In vitro evaluation of aqueous seed extract of Psoralea corylifolia L. on seed germination and seedling vigour of maize.

ABSTRACT

Aqueous seed extract of seeds of P.corylifolia were evaluated for seed germination and vigour index at 10, 20, 30, 40 and 50% concentration for 3,6, 12 and 24hours of treatment in maize seeds. Maximum and significant activity was observed in 20% concentration at 12hours of duration and recorded 88.0% germination and 1398.5 vogour index. Compared to control, it was recorded 72.1% germination and 1010.1 vigour index. In 30 and 40% concentration at 12 hours of duration, significant activity was recorded. In 6 hours of duration, moderate activity was observed in 10, 20, 30 and 40% concentration. No significant activity was observed in 3 hours and 24 hours duration at 10, 20, 30, 40 and 50% concentration of aqueous seed extract.
