Abstract

The experiment was conducted at Horticulture Experimental Area, Nursery, P.G. Department of Agriculture, Khalsa College, Amritsar during 2021-2022 to study the germination and growth parameters of Kainth. The experiment was laid out in Randomized Block Design replicated thrice, comprising ten treatments conc. H2SO4 for 5 and 10 minutes, KNO3 (1 % and 2 %) for 24 hours, Kinetin (0.50 ppm and 0.75 ppm) for 24 hours, GA3 (500 ppm, 1000 ppm and 1500 ppm) for 24 hours and control (untreated seeds). The results of the present study revealed that the Kainth seeds primed with GA3 @ 1500 ppm for 24 hours has recorded the minimum days required for initiation of germination (23.66 days), 50 per cent and complete germination (27.66 days and 34.66 days respectively) and maximum germination per cent (42.33 % and 64.33 %) was also recorded with seeds primed with GA3 @1500 ppm at 30 and 60 DAS respectively, which were statistically at par with the seeds treated with GA3 @ 1000 ppm for 24 hours. GA3 @ 1500 ppm treatment has also proved to be superior in the production of vigorous plant height (17.56 cm) with maximum number of shoots (14.00), stem diameter (4.27 mm), leaf number (45.00) and leaf area (39.90 mm2) at 30, 60, 90, 120 and 150 DAS.
