摘要
采取不同淹水时间与淹水深度的处理，研究了４个水稻品种在孕穗期叶片中的碳、氮含量及其光合速率．结果表明：经淹水处理后，水稻叶片的光合速率和总糖含量及ｃ／Ｎ比均下降，而总氮含量上升，并且两个杂交稻品种对淹水处理的耐性较两个常规稻品种强．
The carbohydrate coontent,nitrogen content and
photosynthetic rate in leaves of four rice va-rieties were studied,using different time and depth
Of submergenee treatments. The results showed that therewere decreases in total
carbohydrate content, photosynthetic rate and C/N rate in leaves of four rice vari-eties,but an
increase in total nitrogen content in leaves of these varieties. The resistance of hybrid
rice(V46and V48)to partial submergence was greater than that of conventional rice(Zaoxuan 32
and Zaoxuan 406)
