| Abstract: | The experiment result indicated that the contribution of different branches to Chinese cabbage yield was the second branch>first branch>third branch>main stem. There was a positive co-relationship between single plant yield and the number of branches, the number of pods/plant. The number of branch was main factor in yield components. The increasing number of first and second branches before over-wintering was the key technique, which resulted in the increase of 30% of yield and 10% of 1000-seed weight. |
