摘要：

Floral biology and sex determination are reviewed in cucumber, one of the best studied monoecious plant systems. Sexual differentiation is controlled by genotypic and environmental factors. Sex conversion has been achieved by a variety of chemical treatments, some of which being extensively used for commercial purposes. Sex expression can be shifted in either direction: femaleness is promoted by ethylene, auxines and ethylene releasing compounds, while maleness is induced by gibberellins and chemicals counteracting ethylene action. Agrobacterium transformation affects, albeit rather nonspecifically, sex expression. An important collection of sex and floral mutants has been developed. The expression of sex genes has been shown to be under the control of modifier genes or the environment. Cloning strategies can take profit of the fact that sex conversion can be modulated alone or in combination by genetical, chemical and/or environmental parameters.
