SEED GERMINATION AND GROWTH PARAMETERS OF FIRETHORN (PYRACANTHA CRENULATA M. ROEM.) AS INFLUENCED BY DIFFERENT SOWING DATE AND GIBBERELLIC ACID CONCENTRATIONSKrishna, Madhulika Pandey, Manju Negi, Deeksha Rawat1 and Rishabh RajAbstract A field experiment was conducted at Farm area of IMAP, Gairsain, Chamoli during the crop growing season of 2020-21 to study the response of three different date of sowing (15th October, 30th October and 15th November) and five Gibberellic acid concentrations (50, 100, 150, 200 and 250 ppm) on germination and growth parameters of Firethorn. The experiment was conducted in Factorial Randomized Complete Block Design with 3 replications and 15 treatment combinations. The findings of the investigation indicated that seeds treated with 150 ppm Gibberellic acid and sown on 15th November resulted in maximum germination (60.0), survival percent (88.0), shoot length (28.22 cm), shoot diameter (9.95 mm), number of leaves (628.80), number of branches (42.0), shoot fresh weight (21.77 g), shoot dry weight (10.91 g), root length (28.22 cm), root diameter (9.73 mm), number of roots (58.87), root fresh weight (6.25 g), root dry weight (3.40 g), total fresh weight (28.02 g) and total dry weight (14.31 g) as compared to other treatment combinations. |
