Abstract:
The effect of heat stress on photosynthetic activities of photosystem in leaves of Schisandra chinensis (Turcz.) Baill.‘Yanhong’ was studied by a portable fluorometer (PEA-Plant Efficiency Analyser).The results showed that Fv/Fm and ?ψ0 had not significantly changed at 35~40℃,but at 44℃ and 48℃ there was a significant decrease.It indicated that the acceptor side was inhibited severely.With the increasing of temperature,the relative variable fluorescence Vk and Vj increased gradually and became significantly higher at 44℃ and 48℃.When time of heat stress increased from 5 min to 40 min,Vk and Vj increased gradually,bimodal curve was observed at K point and J point after heat stress was kept in 5 min.Although Vk increased gradually as heat stress time prolonged,K point disappeared gradually and J peak became more prominent.Above all,both the donor side and the acceptor side of PS Ⅱ were damaged,especially the donor side,were more sensitive to heat stress.
