对谷子根部性状的遗传及根的地下分布研究结果表明,成熟期高秆、矮秆材料的根重、根伤流液大小均是受遗传控制的性状。高秆材料的根条数明显地高于矮秆材料。谷子的根部性状与产量及与产量关系密切的性状之间存在着相关关系。根条多、根重大、后期根伤流液大小适中对植株的产量及产量相关性状的形成非常有利。根系大、在耕作层的分布范围广、后期根活力大、不早衰是高秆材料在产量上明显优于矮秆材料的主要原因。
The research on the inheritance of root traits and underground distribution of millet showed that the root weight and the size of the fluid in root exudates were genetically controlled in mature stage. The number of stalks was significantly higher than that of dwarf stalks. There is a correlation between the root traits of millet and traits related to yield and yield. Roots and more, a significant root, the late root canal fluid size is moderate on the yield and yield-related traits of the formation of very favorable. The root system is large, the distribution area in the tillage layer is wide, the root vigor is great in the later period, and the premature premature decline is the main reason why the high-stalk material is obviously superior to the dwarf material in yield.
