Abstract
The influence of plant growth regulators ethrel (50, 100, 200 ppm), cycocel (25, 50, 75 ppm), and mepiquat chloride (50, 100, 200 ppm) on flower induction and sex forms of gherkin was investigated. Aqueous spray of each treatment was given on four leaf stage. Ethrel treatment brought down the number of days for the appearance of the female flowers and delayed the appearance of male flowers followed by cycocel and mepiquat chloride. Ethrel at 200 ppm had marked effect on the early appearance of pistillate flowers. Maximum number of female flowers and higher fruit set percent were recorded with 100 ppm ethrel.
