| 摘 要： | 为了研究大豆品种的推广种植潜力，以‘东农252’、‘黑农48’、‘黑农35’、‘黑农34’4个大豆品种为材料，在短日照条件下，分析各大豆品种的株高、单株荚数、叶面积、根干重等农艺性状。结果表明：短日照显著降低4个品种大豆的株高、叶面积、根干重，除‘东农252’外，也显著降低了单株荚数。大豆品种差异极显著影响株高性状的短日照敏感性，对单株荚数、叶面积、根干重性状影响不显著。性状差异极显著影响‘东农252’、‘黑农48’的短日照敏感性，显著影响‘黑农34’的短日照敏感性，对‘黑农35’影响不显著。各性状的短日照敏感性差异为根干重＞叶面积＞株高＞单株荚数。相对其他大豆品种，‘东农252’各农艺性状短日照敏感性最强。4个大豆品种的短日照敏感性差异与其种植范围大小基本一致。本研究为评估大豆品种推广种植潜力提供参考。

Planting Promotion Potential of Soybean Varieties: Based on Short Sunshine Conditions |
| |
| Abstract: | To study the promotion planting potential of soybean varieties. Taking 4 soybean varieties (‘Dongnong 252’, ‘Heinong 48’, ‘Heinong 35’, ‘Heinong 34’) as materials, we analyzed the agronomic traits of each soybean variety, such as plant height, pod number per plant, leaf area, root dry weight and so on based on short sunshine conditions. The results showed that: short sunshine significantly decreased plant height, leaf area and root dry weight of 4 soybean varieties, and significantly reduced the pod number per plant except for ‘Dongnong 252’; the differences of soybean varieties significantly affected the short sunshine sensitivity of plant height traits, but had no significant effects on pod number per plant, leaf area and root dry weight; the differences of traits very significantly affected the short sunshine sensitivity of ‘Dongnong 252’, ‘Heinong 48’, and significantly affected the short sunshine sensitivity of ‘Heinong 34’, but had no significant effect on ‘Heinong 35’; the differences in short sunshine sensitivity of each trait was root dry weight>leaf area>plant height>pod number per plant. ‘Dongnong 252’ was the most sensitive to short sunshine compared with other soybean varieties. The short sunshine sensitivity differences of 4 soybean varieties were basically the same as the planting range. This study provides a reference for assessing the promotion planting potential of soybean varieties. |
