摘　　要：利用以色列Phytech公司生产的Phytalk植物生理生态监控系统,对晚熟龙眼品种‘冬宝9号’果实成熟阶段枝梢直径、果实横径及气象因子进行了同步自动采集,并对其变化过程特征进行分析。结果表明,结果母枝与主枝日变化趋势一致,结果母枝对环境变化的反应较主枝敏感但变幅较小;果实成熟与枝梢生长间存在明显的竞争;日辐射、气温、空气湿度、饱和大气压差影响枝梢直径日变化。The data of meteorological parameters and shoot diameter and fruit transverse diameter of late longan variety ＂ Dongbao 9＂ were automatically recorded by using PM-11 Phytomonitor of PhyTalk produced by PhyTech, an Israeli company, in order to analyze the relation between the weather and the growth of shoot and fruit during the fruit maturity. The results showed that the bearing shoots had a similar daily variation tendency to the leader branches, and had a more sensitive response to environmental change although in a small degree than the leader branches, that there was a significant competitive relation between fruit and shoot growth, and that diurnal variation in shoot diameter was influenced by solar irradiance, air temperature and humidity, and saturated air pressure.
