ASSESSMENT OF VITALITY POTENTIAL AND STORABILITY OF PEPPER SEEDS BY THE METHOD OF ACCELERATED AGEING

N. Panayotov

Abstract: The object of the present study was to investigate the possibilities for evaluation of viability, vigour and storability of sample of pepper seeds with different origin by accelerated ageing test and to optimize the regime for its implementation. The experiments were carried out with varieties Kurtovska kapia 1619, Bulgarski rotund and Delikates, produced in three different regions Vardim, Stryama and Plovdiv. Accelerated ageing test was conducted by described method of ISTA. Three temperature regimes - 350С, 400С and 450С and three periods - 24, 48 and 72 hours were examined. After treatment, the seeds were subjected to standard germination test. The germination energy (first count), germination (final count), mean germination time, uniformity of germination, length of embryo root and hypocotyls, fresh and dry weight of seedlings and percentage of seedlings with deviation were analyzed. The optimum temperature regime about accelerated ageing of pepper seeds was established in temperature 400С for 48 hours. The initial seeds with best characteristics were these with origin from Varidim. Higher sensitivity to accelerated ageing demonstrated the seed of Bulgraski ratund, Vardim. The highest vigor and storability were established about seeds from variety Delikates from Vardim.
