The germination percentage of eggplant seeds based on pretreatments effects

Abstract

Five genotypes were selected with 2 lines (33 and 34 not dormant) for testing was used. Three genotypes originating from germplasm collection eggplant Institute: 2-02619 (dormant), 7-00568, 12 - 0082. The cooling treatment (HLS) was performed at 4°C for 96 hours (4 days), 72 hours (3 days) and 48 hours (2 days) continuously. Hormonal treatment with gibberellic acid (GA3) is made with three concentrations: 5 ml / 100 ml; 15 ml / 100 ml and 25 ml / 100 ml, for 24 hours after which the seeds are placed to germinate. Chemical treatment was carried out as potassium nitrate KNO3 at a concentration of 0,5, 1 and 1,5% solution for 24 hours. Control treatments (time) to overcome the natural dormancy: kon-3, kon-6 and kon-12, the examination of germination after 3, 6 and 12 months of storage. Genotype - 2 after growing trend determined phase of stagnation trend. The negative sign of the coefficient c indicating deterioration phenomena, ie the aging of seeds. The growth trend in the first quarter is the result of passing phases of dormancy at L-7 in the period 3-6 months. Dormancy period of 3-6 months, led to a stagnation of growth after germination which continued to grow.
