Abstract

The present study was conducted to study the dormancy breaking treatments in babchi seeds. The aim of this study was to enhance the germination of seeds, which have a low percentage under normal conditions. Different pretreatments (soaking in cold, hot water and concentrated H2SO4, scarification with H2SO4) were carried out with different concentrations and durations. The percentage of seed germination varied with duration and concentration of treatments. The results revealed that all treatments showed increased germination compared to that of control. The hard seed coat dormancy of the seeds could be broken by scarifying the seeds with concentrated H2SO4 @ 200 ml kg-1 of seeds for 30 minutes. It improved the germination to 95 per cent which was 87 per cent higher than control. The dead seed percentage also very low in this treatment when compared to soaking the seeds in concentrated H2SO4.
