Abstract: | Rhodiola sachalinensis growing in the different habitats, Xiaotianchi plot (altitude 1800 m), Tree line plot (altitude 2000 m) and Tianwenfeng plot
(altitude 2325 m), of Changbai Moutain (northern slop) were transplanted to Harbin Experimental Forest Farm for measuring
its characteristic of gas exchange. The study results indicated that the growth state and gas exchange characteristics ofRh. sachalinensis growing in different habitats varied markedly. The plants transplanted from Tianwenfeng plot had the highest values in net
photosynthesis rate (Pn) and transpiration rate (Tr), those transplanted from Tree line plot shows the second, and those transplanted
rom Xiaotianchi plot had the lowest values. The variance existed in transplanted plants was the same as shown in the field.
From the result it can be extrapolated that the difference of Pn and Tr existed inRh. sachalinensis transplanted from different habitats is depend not only on the environmental factors, but on the variance of physiological
characteristic of plant itself.
This study is supported by Natural science Foundation of Heilongjiang Province.
