项目摘要

GA promoted early growth of mulberry, but in the later stage, photosynthetic activity of mulberry leaves and dry matter growth was depressed.TIBA induced higher destribution of stomata to upper leaves and inhanced photosynthetic activity. In the case of prunned mulberry, regrowth of new leaves and stems were promoted.Morphactin inhanced the chlorophyll content of mulberry leaves, but malformed leaves such as fused ones at the uppermost region of stem appear ed. In the treated plot, inhancement of Zn content and fall of K content were induced. Brassinolide promoted growth of mulberry leaves and stems in the earlier growth period. It induced inhancement of Zn content and fall of K content of mulberry leaves, too.It is necessary to be careful for the use of morphactin and brassinolide not to induce damage by K deficit and Zn excess.

赤霉素对桑树早期生长有促进作用，但对后期桑叶光合活性和干物质生长有抑制作用。TIBA提高了气孔向上部叶片的分布，提高了光合活性。在修剪桑树的情况下，促进了新叶和新茎的再生。Morphactin可提高桑叶叶绿素含量，但在茎上部出现融合叶片等畸形叶片。处理区诱导Zn含量升高，K含量下降。油菜素内酯对桑叶和桑茎生长有促进作用。对桑叶锌含量的提高和钾含量的下降也有一定的促进作用。在使用morphactin和芸苔素内酯时要小心，以免引起钾亏缺和锌过量的损害。
