Abstract

The development of short-internode cantaloupes has been of interest for a number of years because of the obvious advantages of potentially larger plant populations and, more recently, mechanical harvest. In those areas where furrow irrigation is practiced, the savings in labor requirement to keep vines trained up on the beds is also a factor.

Abstract

Plants and detached fruits of mature green bell peppers (Capsicum annuum L. cv. Yolo Wonder B.) were treated with (2-chloroethyl)phosphonic acid (ethephon) and 2-(4-chlorophenylthio)triethylamine hydrochloride (CPTA) to enhance red color development. Ethephon sprayed on plants in the field greatly enhanced red color development in fruits in 1971. However, in 1972 when temperatures were cooler after spray treatments than in 1971, neither ethephon nor CPTA affected fruit color even though plants showed the effects of chemical treatment by turning slightly chlorotic. Furthermore, dipping detached fruits in ethephon had no effect, but fruits dipped in CPTA turned yellow instead of the usual red color.

Abstract

The environment created by ventilating a greenhouse with mine-air was suitable for the production of high quality spray chrysanthemums (Chrysanthemum morifolium Ramat.) and snapdragons (Antirrhinum majus L.) from mid-February through November without any additional energy requirement. The environment created in the greenhouse from December to February was extremely humid and favored botrytis development and physiological problems which reduced crop quality.
