Effect of relative humidity on fruit set and seed set in pepper (Capsicum annuum L.).

Abstract

During 1976, plants of the sweet-pepper variety Verbeterde Glas [Improved Glass] were placed in growth rooms at 55, 80 or 95% relative humidity, at the onset of flowering. The flowers were artificially pollinated until flower drop, and the plants were moved to the glasshouse for the fruit-ripening period. Fruit set was not influenced by relative humidity, but seed set increased with increasing humidity. Time from pollination to harvest was significantly shorter at 95% relative humidity.
