摘要: [Objective] The experiment aimed to research the photosynthetic characteristics of Calophyllum inophyllum Linn.and the relations between Calophyllum inophyllum Linn. and ecological factors.[Method] The portable photosynthesis system(Li-6400) was used to determine photosynthetic characteristics of 6-year-old Calophyllum inophyllum Linn.[Result] Both the leaf net photosynthetic rate change and diurnal variation of transpiration rate were single peak type.The relations among the leaf net photosynthetic rate of Calophyllum inophyllum Linn.and photosynthetically active radiation,CO2 concentration and other relevant ecological factors(including transpiration rate, stomatal conductance, difference of vapour pressure and leaf temperature) were two quadratic linear relations.[Conclusion] Calophyllum inophyllum Linn. preferred strong light irradiation and high temperature environment and the experiment has provided foundations for ecological and commercial cultivations.
