模拟酸雨对有性繁殖香根草光合速率的影响
首发时间:2004-08-04
摘要:使用LI-6400便携式光合作用系统研究了模拟酸雨对有性繁殖香根草光合速率(Pn)的影响。结果表明:酸雨对光合速率的影响比较明显,低浓度(pH=4.5)的酸雨对香根草的Pn有一定的促进作用;而在高浓度(pH≤3.5)条件下,Pn随酸度的增强而减小。可见,有性繁殖香根草有一定的耐酸能力。

Effect of Simulated Acid Rain on Photosynthesis Rate of Sexual-Reproductive Vetiveria zizanioides
Abstract:Having studied the effect of simulated acid rain on photosynthesis rate(Pn)of sexual-reproductive Vetiveria zizanioides by LI-6400 portable photosynthesis system.The results showed that as following:acid rain affected Pn were dominant,acid rain could enhance Pn of Vetiver grass in low concentration (pH=4.5),but it became smaller in high concentration(pH≤3.5);sexual reproductive Vetiveria zizanioides has determinate capabilities of acid –tolerance.
Keywords: simulated acid rain;photosynthesis rate;sexual-reproductive Vetiveria zizanioides
