| 摘 要： | 小麦千粒重与平均净同化率和光合势呈极显著正相关（ｒ＝０．４１５＾＊，ｒ＝０．５０７＾＊），与平均灌浆速度，充实指数和穗下茎维管刺数量呈级显著正相关（ｒ＝０．６０４＾＊＊，ｒ＝０．８２９＾＊＊，ｒ＝０．６３５＾＊＊）。籽粒最大体积与平均净化同化率呈极显著正相关（ｒ＝０．８６８＾＊＊），与穗下茎维管束数量呈显著正相关（ｒ＝０．５２３＾＊）。充实指数与平均灌浆速度呈极显著正相关（ｒ＝０．８５２＾＊＊）。

| Abstract: | The results showed that correlation between wheat 1000-kernel weight with average net assimilating rate and photosynthetic power were significant respectively(r=0.415*,r=0.507*),and with average grain Pulling speed,Pulling index,vascular bundle No.under spike stem were very significant respectively(r=0.640**,r=0.829**,r =0.635**).The correlation between the max volume of grain and average net assimilation rate was very significant respectively(r=0.868**),and vascular bundle No.nuder spike stem was significance respectively(r=0.523*),and between fulling index and average grain fulling speed was very significant respectively(r=0.852**). |
