Abstract

Studies were made of isozyme patterns of three enzymes and of total soluble proteins from seedlings of three crop species which were grown in association with different weed species. The gel electrofocusing separation technique was used. Marked qualitative and quantitative changes were observed in peroxidase of cabbage (Brassica oleracea L.) seedlings when grown in association with jimsonweed (Datura stramonium L.), velvetleaf (Abutilon theophrasti Medic.), wild mustard (Brassica kaber DC.), and green foxtail (Setaria viridis (L.) Beauv.). No differences were observed when lettuce (Lactuca sativa L.) and tomato (Lycopersicum esculentum Mill.) were grown in association with the above weed species. No differences were found in total soluble proteins or the isozyme patterns of esterase and acid phosphatase.
