrient solutions
 were aerated and the pH was automatically controlled at 6.0 +/-
  0.2. This report describes the FTS and presents growth data
 for tomato plants (Lycopersicon esculentum Mill., cv. 'Better
 Bush') grown for a 57 day period. Our observations, when
 compared to the findings of a root restriction study made by
 Ruff, et al. 1987 (J. Amer. Soc. Hort. Sci. 112: 763-769),
 indicate that that similar characteristics result for the same
 tomato cultivar grown in either pot culture (soil) or
 hydroponics (FTS). The result of this test of the FTS supports
 the continued use of the system to study various physiological
 and hormonal parameters in relation to root restriction.

 Abstract:  During the 1987-1988 and 1988-89 growing season an
 experiment was conducted in a cold plastic greenhouse of our
 Institute aiming to evaluate five substrates in two vertical
 systems with respect to their suitability for growing
 strawberries. The following substrates were evaluated: a.
 perlite 100%, b. perlite 90% + peat 10%, c. perlite 80% + peat
 20%, d. pumice-stone 80% + peat 20%, e. pumice-stone 80% +
 perlite 20%. They were placed either in polyethylene tubes,
 1.70 m height and 0.15 m diameter in a vartical position, or
 in pots of polystyrene placed one above the other in a column
 1.70 m in height. In both cases, 36 plants of the strawberry
 cultivar Brighton were planted in each column in August. A
 system for recycling the nutrient solution was applied. Yield
 was collected from December until June. About 65% of the yield
 was taken until the end of April. Data obtained indicate that
 strawberries grown on substrate composed of perlite 80% + peat
 20% produced higher yield (250 gr/plant) than those gorwn on
 the other substrates. There was no difference between
 polystyrene pots and polyethylene tubes with respect to yield.

 Abstract:  The development of the hydroponic perlite culture
 system of protected crop production at the West of Scotland
 College has been based, hitherto, or coarse, 'horticultural-
 grade' expanded perlite which has 90% by volume in the range
 1-5 mm. Recent work has compared crop performance of
 glasshouse tomatoes in horticultural-grade perlite with that
 in two Sardinian plaster-grades which have much finer
 particle-size distributions, one with 90% by volume in the
 range 0.6-1.4 mm, the other 90% volume <1 mm. Cumulative
 yields of fruit were similar in each of the three grades of
 perlite to the end of Ausust in 1987 and to the end of
 September in 1988. Hence, although the air-filled porosity of
 the Sardinian plaster-grade perlite was lower than either the
 medium or horticultural-grade material, oxygen availability at
 the root surface did not limit root function.

 Abstract:  Three hydroponic systems, namely rockwool, perlite
 and NFT, are described. Factors affecting growth such as root
 temperature, water quality and aeration are discussed,
 together with management problems including sterilization
 between crops. Current sensitivity about environmental
 pollution is likely to cause some reduction in the use of
 systems that discharge nutrient solutions containing
 appreciable amounts of nitrate-nitrogen to waste.

 Abstract:  A highly specific and sensitive ELISA method was
 developed for the detection and semi-quantitative
 determination of artemisinin and its structurally related
 compounds in crude extracts of Artemisia annua. The antibodies
 were raised in rabbits using a 10-succinyldihydroartemisinin-
 BSA conjugate as immunogen. The peroxide linkage in the
 artemisinin molecule was critical in determining the antibody
 specificity. The working range of the assay was from 0.02 to
 10 ng per assay. The cross-reacting material in crude plant
 extracts was evaluated by chromatographic methods combined
 with the immunoassay method. The distribution of artemisinin
 equivalents in five-week-old A. annua plants cultivated in
 hydroponic conditions was investigated. The highest
 artemisinin equivalent content (1.12% dry wt) was found in the
 leaves of the upper parts of the plant.

 Abstract:  Dihaploid Solanum tuberosum and diploid S.
 microdontum plants were grown in soil and hydroponics under
 glasshouse and growth room conditions. A high light intensity,
 was necessary for flower induction in both species and the
 dihaploid flowered only when grown in hydroponics. Premature
 berry abscission was retarded by tuber removal and prevented
 by the addition of indole acetic acid to the nutrient
 solution. Seeds from prematurely abscised berries germinated
 poorly in soil, but germinated almost as well as those seeds
 from indole acetic acid-treated plants when placed on
 Murashige and Skoog (1962) based culture medium. The hybrid
 plants were intermediate in morphology, compared to the
 parents, possessed heterotic vigour and were male fertile.
 Germinating hybrid seeds on a colchicine-containing medium led
 to poorly growing plants with ploidy chimeras. Hybrid plant
 ploidy levels were doubled by regenerating plants from
 stem/leaf explants on the tuber disc regeneration medium of
 Jarret et al. (1980).

 Abstract:  The morphology and hydraulic conductivity of root
 systems of Gleditsia triacanthos L. var. inermis Willd. (honey
 locust) grown hydroponically in sand and solution cultures
 were compared. Total root system length was similar in the two
 cultures. However, root systems grown in solution had longer
 primary roots, fewer lateral roots and root hairs, and a
 greater distance between the tip of the primary root and the
 junction of the youngest secondary root and the primary root
 than root systems grown in sand. Hydraulic conductivities of
 root systems grown hydroponically for 21 or 35 days in sand or
 solution culture were similar. These findings show that
 different methods of hydroponic culture can affect root
 morphology without altering root resistance to water
 transport.

 Abstract:  It is possible to restrict the vegetative growth of
 early protected tomato crops, growing in the nutrient film
 technique (NFT) water culture, by supplying the nutrient
 solution intermittently instead of continuous flow.
 Intermittent flow regime given up to anthesis of the fourth
 truss, increased early yield but did not increase the final
 total yield. There was a highly significant decrease in root
 fresh weight. Also, a reduction in all intermittent treatment
 of water consumption 22%, was noticed under the intermittent
 flow. The water use efficiency calculated on the basis of
 fresh and dry weights increased under intermittent treatments.

 Abstract:  Sweetpotato [Ipomoea batatas (L.) Lam] is being
 grown with the nutrient film technique as part of the National
 Aeronautics and Space Administration's Controlled Ecological
 Life Support System (CELSS) program for long-termed manned
 space missions. Our objective was to evaluate the effects of
 two levels of photosynthetic photon flux (480 and 960
 micromoles m(-2)s(-1) PPF) and three N/K ratios (1:1.1, 1:2.4,
 and 1:3.6) on yield of sweetpotato when grown using this
 technique. Vine cuttings (15-cm length) of 'Georgia Jet' and
 T1-155 were grown in each treatment for 90 or 120 d,
 respectively, in controlled-environment growth chambers.
 Storage root growth for Georgia Jet and T1-155 increased with
 light intensity, while foliage growth decreased with high K
 levels. The number of storage roots produced by each plant
 increased with intensity only for Georgia Jet but was not
 significantly influenced by higher K levels for either
 cultivar. Light by N/K interactions were not significant. The
 level of PPF exerted a greater effect in enhancing sweetpotato
 storage root yield in nutrient film than did N/K ratio.

 Abstract:  Development of the use of perlite in horticulture
 has been carried out at the West of Scotland College over a
 period of more than ten years. Recent work in collaboration
 with The Perlite Institute, Inc. has led to the development of
 commercially applicable techniques. The outstanding features
 of the system include ease of water management and optimum
 air:water balance, because perlite substrate is initially
 sterile, chemically inert and physically stable. Simple
 irrigation design of one inlet per row of plants makes the
 system suitable for low-technology conditions which exist in
 many parts of the world.

 Abstract:  We describe the mechanical, electronic, hydraulic,
 and structural design of a nonrecirculating hydroponic system.
 The system is particularly suited to studies at very low
 nutrient concentrations, for which on-line concentration
 monitoring methods either do not exist or are costly and
 limited to monitoring relatively few individual plants.
 Solutions are mixed automatically to chosen concentrations,
 which can be set differently for every pump fed from a master
 supply of deionized water and nutrient concentrates. Pumping
 rates can be varied over a 50-fold range, up to 400 liters per
 day, which suffices to maintain a number of large, post-
 seedling plants in rapid growth at (sub)micromolar levels of N
 and P. The outflow of each pump is divided among as many as 12
 separate root chambers. In each chamber one may monitor uptake
 by individual plant roots or segments thereof, by measuring
 nutrient depletion in batch samples of solution. The system is
 constructed from nontoxic materials that do not adsorb
 nutrient ions; no transient shifts of nitrate and phosphate
 concentrations are observable at the submicromolar level.
 Nonrecirculation of solutions limits problems of pH shifts,
 microbial contamination, and cumulative imbalances in
 unmonitored nutrients. We note several disadvantages,
 principally related to high consumption of deionized water and
 solutes. The reciprocating pumps can be constructed
 inexpensively, particularly by the researcher. We also report
 previously unattainable control of passive temperature rise of
 chambers exposed to full sunlight, by use of white epoxy
 paint.
