摘要

The present investigation deals with the aqueous leaf and stem extracts of Andrographis lineata Nees which showed inhibitory effects on seed germination, plumule and radicle length of crop plants Vigna mungo Hepper var. T 9 (blackgram) and Vigna radiata Wilczek var. CO 6 (greengram). The results showed that the extracts brought about considerable inhibition in the germination of Vigna mungo and Vigna radiata seeds and in the growth of its radicle and plumule. The germination percentage in the aqueous extracts treated seeds decreased with the increase in the concentration of the extracts thus indicating that the degrees of inhibition were concentration dependent. It was apparent that A. lineata leaf extracts had more inhibitory effects on V. mungo seeds than those from the stem extracts. In A. lineata extract treated seeds, radicle growth was observed clearly at 48 h of the experiment, whereas radicle growth was recorded at 24 h experimental time in the leaf and stem extracts. Also in A. lineata extracts plumule growth occurred at 72 h of the experiment, whereas plumule growth was recorded at 48 h experimental time in the leaf and stem extracts treated seeds. These results revealed that the inhibitory effect might be due to the presence of these allelochemicals in the extracts of A. lineata.
