摘要
对小麦与绿豆冠层冷温现象的研究表明,小麦与绿豆冠层冷温现象的显著特征是小麦和绿豆中某些基因型材料冠层温度持续偏低,且不因年份更迭和天气的变化而异,具有很高的稳定性。与植株的冷温相伴随,一些重要生物学性状如叶片功能期、叶绿素和蛋白质N含量、超氧化物歧化酶活性和净光合速率等也较冠层温度持续偏高的基因型材料明显为佳,这为进一步提高产量奠定了坚实的代谢基础。小麦与绿豆的亲缘关系很远,但共同的冷温特性使它们之中的某些基因型材料在一些重要生物学性状上具有相通的特性,且有利于作物生产能力的提高。
The low temperature phenomena of wheat and mungbean canopy were studied. The results show that the germplasm materials in wheat and mungbean have a persistent low canopy temperature, and their temperature type of the materials does not change whatever year and whatever kind of weather. Some important biological traits of the low temperature materials, i. e. the functional periods of the leaves, chlorophyll contents, protein nitrogen contents, SOD activities and net photosynthetic rates, are more excellent than those of the high temperature germplasm materials and all these can provide a solid ecological and physiologic basis to obtain high and stable yield. The low temperature materials in wheat and mungbean have a common characteristic with the excellent biological traits though the blood relationship of wheat and mungbean is very far, which is beneficial to the improvement of crop＇s productivity.
