| 摘 要： | 选用4个小麦品种(系)分别代表大、 小粒品种， 研究了去除顶端两个小穗对植株光合速率、 14C同化物分配和穗部性状的影响。 去除顶端两个小穗后， 小粒品种(鲁麦14、 山农48—2)于灌浆中、 后期的光合速率提高， 大粒品种(鲁215953、 核生2号)则表现为降低； 灌浆初期14CO2的标记测定结果显示， 分配到穗部的14C同化物因去除

| Abstract: | Four cultivars representing large and small kernel size cultivars were used in this study. The effects of removal of the top two spikelets on photosynthetic rate, distribution of 14C assimilate and ear traits were investigated. When the top two spikelets were removed, the photosynthetic rate of the |
