| 摘 要： | 为探究银杏在北回归线以南、温度较高的环境下的生长规律及存活情况,于珠海市斗门区对67株银杏进行引种驯化实验研究。分析引种驯化环境因素,并对银杏进行为期3年的性状测量和物候期观测。研究结果显示,银杏3年存活率为80.6%,存活植株的健康率为40.7%,整体表现良好。大部分个体叶片受温度气候的影响较大,无法在秋冬季节正常黄化,但观察到14.9%个体生长情况表现良好,显示出较强的适应性和景观性。通过对银杏的引种驯化实验,揭示了银杏在珠海地区的生长规律,可为探究银杏对高温等环境的适应性及生长规律提供参考。

| Abstract: | To explore the growth pattern and survival of Ginkgo biloba in a high temperature environment in the south of the Tropic of Cancer, this study conducted an experiment about the introduction and domestication of 67 G. biloba plants in Doumen District of Zhuhai City. The environmental factors of introduction and domestication were analyzed, and 3-year character measurement and phenological observation of G. biloba were carried out. The results showed that the 3-year survival rate of G. biloba was 80.6%, the health rate of the surviving plants was 40.7%, and the performance was good as a whole. Most of the leaves were greatly affected by temperature and climate, and cannot normally turn yellow in autumn and winter. However, 14.9% of the individual plants had relatively good growth performance, showing strong adaptability and landscape characteristics. Through the introduction and domestication experiment, this study revealed the growth pattern of G. biloba in Zhuhai. The study can provide certain reference for exploring the adaptability and growth law of G. biloba under high temperature environment. |
