Abstract
Using 9516,Wuyujing, Zhendao8, Kitaake as materials, effects of nitrogen deficiency on the photosynthetic characteristics of different varieties of japonica rice were studied. The chlorophyll content,root-shoot ratio, photosynthetic rate(Pn), stomatal conductance(Gs), intercellular CO2(Ci) and transpiration rate(E) were studied. The results showed that chlorophyll content,Pn,Gsand E was decreased significantly in rice under nitrogen deficiency. Root-shoot ratio and Ciwas higher than that of control. Nitrogen deficiency had some effects on chlorophyll biosynthesis. The Pnof rice was decreased significantly. Dry matter accumulation was decreased significantly. Rrice root-shoot ratio was improved. Nitrogen was one of the necessary element for rice growth. The results will provide theoretic basis and technical approach for nitrogen use.
