Induced Femaleness in Cucumber by 2-Chloroethanephosphonic Acid

Abstract

SEX expression of cucumber can be altered by exogenous plant growth regulators1–3, as well as by environmental conditions, such as temperature and day length. The work described here was undertaken to test the induction of femaleness in cucumber plants by 2-chloroethane-phosphonic acid (CEPHA), as a presumptive substitute for ethylene, both in the greenhouse and field.
