Abstract

 

The effect of different concentrations of Cassia alata crude aqueous leaf extract on the germination ofCorchorus olitorius was investigated. All concentrations of C. alata aqueous leaf extract (10, 30, 50, 75 and 100% C) used in this study caused significant (P < 0.05) decrease in the total percentage and germination rate of C. olitorius. Similarly, all concentrations of this extract significantly (P < 0.05) inhibited radicle elongation in C. olitorius. Pre-soaking of C. olitorius seeds in C. alata crude aqueous leaf extract led to an increase in the lag-phase period preceding germination of the seeds in a concentration-dependent manner. The total percentage and rate of germination decreased as extract concentration increased. All concentrations caused a consistent decrease in absolute rate and percentages of germination compared to the control.

 

Key words: Cassia alata, Corchorus olitorius, aqueous extract, germination.
