Fig 19-48. Missionary strawberries. Center berry normal; outside, "puffed" berries with seeds far apart. Such puffed berries are much softer than the center berry, whose seeds are closer together, and, if developed normally, would be about half the size shown. "Puffing" occurs in ripe berries when warm humid weather occurs at ripening time. About 1933, on the Delaware peninsula, the crop of Howard 17 puffed during such a period and was almost a total loss. Howard 17 was then given up by growers in favor of Blakemore, which is more resistant to this trouble.
