Abstract:

The present experiment was carried out during Kharif (2016) at the Experimental Research Farm, Department of Vegetable Science, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) to gather information on use of chemicals (Gibberellic acid, Silver nitrate and Silver thiosulphate) in modification of sex expression in gynoecious varieties (GYNO-1 and GYNO-2) of cucumber. The experiment was laid out in a RCBD with three replications. Use of chemical in modification of sex expression was assessed through factorial analysis in randomized block design. The treatments consist of three chemicals viz., Gibberellic acid (500, 1000 and 1500 ppm), silver nitrate (250, 500 and 750ppm) and silver thiosulphate (250, 500 and 750ppm) along with control (distilled water) were sprayed at 2-3 true leaf stage at five days interval till 10-15 leaf stage. Amongst the various treatments, chemical silver thiosulphate (Ag2S2O3) induced maximum number of mean male flowers followed by silver nitrate (AgNO3) and gibberellic acid (GA3) whereas no male flower has been recorded in control treatment (Distilled water) in gynoecious cucumber cultivars. Silver thiosulphate in higher concentrations was found less deleterious in comparison to silver nitrate.
