Ethylene Evolution from Cucumber Plants as Related to Sex Expression 1


Ethylene evolved from monoecious and gynoecious cucumber (Cucumis sativus) plants grown under short and long day conditions was determined. More ethylene was evolved from floral buds and apices bearing buds than from whole seedlings of comparable weight. More ethylene also was evolved from apices of the gynoecious than from those of the monoecious type. Furthermore, quantities evolved from female buds were greater than from male ones and plants grown under short day conditions which promote femaleness evolved more ethylene than those grown under long day conditions. The data suggest that ethylene participates in the endogenous regulation of sex expression by promoting femaleness.
