| Abstract: | The morphology and nutrition were compared between the short catkin sport and the original tree.The results showed that:the length of sport catkin was 2.2 cm,significantly shorter than the contrast(14.0 cm),the leaves of sport was greater,and the vigor of growth branch and bearing-fruit branch was higher than that of contrast.The energy substance such as sugar,protein and chlorophyll in sport leaves and catkins had a high level,while the sugar level was lower in contrast. |
