摘　　要：以2种决明属植物草决明和望江南为试材,采用PAM-2500型叶绿素荧光仪,研究了时刻、物种及其交互作用对2种决明属植物的影响。结果表明:草决明的Fm、Fv/Fm和ETR均小于望江南,而草决明的Fo却大于望江南。时刻对2种决明属植物的Fo、Fm和ETR的影响均存在显著性差异,对Fv/Fm存在极显著性差异;物种对Fo和Fm的影响不存在显著性差异,对Fv/Fm存在显著性差异,对ETR存在极显著性差异;时刻和物种之间的交互作用对Fo、Fm和ETR的影响存在显著性差异,对Fv/Fm存在极显著性差异。随着光照强度的增强,2种植物表现出明显的光抑制现象,其中,草决明>望江南。Taking two species of C.obtusifoliaand C.occidentalis plant as test materials,the effect of the concentration of time,species and their interaction on two species of Cassiaby PAM-2500 type chlorophyll fluorescence were studied.The results showed that C.obtusifoliaof Fm,Fv/Fmand ETRvalues were less than C.occidentalis,and C.obtusifoliaof Fo was greater than C.occidentalis.Time for two species of Cassiaof Fo,Fmand ETRhad significant differences,there were very significant differences on Fv/Fm;species had no significant difference on Fo and Fm,there was a significant difference on Fv/Fm,there were very significant differences for ETR;the interaction between time and species had significant differences on Fo,Fm and ETR,there were very significant differences on Fv/Fm.As the light intensity increases,the two species showed significant inhibition of light,which C.obtusifolia〉C.occidentalis.
