Sexual differentiation in cucumber: Abscisic acid and gibberellic acid contents of various sex genotypes

Michael Friedlander, Dan Atsmon and Esra Galun

Department of Plant Genetics, The Weizmann Institute of Science Rehovot, Israel

The AbA content of cucumber shoot tips was determined by GLC. Shoot tips of monoecious plants had a higher AbA content than those of gynoecious ones, and SD conditions caused higher AbA content than LD conditions. AbA content per unit dry weight of young floral buds was 5- to 9-fold higher than in older ones.

A GLC method was developed to allow parallel identification and quantitative determinations of GA3 and AbA with the same sample. The shoot tip contents of both growth substances were determined at four developmental stages of the monoecious plant. Both significantly increased until the 12th day after planting then decreased; the GA3 content decreased markedly.

A general hypothesis for the role of growth substances in regulating sex expression of cucumber is presented and discussed.
