摘要：

A research was conducted to compare the photosynthetic rates and growth conditions of four types of Atractylodes lancea. A. lancea was divided into four types according to leaf morphology: the saw-tooth-leaf, the ellipse-leaf, the long-ellipse-leaf and the sharp-leaf. The photosynthetic rates of four types of A. lancea were determined by the portable photosynthetic instrument LI-6400 in the natural environment. Parameters such as stem width, stem height, leaf area of single plant of aboveground parts were measured periodically. The results showed that the photosynthetic rates of four types of A. lancea were 20.2 micro mol/(m2 s) for the saw-tooth-leaf, 18.96 micro mol/(m2 s) for the ellipse-leaf, 15.6 micro mol/(m2 s) for the long-ellipse-leaf and 17.6 micro mol/(m2 s) for the sharp-leaf, respectively. The photosynthetic rate of the saw-tooth-leaf was higher than those of the other three types. The growth rate of the saw-tooth-leaf was the highest in all four types at the 0.01 level. The research provided certain theoretical bases for further research on A. lancea.
