1 Light green, elliptical, very thin, long flexible petiole. Usually single crown. Large..亮绿色椭圆型很薄的叶子，长而有弹性的叶柄。通常单个顶芽。大型。

2 In long shoot, the leaf width, leaf length, leaf area, petiole length and basal angle decreased, but the leaf index and the ratio of lobation increased as its arrangement increased..一年生长枝叶片的叶宽、叶长、叶面积、叶柄长、叶基角均随叶序的增加逐渐减小，叶形指数和有缺刻叶的比例则增加。

3 The basic medium, choice of node petiole explants, plant growth regulator concentration and variety all affected the induction of somatic embryos and the regeneration of adventitious buds..结果表明，体胚的诱导和不定芽的再生与基本培养基、叶柄的着生部位、生长调节物质种类和浓度等因素有关。
