| 摘 要： | 研究了外源赤霉素处理对山蒌植株生长的影响，结果表明：赤霉素处理可促进山蒌植株茎伸长，以80 mg/L获得最佳效果；40、20 mg/L赤霉素处理7次后，对茎粗的增加效应最强。赤霉素处理虽然不能增加叶片数，但40 mg/L可最大程度地促进叶面积指标增大。

| Abstract: | In order to obtain the effective method of increasing the leaf production of Piper sarmentosum Roxb. by gibberellin (GA) stimulation, study on the effects of exogenous GA treatment on the growth of plants P. sarmentosum was carried out. The results showed that GA spraying could promote stem elongation, with the optimum concentration of 80 mg/L; Treatments with 40 mg/L and 20 mg/L GA had the strongest stimulating effect on stem diameter growth. GA treatment had no apparent effect on increasing the number of leaves, but 40 mg/L GA could significantly increase the area index of leaf length ×leaf width. |
