A Study on Daily Photosynthetic Course of Four Improved Clones of Camellia oleifera and Its Influencing Factors
摘要
Abstract
The photosynthesis of four improved clones of Camellia oleifera in Dabie mountain was measured by Li - 6400 portable photosynthetic system under natural condition, meanwhile, the relations between Photosynthesis parameters and its influencing factors were studied. This provides a basis for cultivation. The results showed that: (1) the curves of Pn diurnal variation of the four clones were alia single peak. Under consistent condition the relationships between Pn and Cond, Ci, light intensity were very significant or significant. (2)The Tr daily courses of the four clones were also obvious one-peak curve, but the Tt peak value did not appear in the consistent time; the major environmental factor affecting Tr for D, and D2 was light intensity, the major environmental factors affecting Tt for D3 were Vpdl and Cond, the major environmental factors affecting 7r for D4 were Ta and Cond; (3) WUE daily courses of leaves from different clones all presented a one - peaked curve decreasing at one side, D3 and D4 were more drought - tolerant by contrast. Ci was the largest factor influencing the WUE of D,, followed by Ta; Ta was the largest factor influencing the WUE of D2, followed by Ci; light intensity was the largest factor directly influencing the WUE of D3, followed by Ci; the direct impact of Ta, Vpdl and RH on its WUE were also very great;Ta was the largest factor influencing the WUE of D4, followed by Ci.关键词
