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。

The higher the precipitation, the greater the root depth, total root length and root diameter, the more lateral roots and the lower ratio of root to shoot.

降雨量越大，根系越深、总根长越大、根系直径越大、侧根越多、根冠比越低。

Shoot tip culture in the most important factor is the impact of the cut tip size, tip length is less than the general requirements of 1mm.

茎尖培养中最主要的影响因素就是切取茎尖的大小，一般要求茎尖长度小于1 mm。
