Summary

Results indicated that gynoecious stability in the F1 is governed by partial dominance. The degree of gynoecious stability is dependent upon genotypes, stages of plant for AgNO3 application and number of sprays. Depending upon the genotypes, the one-true-leaf stage and one spray of 250 ppm AgNO3 showed more gynoecious stability in the F1. Twice application of AgNO3 at the two-true-leaf stage produced the maximum number of male flowers. Plants exposed to light for longer time (10.00 h) after AgNO3 application produced less flowers than when exposed for shorter time (15.00 and 20.00 h).
