Abstract

The present investigation was laid to standardize the seed priming durations for bitter gourd (Momordica charantia L.). Bitter gourd seed coat is hard. So it needs seed priming as it reduces the germination time, enhances the seedling emergence, germination percentage (%) and uniformity under normal as well as adverse climatic conditions. By keeping this in view, seeds of bitter gourd variety Kahalgaon Local were subjected to various seed priming treatments with different soaking durations keeping unprimed seeds as control. In case of hydro priming, increased soaking duration (18 hours) enhanced the seed germination and quality parameters compared to less soaking duration (12 hours). Among various osmo priming treatments, low concentration of PEG (2%) with less soaking duration (12 hours) gave good results at the same time increase in concentration of PEG (4%) with high soaking period (18 h) results in poor germination. In halo priming, increased in the concentration of KNO3 (4%) with

Conclusion

From this investigation it is concluded that, in case of hydro priming increased soaking duration (18 h) enhanced the seed germination and quality parameters compared to less soaking duration (12 h). Among various osmo priming treatments it is concluded that low concentration of PEG (2%) with less soaking duration (12 h) gives good results and increase in concentration of PEG (4%) with high soaking period (18 h) results in poor germination percentage. In case of halo priming, increased in the concentration of KNO3(4 %) with more soaking duration (18 h) enhanced the seed germination and seed quality parameters compared to remaining treatments. Among hormonal treatments, GA3 500 ppm with 18 h soaking period gives the best results in terms of seed germination, vigour index-I and Vigour index-II.
