| 摘 要： | 为了研究超高产小麦品种冠层结构时产量的影响,以鲁原301、潍麦8号和山农62G三个超高产小麦新品种(系)和对照品种鲁麦14为材料,采用"大田切片法"研究其在生育后期的冠层结构和产量变化.结果表明,与鲁麦14相比,三个超高产小麦品种(系)在生育后期旗叶、倒二叶和倒三叶都具有较高的光合速率,而且各品种下层的叶面积指数、群体的透光率和光能利用率明显高于鲁麦14;鲁原301、潍麦8号和山农62G品种的产量分别比鲁麦14提高8.6%、17.0 %、16.7%,差异均达到显著水平.说明超高产小麦具有较合理的群体结构,有利于叶片对光能的吸收、保持群体中下部叶片较高的光合能力、积累更多的有机物质,最终提高籽粒产量. |
| 关 键 词： | 超高产小麦 生育后期 冠层结构 光能利用 籽粒产量 |

| Abstract: | Three super-high yield wheat cultivars of Luyuan 301,Weimai 8 and Shannong 62G were used as materials to study crown layer leaves and yield structure using the conventional "Layer upon layer cut method".The results showed that Pn of flag leaf,second leaf and third leaf from top at late growth period of three super-high yield wheat cultivars was higher than that of Lumai14.Population transmittance,leaf area index of underlayer and solar energy use efficiency of three super high yield wheat cultivars were als... |
