Effect of leaf extract of some plants on seed germination and seedling
Some allelochemicals present in plants showed effect on germination. In present study effect of 15 aqueous leafs extract at 6 hour soaking period and (10%) concentration were tested on seed germination and seedling development of pigeon pea. The distilled water was used as control. The Eupatorium odoratum L. and Pogamia pinnta (L.) Panigrahi both plant extracts showed stimulatory effect on seed germination and seedling development as compare to control after 7 days, followed by Cassia uniflora Mill, Ipomoea carnea Jacq , Hyptis suaveolens( L.) Poit., Achyranthus aspera,L These plants showed positive result in case of root length and shoot length as compare to control. Ramming Lantana camara, Ageratum conyzoides(L.)L, Tridax procumbens, Alternanthera sessilis, (L.) R.Br, Xanthium strumarium L., Oxalis corniculata L., Vitex negando L., Parthenium hysterophorus L., Arginum maxcina L. inhibitory effect on root and shoot length and vigor index.
