Three inherent acidic chitinases were purified from yam aerial tuber by the application of quaternary ammonium ion detergent. For remoyal of the mucilage in the crude extract of aerial tuber, the effeets of various quaternary ammonium ion detergent were compared. Cetylpyridinium chloride effectiyely remoyed the mucilage and this method proyed to provide high recoyery of chitinase actiyity. Thre...

leaf and root explants from 10 to 20 day– old seedlings of plantago lanceolata, were cultured on ms, msh, nt and b5 basal media with various concentrations of different plant growth regulators. the best callus induction was obtained with 0.4 mgl-1 2,4-d in msh i with 400 callus index. callus growth was significantly stimulated (p=0.05)with 0.8 mgl-1 2,4-d and 0.1 mgl-1 kin in msh ii, with 7...
