The net photosynthetic rate and maximum net photosynthetic rate of slash pine's half-sib around 1 year is studied utilities of LI-6400 portable photosynthetic system so as to study on the seasonal variation and difference on net photosynthetic rate. The result showed that the seasonal variation of net photosynthetic rate and maximum net photosynthetic rate of slash pine's half-sib is double range curve. There is no notable difference on net photosynthetic rate among needles with same half-sib. There is notable difference on net photosynthetic rate with same needles among half-sib. The net photosynthetic rate of 1 year needle of half-sib 464 and 609 and 1077 is over than others.

为研究湿地松半同胞家系间净光合速率的差异及其季节变异规律，应用LI－6400便携式光合测定系统，对湿地松优良半同胞家系一年中各月净光合速率、最大净光合速率进行了研究，结果表明一年中湿地松各半同胞家系1龄针叶、2龄针叶净光合速率、最大净光合速率的季节变异规律呈'双峰'型，家系内不同单株同龄针叶的净光合速率值没有显著差异，而家系间相同年龄针叶的净光合速率值则存在着显著差异。

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。
