| 摘 要： | 油菜净同化率是衡量油菜光合能力的重要指标。油菜产量是由群体生长状况决定的 ,油菜高产群体净同化率的变化规律是油菜高产栽培研究的理论基础。研究表明 ,各生育阶段群体净同化率变化与个体相似 ,越冬期最低 ,越冬前后各有 1个高峰期 ,但个体净同化率的峰值越冬后显著高于越冬前 ;而群体的净同化率越冬前后高峰峰值基本一致 ,且延续时间较长

| Abstract: | The net assimilating rate of the rape seed is the important index of pholosynthetic capacity.Studies showed that the change of assimilating rate in each bear stage between individual and population was similar,the lowest was in the winter,and two peak periods were before and after winter.The individual's peak value of net assimilating rate was higher after than befove winter.And peak value of the net assimilation rate of the population unanimous basically before and after the winter, and extended time longer. |
