The drought resistance of six Lolium perenne fodder varieties at the seedling stage was studied by using PEG-6000 solution to simulate drought stress in the green house.The physiological and biochemical indexes such as relative water content(RWC),exosmosis rate of cytoplasm(RPP),proline content(Pro),chlorophyll contents(Chl),content of malondialdehyde(MDA),activities of superoxide dismutase(SOD)and CAT were measured.Drought resistance was evaluated by principal components analysis and subordinate function analysis.Results show that the seven significantly different drought-resistance indexes could be classified into 3 component parts.The capacity of drought resistance of the six Lolium perenne fodder varieties is gauged as follows:OupecToveNulEminentPolimYatsyn.
