| 摘 要： | 选用不同叶片姿态、不同叶片类型以及不同经济系数等多种特性小麦品种(品系)以及拟近等基因系为试验材料,测定了不同叶位叶面积、旗叶光合速率以及小麦生物和经济产量。研究小麦叶面积、旗叶光合速率与产量的关系。结果表明:顶三叶面积与单株生物产量、经济产量显著正相关,而下部三片叶叶面积与单株生物产量和经济产量之间无显著相关;旗叶光合速率与生物产量和经济产量之间呈正相关,但相关不显著,而旗叶光合速率与旗叶面积的乘积与生物产量和经济产量之间呈显著正相关。提高小麦顶三叶面积和光合速率有利于提高产量,旗叶面积和光合速率乘积与产量的关系更为密切。

| Abstract: | In order to investigate the relationships among leaves at different positions,photosynthetic rate of flag leaf and grain yield,thirty-three wheat varieties(lines) which have differences among leaf characteristics,harvest index and yield were studied as materials.The results indicated that the correlations between the top-three leaf area and single plant biomass,economic yield were significantly positive.However,there were no significant correlation between the area of other leaves located on the base positi... |
