| Abstract: |
| Soybean root traits under three different densities were analysed. The results show that, root width, root volume, root dry weight and bleeding sap quantity were regular well within plough layer, overall, there's a trend that these root traits reduced with density increased. There were significant positive correlation between root width and root dry weight, roots width and roots volume, roots volume and root dry weight, bleeding sap quantity and root dry weight, bleeding sap quantity and root volume. Root dry weigh and root volume were the most simple and accurate indicators for evaluating root traits. |
