Abstract: Based on the general investigation and analysis of the ancient trees of Ficus microcarpa at Gulangyu by use of the growth indices and the physiological indices, such as the growth status of annual branches, leaves and fruits and the chlorophyll fluorescence, the diagnosis of the ancient trees of Ficus microcarpa with different growth vigor was discussed to provide evidence for their maintenance and rejuvenation.The results indicated that the growth indices and the physiological indices could consistently instruct the health status of the ancient trees of Ficus microcarpa.Thus the diagnosis by the combination of the growth indices and the physiological indices could be applied to the ancient trees of Ficus microcarpa.

Key words: Ficus microcarpa, diagnosis, growth index, physiological index

摘要： 通过对鼓浪屿古榕树的普查,选择其健康诊断的生长指标和生理指标,包括当年生枝叶、果实生长状况、叶绿素荧光等,对不同生长势的古榕树进行分析,旨在探讨基于生长指标与生理指标相结合的古榕树的健康诊断方法,为古榕树的养护与复壮提供依据。结果表明,生长指标与生理指标能较一致地指示古榕树的健康状况。因此,可通过生长指标与生理指标相结合的方法诊断古榕树的健康状况。
