不同基因型大豆植株酰脲含量的动态规律

Study on dynamic regulation of ureides content in soybean plants among different genotypes

叶片和茎秆的酰脲含量除秣食豆外均呈现低-高-低的变化趋势。秣食豆叶片的酰脲含量呈现为“M”型曲线的变化趋势。秣食豆茎秆的酰脲含量呈现缓慢上升的趋势。荚皮酰脲含量东农42呈低-高-低变化,其他品种呈现为下降趋势。同一生育时期高蛋白品种东农42和黑农35各个时期酰脲含量都要高于高油品种东农46和垦丰9。同一生育时期营养器官之间的酰脲含量有较大差异。

The content of ureides took on low-high-low dynamic Changes in the leaves and stems in all experiment materials except the MSD. The dynamic changes of the content of ureides took on ＂M＂ in the MSD, and the content in stems increased gradually. The ureides content of pod shells had the low-high-low dynamic changes in DN42, while decreased in other varieties. The contents of uredies in DN42 and HN35 （high protein） were higher than that of DN46 and KF9 （high oil） in the same stages. The nutrition organs had much differences in the contents of uredies in the same stages.
