Description Tulsi, holds a revered status in various cultures around the world for its medicinal, culinary, andspiritual significance. This study was conducted for optimizing the germination test and seed quality parametersat alternate temperature of 20-30°C in Tulsi during 2022 in the laboratory of Department of Seed Science andTechnology, CCS HAU Hisar. Various dormancy-breaking treatments were used during the study such as, GA3 @0.05 and 0.1% for 24 hours, KNO3@ 0.2% for 24 hours, Pre-chilling (5-10oC for 7 days), and Light treatments (16hours light followed by 8 hours darkness). The results revealed that the germination percentage, seedling length,seedling dry weight, vigour index-I and vigour index-II was recorded maximum in top of the paper (TP) with theGA3 0.1% treatment and the minimum was recorded with control in sand substrate at 20-30oC alternate temperature.The radicle emergence was recorded maximum with GA3 @ 0.1% at 7th day at 20-30oC alternate temperature.The dormant seeds were observed maximum with control in BP and the minimum dormant seeds were recordedwith GA3 0.1% in TP at 20-30oC alternate temperature. The research reveals significant effects of these treatmentson seed germination and other crucial seedling parameters. Seeds treated with GA3 0.1% exhibited substantialimprovements in germination percentage and overall seedling quality. These findings highlight the efficacy of GA3treatment in enhancing the germination process and seedling establishment of Tulsi under specified temperatureconditions.
