Title

Recovery of deteriorated cotton seed and improving quality by using gibberellic acid

Pages

  35-51

Abstract

 Deterioration of seeds is an important factor to reduce seeds vigor and limit germination. The purpose of this research was to evaluate the influence of gibberellic acid hormone on recovery of seeds and improvement of quality and seedling growth in Varamin cotton seed, an experiment was conducted in a completely randomized way in three replications. Treatments included: two levels of deterioration (48 and 96 hours) plus control, Gibberellic acid solution with two concentrations of 500 and 1000 ppm plus control and the time to apply hormone treatment in three ways (before deterioration, after deterioration, before and after deterioration). The results showed that in non-deterioration treatments, in the concentration of 500 ppm, the peroxidase, carotenoid, and electrical conductivity ratios had the best conditions and at 1000 ppm, catalase and chlorophyll a and b had the best results. In primitive applications before deterioration at a concentration of 500 ppm, the electrical conductivity was the best and at concentration of 1000 ppm, catalase, peroxidase, chlorophyll a and b, and carotenoids were at the highest levels. In primer applications after the deterioration, at concentration of 500 ppm, electrical conductivity was in better conditions and had better conditions at 1000 ppm, catalase, peroxidase, chlorophyll a and b, and carotenoids. In the priming test before and after deterioration, at a concentration of 500 ppm, electrical conductivity has the best results. At 1000 ppm concentration, catalase, peroxidase, chlorophyll a and b and carotenes had the best value. In general, the use of gibberellic acid has led to retrieve and improved seeds are deteriorated.
