Abstract: The natural growth of three native lianas, Artabotrys hexapetalus, Mussaenda pubescens and Parthenocissus dalzielii, were observed and measured in the field to explore the annual growth of plants and branches as well as their garden application in Guangzhou. The results showed that the branch growth of three lianas were all in accordance with the Logistic growth model, and the fitting decision coefficients were 0.997, 0.992 and 0.997 respectively, which reached a very significant level (P<0.01), the validity and reliability of the parameters were guaranteed. In the annual cycle, the average monthly growth of branches of three lianas had a certain regularity, A. hexapetalus and M. pubescens had three growth peaks in March, June and September, P. dalzielii had two growth peaks in March and July. According to the phenological growth law, this paper discussed how to combine the phenological growth with the landscape application of lianas, and put forward suitable landscape application modes for three lianas, in order to achieve the formation of liana landscape purposes.

摘要： 通过对广州地区鹰爪花Artabotrys hexapetalus、玉叶金花Mussaenda pubescens、异叶地锦Parthenocissus dalzielii 等3种乡土木质藤本自然生长的定点观察和测量，探究其植株与枝条年生长规律及其园林应用特点。结果表明，3种木质藤本植物的枝条生长均符合Logistic生长模型，拟合决定系数分别为0.997、0.999和0.992，达极显著水平(P<0.01)，保证了所求参数的有效性和可靠性；在年生长周期中，3种木质藤本的枝条月均生长量具有一定的规律，鹰爪花、玉叶金花有3次生长高峰，分别在3月、6月和9月；异叶地锦有2次生长高峰，分别在3月和7月。根据物候生长规律，探讨将物候生长与木质藤本植物园林应用相结合，提出3种木质藤本适宜的园林应用方式，为营造良好的木质藤本景观提供参考。
