RESULTS The SOD activity had linear correlation with pH in the range of pH 2.2-8.0 when SOD concentration was fixed. The varication of activity after ultrosonication had linear correlcation with fluoresent intensity at 340 nm. With increase of uhtrosonic frequency, the microenviroment of tyrosine and tryptophan inside the SOD molecule was changed, then the balance of hydrophokicity and hydrophilicity inside the molecule was broken, this induced the blue shift of synchronous spectrum band and decrease of SOD activity.
结果 SOD浓度一定、pH2.2~8.0时,活性与其线性相关,超声后活性差值与340 nm荧光强度差值的线性相关;随着超声次数的增加,蛋白质SOD分子内部的酪氨酸、色氨酸所处的微环境被扰动,打破了分子内部的疏水和亲水平衡,使蛋白质的活性降低,在荧光检测中观察到普通荧光谱带蓝移,同步荧光的荧光峰位总体呈现峰位蓝移和强度下降。

The comprehensive evalucation resulted in a strong drought resistance group including ZXY04P-201、ZXY03P-227、ZXY03P-122 and ZX Y04P-136, a weak drought resistance group including ZXY04P-101、ZXY04P-89,ZXY04P-239 and a intermediate group including the others according to the the above indicators. 3. The results of study on drought mechanism for 4 Dactylis glomerata L. under continuously water stress and rewatering show: the water saturation deficit of leaves arose hastily, and ZXY04P-239 changed most obviously while ZXY04P-201 changed only slightly under drought stress. ZXY03P-173 and ZXY04P-201 increased in the relative plasmalemma permeability and the soluble sugar content while thant of ZXY04P-75 and ZXY04P-239 showed the trend of initial increasing, reaching the peak at the 8th day, then decreasing under drought stress.
