Role of Seed Hardening in Rice Variety Swarna (MTU 7029)

S. Mondal, P. Vijai and B. Bose

Abstract:
In the present study the effects of hydro and halo hardening of seeds with distilled water and Mg(NO3)2, respectively, were observed on the performance of rice (Oryza sativa L.) var. Swarna (MTU 7029) starting from its germination to vegetative growth. Maximum amylase activity in endosperm correlated well with an increase in soluble sugar content were noted in halo hardened seeds of rice, whereas in the same treatment the insoluble content was noted to reduce maximum in comparison to hydro hardened and non-hardened sets. Studied growth parameters like plumule/shoot length, radicle/root length, fresh and dry weights of seedling, root number, proline content, total nitrogen content in seedlings and nitrate reductase activity in leaves were found maximum in Mg(NO3)2 hardened one followed by other two treatments.
