【 摘 要 】

To a certain extent, leaf sugar content shows the plant growth status. At the beginning of the rapid growth of the seedlings of soybean, internal physiological indexes, such as the correlation between sugar content and external apparent growth is not very clear. This experiment measured the soybean seedling stage in different gradient of the soluble sugar content and the correlation of the apparent growth indicators, including leaf weight, leaf width, leaf length, root length, number of radicle, etc. The correlation between soluble sugar content and the apparent growth studies to preliminary discussion on this issue is analyzed. The data shows that in the seedling stage, leaf soluble sugar content increase quickly, and the apparent growth has different correlation with indicators. The weight of leaf has a intimate relativity with soluble sugar content, but leaf width and length have weaker correlation with it. And the root length and number of young root show little correlation with soluble sugar content. Experiment results indicate that in soybean seedling stage, internal physiological indexes do have a specific relationship with external growth index in some degree.
