Allelopathic Effect of Four Extracts from Asparagus officinalis on Selected Receptor Plants
Using Brassica pekinensis,Eupatorium catarium and Rhynchelytrum repens as receptor plants,the allelopathic effects of four extracts from fresh leaves and stems of A.officinalis were studied by bioassay methods.Leaf and stem extracts from A.officinalis strongly inhibited R.repens growth.The four solvent extracts promoted seed germination of E.catarium at low concentration,but had the opposite effect at high concentrations.The four extracts increasingly inhibited root and shoot length of E.catarium,as their concentration increased.The four extracts also inhibited seed germination and root length of B.pekinensis but stimulated its stem length.This study documents different allelopathic effects of the four extracts on seed germination,root length and stem length of the receptor plants,and provides a theoretical foundation for controlling weeds with allelochemicals from A.officinalis.
