臭氧浓度升高对大豆光合作用及产量的影响
Effects of Elevated Ozone Concentration on Soybean Photosynthesis and Yield
摘要
Abstract
In recent years, the elevated ozone has some significant effects on plant photosynthesis, respiration, water availability and so on. In this paper,the effects of the elevated ozone concentrations on soybean photosynthesis and yield were studied in use of open- top chambers. Photosynthetic traits of Pn,Gs, Ci, Tr and contents of Chla, Chlb, Chi (a+b) and Chla/b were determined. The results showed that Pn reduced significantly(P <0. 01) ,Gs ,Ci and 7Vascended firstly and declined following,the contents of Chla,Chlb,Chi(a+b) and Chla/b of soybean leaves under elevated ozone (110 nmol·mol~(-1)) were lower than that of control. The decrease of 100- seed weight of soybean was not significant(P>0.05) , but the decrease of grain weight per plant and grains per plant was significant P <0. 01). It indicates that elevated ozone has more negative influence to the soybean, which reduces the soybean photosynthesis intensity and the amount of flowers and inhibits the process of pollen fertilization, thus reduces the yield on soybean.关键词
