Growth regularity and the effect of climatic factors on Tamarindus indica.
Tamarindus indica Linn, an evergreen arbor, belongs to Caesalpiniaceae, were introduced to China recently, and it is a tropical non-wood forest with high edible and medicinal value. In this paper, relevant data of its growth and climatic factors were collected based on regional trials, and its growth rhythm and the effect of climatic factors were analyzed. The results showed that the growth curve of basal diameter, high and crown width were in a "s" shape. Its growth accorded with the Rogistic growth model and the process of reproductive development. There were significant difference in growth rate among different experimental sites, and the mean temperature and accumulated temperatures above 10°C were the main impact factors of its high and basal diameter respectively, and heat should be considered as the critical factor in its planting for promoting.
