Comparative Study of Cypripedium Plant Photosynthetic Characteristics from Changbai Mountain

This study reports on extensive and in-depth investigations into the morphological, photosynthetic, physiological indices of 10 different types Cypripedium plant introduced from Changbai Mountain. It is an important prerequisite for ex situ conservation plants to provide new insights their photosynthesis. result can not only promote production vegetative but also with lots flowers characteristics promoting artificial introduction cultivation wild resources. A critical comparison results showed that high light intensity one causes reduction in photosynthesis samples. macranthum had most morphological advantages, while guttatum, smallest type, lowest morphogenesis. Photoinhibition began daily at 12:00 pm reached a second peak 14:00 all types. C. macranthum, ventricosum, calceolus greater photosynthetic capacity than other Using principal component analysis, order was CCMY > CVPP CCRY CMPP CVRR CSPY CMWW CMLL CMDD CGWW. These lay groundwork future research resource distribution conservation.
