摘要
以中粒小麦 4 185为对照品种 ,研究了不同大粒小麦品系在灌浆至成熟期间的光合性能、灌浆强度及最终的产量 .结果表明 ,大粒小麦的叶面积大 ,光合速率高 ,灌浆强度高 ,千粒重明显高于中粒品系 。
Contrast with medium kernel breed 4185,we studied photosynthesis,filling rate and yield of big kernel wheat during filling and riping stages. The conclusion was that big kernel wheat's leaf areas were bigger,photosynthesis rates and thousand kernel weights were higher than medium kernel wheat.So the big kernel breeds should be popularized.
