In order to understand the growth of Oxytenanthera abyssinica introduced from Ethiopia in Africa, the photosynthetic physiolgical ecology characters of two-year-old seedlings planted in Zhanjiang, Guangdong Province, China were studied. The results showed that the Chl a/b value was about 2.3∶1, the high Chl b content indicated that O. abyssinica had a certain tolerance of shade. When the light intensity ranged from 800 to 1600 μmol m-2s-1, the photo-inhibition of O. abyssinica was not appeared, showing strong light adaptability. There were good correlation between phenotypic traits and eco-physiological traits. According principal compenent analysis, the four factors, such as Chl b, ФPSⅡ, Chl a and Fo, were principal components, their accumulated variance contribution rate was up to 86.89%. The all seedlings were divided into four types by the cluster analysis. Therefore, there were significant differences in phenotypic and eco-physiological characters among O. abyssinica individuals, which would be provided with morphology and physiological basis in genetic breeding.
