摘要
以3种决明属植物草决明、望江南和伞房决明为试材,研究不同时刻3种植物叶绿素荧光特性。结果表明:在3种决明属植物中,草决明的Fo、Fm、Fv/Fm均最大,但ETR值最小。时刻对3种决明属植物的Fo和Fv/Fm都有极显著性差异,对ETR有显著性差异;物种对Fm和ETR有显著性差异;时刻和物种之间的交互作用对Fo、ETR有显著性差异。随着光照强度的增强,3种植物表现出明显的光抑制现象,其中,伞房决明>草决明>望江南。
Taking three species of Cassia,Cassia obtusifolia,Cassia occidentalis,Cassia corymbosa as materials,chlorophyll fluorescence characteristics at different time were studied.The results showed that in the three kinds of Cassia,Fo,Fm,Fv/Fmof C.obtusifoliawere the biggest,but ETRwas the minimum value.Effect of time on three kinds of Cassiaof Fo and Fv/Fm had a very significant difference,there were significant differences of ETR;the species had significant differences on Fmand ETR;the interaction between time and species had significant differences on Foand ETR.As the light intensity increased,the three species showed significant inhibition of light,C.corymbosaC.obtusifoliaC.occidentalis.
