Abstract:
The present study aimed at assesses the effect different concentration of chlorate in breaking dormancy of Four Varieties of Cyamopsis tetragonoloba seeds. The four varities of seeds (RGC 936, RGC 1002, RGC 1003 and RGC 1017) was collected from Agriculture Research Centre Durgapura, Jaipur, Rajasthan. Seeds were again treated using different concentrations of Clorox (NaOCl) i.e 0.5 %, 1%, 2%, 3% and 4% for 12 hours. A total of 10 seeds of each variety were placed in 90-mm-diameter Petri dishes on 2 layer of Watman No. 1 filter paper soaked with sterile distilled water and untreated seeds of each variety were grown in sterile distilled water as control. In comparison to control treated seeds were observed for germination percentage, radical length, plumule length, seedling length, seedling vigour index (SVI), fresh weight and dry weight. The results of the present study, thus, indicate the treatment of seeds with 4% NaOCl is most effective in seed germination although one type of seed remained dormant in the experiment which shows that some other method for breaking its dormancy is required for further study.
