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.
测定了雌雄同株和雌雄异株黄瓜（Cucumis sativus）在短日照和长日照条件下产生的乙烯量。与具有可比重量的整个幼苗相比，来自带有芽和顶芽的花芽产生了更多的乙烯。来自雌性型的顶芽产生的乙烯也比来自雄性型的顶芽多。此外，来自雌性芽的乙烯量大于来自雄性芽的乙烯量，在促进雌性的短日照条件下生长的植物比在长日照条件下生长的植物产生更多的乙烯。这些数据表明，乙烯通过促进雌性来参与性表达的内源性调节。
