Physilolgical response of different allelopathic types of Chinese fir clones to continuous cropping obstacles soil
摘要
Abstract
To reveale the response mechanisms of different allelopathy types of Chinese fir clones on continuous cropping soil, Chlorophyll content[Chla, Chlb, Chl(a+b), Chla/Chlb], chlorophyll fluorescence parameters(Fo, Fm, Fv, Fv/Fm, Fv/Fo), antioxidant enzymes ( SOD, CAT, POD, PPO) activity and malondialdehyde ( MDA) content was investigated in different planting generations of Chinese fir plantation soil medium which was cultivated 1-year-old Chinese fir clones through pot experiment method. The results showed:(1) Compared with the CK, Chla, Chlb, Chl(a+b), Fm, Fv, Fv/Fm, Fv/Fo of Chinese fir clones declined with the increasing successive rotation, Chla/Chlb, Fo , antioxidant enzyme activity and MDA rose with the increasing successive rotation. (2) In the same forest types of soil, the value of endurance clones was higher than sensitive clones in chlorophyll content, chlorophyll fluorescence, however, endurance clones was lower than sensitive clones in antioxidant enzyme activity and MDA. Different Cunninghamia lanceolata clones existed significant difference in the same stand′s soil. ( 3) Correlation analysis between chlorophyll content and chlorophyll fluorescence parameters of Cunninghamia lanceolata showed that Chla, Chlb and Chl(a+b) was negatively correlated with Fo , significantly positive correlated with Fv/Fo;Chla/Chlb was negatively correlated with Fv , Fv/Fm , Fv/Fo .关键词
