Abstract
Laboratory trials were carried out to evaluate the effect of concentrated sulphuric acid (98%) and hot water on the germination capacity of four wild and one cultivated species of Crotalaria viz C. laburnifolia L, C. pallida Aiton, C. medicagenea Lam, C.retusa L and C. juncea L. Hot water treatment at 80°C for 5 min. was found to be most effective in breaking hardseededness in C. laburnifolia. The percentage of hard seeds declined sharply in C. medicaginea, and C. retusa when soaked in water at 70°C for 15 min.
In C. pallida soaking seeds in hot water at 60°C for 30 min enhanced germination.
Acid scarification was also found to be effective in breaking the dormancy but had undesirable effects and resulted in maximum of abnormal seedlings and dead seeds.
Subjecting seeds to dry heat and mechanical scarification was found ineffective in removing hardseededness.
