| 摘 要： | 分析了金钟藤(Merremiaboisiana(Gagn.)vanOoststr.)的年轮特征,并探讨了它与温度等气候因子的关系。金钟藤的年轮极不规则,有许多自然隆起和裂缝。金钟藤的年轮生长量通过格子法来估算。结果表明金钟藤年轮的年平均生长量与温度呈极显著正相关,与降水、日照时数和相对湿度相关性不显著。罗浮山地区降水和日照时数基本能够满足金钟藤的生长,结合相关研究结果推测:温度可能是金钟藤快速生长的主要驱动因子。 |

| Abstract: | The characteristics of annual ring of Merremia boisiana (Gagn.) van Ooststr. and the relationship between mean annual ring growth and climatic factors including temperature, precipitation, relative humidity, and sunshine time were studied in this paper. With characteristics of asymmetric, nature cracks and asymmetric uplifts, annual rings were clearly observed only near the center of the discs. Grid method was used to analyze the ring growth of Merremia boisiana. Results showed that there was significantly positive correlation between average annual ring growth and temperature, while no significant relationship were found between average annual ring growth and other referred factors. In conclusion, temperature may be the main driving force for the rapid growth of Merremia boisiana; precipitation and sunshine time were not limited factors in Luofu Mountain area. |
| Keywords: | Merremia boisiana annual ring radial growth climatic factor |
