不同光照强度对幼龄期两面针光合特性及叶绿素含量的影响
The Effect of Photosynthesis Characteristics and Chlorophyll of the Young Zanthoxylum With Light Stress
【摘要】 研究不同光照强度处理对两面针叶片光合特性、叶绿素含量的影响。结果表明:不同光照强度处理对光饱和点LSP、光补偿点LCP、表观量子利用效率影响不显著;对叶绿素a、叶绿素总量、最大净光合速率影响达到显著水平;不同光强处理下叶绿素b含量差异达到极显著水平。
【Abstract】 The effect of the content of photosynthesis characteristics and chlorop hyu in the leaves of Zanthoxylum were studied with light stress.The results showed that light stress wasn’t significant influence on LSP,LCP,but significant(Sig<0.05) on chla、chlt and Pn(max) and significant variation(Sig<0.01) on chlb.
