【摘要】 [Objective] To investigate the effects of different light conditions on the growth and photosynthetic characteristics of Sanicula lamelligera Hance. [Method] One-year-old sowing seedlings of S. lamelligera were transplanted in 5 different site conditions, including bamboo forest, metasequoia forest, forest edges and open space. Three years later, the growth indexes and physiological indexes of plant leaves were measured. [Result] S. lamelligera plants grew well to the east of metasequoia forest, in open space and in bamboo forest with larger leaf area index and higher net photosynthetic rate and grew commonly in metasequoia forest with smaller leaf area index and lower net photosynthetic rate. But to the west of metasequoia forest, the growth of S. lamelligera was inhibited with the minimum leaf area index and higher net photosynthetic rate. [Conclusion] S. lamelligera is a kind of typical undergrowth vegetation growing close together under trees in woods and forests, which is suitable to be planted in ventilated and euphotic land parcels to the east of metasequoia forest.
