Abstract
The physiological characteristics of root and flag leaf in two hybrid rice, Ho nglianyou 6 and Liangyou 1193, after flowering stage under different irrigation patterns were studied. Root density and activity were higher under controlled damp irrigation than those of submerged irrigation. Chlorophyll contents in f lag leaf under controlled damp irrigation were not different at flowering stage, but distinctly higher at mature stage compared with that under submerged irriga tion. Net photosynthetic rate of flag leaf under controlled damp irrigation also significantly higher than that of submerged irrigation at reproductive stag e. Compared with submerged irrigation, two hybrid rice combinations had higher community growth rate(CGR) and relative growth rate(RGR), and obtained higher g rain yield under controlled damp irrigation. The higher yield might result fr om enhancement of the dry matter accumulation favorable to the grain developmen t at reproductive stage under controlled damp irrigation.
