Applied with test of potted plant and measurement absorbency for study physiological response of activity of cell defense enzymes and lipid peroxidation of slash pine's half-sib under water stress. There are 7 families comparison with general slash pine. The contents of superoxide dismutase, catalase, antioxidant, malondialdehyde and the rate of superoxide anion(-O2) generating are mensurated under normal water condition while soil water content is 70% and light water stress while soil water content is 55% to 60% and medium water stress while soil water content is 35% to 40% and heavy water stress while soil water content is 20% to 25%. The test result indicate that either water grads or families of contents of SOD,CAT,AsA,MDA are mighty notable difference. The rate of -O2 generating is notable difference within families. The rate of -O2 generating is mighty notable difference within water grades.

为研究湿地松优良半同胞家系保护酶及脂质过氧化作用对水分逆境的生理响应,采用盆栽试验和吸光度测定结合的方法,以普通湿地松种子为对照,测定了七个湿地松半同胞家系在正常水分状态(土壤相对含水量为70%)、弱度水分胁迫(土壤相对含水量为55%~60%)、中度水分胁迫(土壤相对含水量为35%~40%)和强度水分胁迫(土壤相对含水量为20%~25%)条件下的SOD、CAT、AsA、MDA的含量和-O2产生速率,研究结果表明:无论是不同水分梯度还是不同家系水平,SOD、CAT、AsA活性和MDA含量的差异均达极显著水平,不同家系水平间-O2产生速率有显著差异,不同水分梯度间-O2产生速率差异达极显著水平。

Applied with test of potted plant and measurement absorbency for study response of the contents of photosynthetic pigments of slash pine's half-sib under water stress. There are 7 families comparison with general slash pine. The contents of photosynthetic pigments are mensurated under feebleness water stress while soil water content is 55% to 60% and moderate water stress while soil water content is 35% to 40% and heavy water stress while soil water content is 20% to 25%. The test result indicate that either water grads or families of chlorophyll and chlorophyll a and chlorophyll b and Chla/Chlb and carotenoid and Caro/Chl are mighty notable difference. The Chl and Chla and Chlb and Chla/Chlb little drop from normal soil water to initial water stress. Then drop obvious with increased water stress. The Caro and Caro/Chl little drop firstly from normal soil water to initial water stress,then up in metaphase water stress,after drop in evening water stress. The Chl and Chla and Chlb and Chla/Chlb and Caro of slash pine'half-sib are over general slash pine. The Chl and Chla and Chlb and Chla/Chlb and Caro of 464 and 1027 are over average value of slash pine's half-sib under water stress. The Caro/Chl of 609 and 46 are over average value of slash pine's half-sib under water stress.
