摘要：

为明确结荚后不同绿豆品种叶片光合、根系伤流特性及其与产量关系，以‘吉绿8号’、‘吉绿9号’、‘吉绿12号’、‘吉绿17号’和‘吉绿20号’5个吉林省主要种植的绿豆品种为材料，在绿豆产量形成的关键时期结荚期（R4期）测定叶片光合相关参数、根系伤流特性，在成熟期测定产量。结果表明，不同绿豆品种叶片光合、根系伤流特性和产量存在差异，‘吉绿12号’和‘吉绿9号’叶片的净光合速率、气孔导度、胞间二氧化碳浓度、蒸腾速率、根伤流液伤流强度、伤流液中可溶性蛋白含量及强度、可溶性糖含量及强度、游离氨基酸含量及强度、产量较高，显著高于‘吉绿8号’、‘吉绿17号’和‘吉绿20号’，其中‘吉绿12号’和‘吉绿9号’各指标之间的差异较小。绿豆的产量与叶片光合能力和根伤流中的组分及含量呈正相关关系。不同绿豆品种的产量与叶片光合和根伤流特性密切相关，叶片净光合速率和根伤流强度可作为选育高产绿豆品种的指标。

Abstract:

The paper aims to clarify the characteristics of leaf photosynthesis and root injury flow characteristics of different mung bean varieties after pod formation and their relationship with yield. This experiment used five mung bean varieties mainly planted in Jilin Province, namely ‘Jilv 8’, ‘Jilv 9’, ‘Jilv 12’, ‘Jilv 17’ and ‘Jilv 20’, as materials. The leaf photosynthesis-related parameters and root damage characteristics were measured at the pod-setting stage (R4 stage), a critical period for mung bean yield formation, and the yield was measured at the maturity stage. The results showed that there were differences in leaf photosynthesis, root injury characteristics, and yield among different mung bean varieties. The net photosynthetic rate, stomatal conductance, intercellular carbon dioxide concentration, transpiration rate, root exudate intensity, soluble protein content and intensity, soluble sugar content and intensity, free amino acid content and intensity, and yield of leaves of ‘Jilv 12’ and ‘Jilv 9’ were relatively high, significantly higher than those of ‘Jilv 8’, ‘Jilv 17’and ‘Jilv 20’. The differences in various indicators between the mung bean varieties ‘Jilv 12’ and ‘Jilv 9’ were relatively small. The yield of mung beans was positively correlated with the photosynthetic capacity of leaves and the components and content in root sap. This experiment shows that the yield of different mung bean varieties is closely related to leaf photosynthesis and bleeding characteristics.
