Abstract
In this paper,we researched the stress physiology of three kinds of Bermudagrass cultivars('Unhulled','Savannah','Jackport') by measuring the content of H2O2,the ratio of elecotrolyte leakage,the contents of MDA and SOD,the content of soluble protein in the leaves under the immitaion of drought stress and alkaline stress with the PEG6000 and NaOH.The results are given as follows: Suffered from drought stress and alkaline stress,the content of active oxygen in the leaves increased,leading to cell membrane damage,activating the protective enzyme system and producing penetration adjusting materials.The content of H2O2 in the leaves of three caltivars increased along with time.The ratio of elecotrolyte leakage in leaf for three caltivars increased firstly and then decreased.The SOD content in the leaf of three caltivars decreased firstly,then increased,at last decreased again.The change of MDA content in the leaf of three caltivars is opposed to that of SOD.The content of soluble protein in the leaf of three caltivars changed little in prophase,and increased distinctly after 4 days of treatment.
