BIOSTIMULANTS WITH AMINO ACIDS USED FOR IMPROVING SEED GERMINATION AND SEED VIGOR INDEX IN EGGPLANT

Eggplant seed production is an important activity in breeding and cultivars maintaining of this species. Our research paper presents the influence of foliar treatments with biostimulants with amoni acids applied during the vegetation period, on the dynamics of seed germination, the percentage of germinated seeds and seed vigor index at eggplant. Biological material consist of two Romanian eggplant cultivars, Luiza and Belona. Four treatments were carried out, at 14 days interval, starting from the fruit setting. Three biostmulants were used for the treatments, Florone, Florabax and Rerum. After the fruit harvesting at physiological maturity, the seeds were extracted and used for assessing the germination dynamics in the laboratory. The seeds were placed on Petri dishes at 20OC for 16 hours and 30OC for 8 hours. After 14 days, germinated seeds were analysed for evaluation of sprouts, to calculate seed vigor index. Our results concluded that foliar treatments applicated in vegetation period with Florabax and Rerum can improve the seed germination process and have a positive influence on the percentage of germinated seeds and seed vigor index at eggplant.
