| 摘 要： | 杜仲剥皮后,在暴露表面,分别涂以适当浓度的乙烯利、2,4-D、萘乙酸(NAA)和赤霉素(GA),以及 NAA GA 等植物激素,可看到不同的反应。发现用2,4-D、GA 和 NAA处理的,木栓形成层和维管形成层的发生都早于对照,而用乙烯利处理的,只是木栓形成层的发生提早。只有用 NAA 处理的,木栓形成层和维管形成层的发生都与对照相似。

| Abstract: | When the exposed surface of the girdled trunk of Eucommia ulmoides Oliv.were daubed with plant hormones,i.e.ethrel,2,4-D,NAA,GA and NAA GA respectively in appropriate concentrations,it was found that the 2,4-D,GA and NAA GA treated trunks,initiations of phellogen and vascular cambium in callus were ear- lier than that in control.These trunks treated with ethrel,formation of phellogen alone were earlier.However,initiation of phellogen and differentiation of vascular cambium in the trunk treated with NAA were similar to control. |
