SUMMARY
The study was conducted to optimize the germination test and assess seed quality parameters in Kasani during 2022 in the laboratories of the Department of Seed Science and Technology, aimed. The results revealed maximum germination was recorded in Top of Paper (66.67%) method at 25°C and lowest germination (38.67%) was recorded at 30oC in sand substrate. Maximum hard seeds (17.33%) were recorded in between paper at 30°C and lowest hard seeds (7.33%) at 20°C in top of the paper. The other seed quality parameters viz., seedling length, seedling dry weight, vigour Indices and radicle emergence were also observed maximum at 20°C. The radicle emergence was started on 1st day in all temperatures except at 15°C temperature. From 2nd day radicle emergence was observed in all temperatures and till the final day the maximum radicle emergence (74.67%) was observed at 20°C. Thus, the study concludes that for conducting the germination test in Kasani crop, the optimum temperature is 20°C, and both the top of the paper (TP) and between paper methods are suitable.
