| Abstract: | The traits of new root formed in cutting aparts of mother beet root were investigated in this experiment. The result shown that there were 83% of new roots formed on the right side of cutting section, only 4.7% on the left side. All new roots formed from top to end along the vertical section of vascular bundle rings, we deem distribution of nutrients and plant hormone has apical dominance and right side dominance, and gave proper explanation on the root shape and curve and slanting of root gully. |
