Study on the Production and Transportation of Dry Matter of Erect and Curved Panicle Type Rice

A comparative analysis on the production and transportation of dry matter in different growth stages of erect panicle type rice and curved panicle type rice was conducted. The results showed that the filling degree of erect panicle type rice was significantly higher than that of the curved panicle type rice. The accumulation of dry matter of erect panicle type rice in vegetative growth stage was higher than that of the curved panicle type rice, and the output rate of two panicle type rice was the opposite. The contribution rate of dry matter accumulation after heading in two panicle type rice were more than 85%, and the contribution of erect panicle type rice was higher than that of the curved panicle type rice. The dry matter translocation rate of dry matter before heading of erect pani-cle type rice was lower than that of the curved panicle type rice.
