EFFECT OF DIFFERENT CHEMICAL PRIMING METHODS ON GERMINATION AND SEEDLING PARAMETERS OF BLACKGRAM SEEDS

This study was done to determine the effect of different seed priming methods on germination and seedling parameters of black gram. The experiment was laid out in Completely Randomized Design replicated thrice. Treatment combinations were; control (no priming), hydro priming, Osmo priming (PEG-10% and 20%), halo-priming (1% NaCl and 1% KNO3), and hormonal priming (Salicyclic acid 125ppm). For all treatments, seeds were soaked for 12 hours and dried in ambient conditions, and grown for 8 days at 24°C in a germinator, and readings were taken. PEG (10%) exhibit the highest GP (96.8) followed by hydro priming (94.4). 1 % NaCl showed the highest value of GE and GI. The highest value of MGT was shown by PEG (10%). Whereas the highest value of CVG was given by Salicylic acid 125 ppm. The seedling parameters like root length (10.251), shoot length (10.671), and dry weight (4.580) was maximum in seeds primed with Salicyclic acid except for the SVI which was highest in PEG 10% primed seeds (1846.708). The lowest value of seed GP and SVI was shown by non-primed seeds. It was found that primed seeds were superior over non primed ones regarding parameters studied.
