| Abstract: | Through analysing the effect of accumulated temperature and light during the growing period on hybrid rice agronomic characteristics,it is learned that the magnitude of the effect of accumulated temperature on each agronomic characteristic was in such an order as empty seed percent>yield>1000 grain weight>effective ears>plant height>seeds of per ear,the magnitude of the effect of light on each characteristic was in the order of 1000 grain weight>seeds of per ear >plant height >effective ears>empty seed percent>yield.The regression equation of temperature and light to yield is =-112.950+0.4498X 1+0 0121X 2. |
