為探究不同葉色杉木葉片的光合作用能力差異,本研究選取了80株11年生杉木單株作為試驗材料,分別測定各個單株的葉色值、光合色素含量、葉綠素?zé)晒鈪?shù)和光合作用參數(shù)。結(jié)果顯示:1、80個杉木單株的葉色可基于對葉色的LAB model數(shù)據(jù)的聚類分析而分為2類,其中1類的葉色偏黃綠色,而另一類則偏青綠色。2、在葉片光合色素含量分析中,2種葉色類型的杉木葉片的葉綠素a（Chl a）、葉綠素b（Chl b）、總?cè)~綠素Chl（a+b）和類胡籮卜素（Car）含量,以及Chl a/chl b和Chl（a+b）/Car均存在極顯著差異。3、在葉片葉綠素?zé)晒鈪?shù)分析中,2種葉色類型的杉木葉片的最大PSII光量子產(chǎn)量(QY_<sub>max,Fv/Fm)、穩(wěn)態(tài)非光化學(xué)淬滅系數(shù)(NPQ_<sub>Lss)、穩(wěn)態(tài)光化學(xué)淬滅系數(shù)（qN_Lss）等參數(shù)的表現(xiàn)存在極顯著差異,初始熒光參數(shù)（Fo）和可變熒光參數(shù)（Fv）存在顯著差異,而最大熒光參數(shù)（Fm）和熒光下降比率(Rfd_<sub>Lss)沒有顯著差異。...
