Photosynthetic characteristics of Dendrobium officinale from five provenances

Abstract: To real photosynthetic characteristics variation of Dendrobium officinale from different provenances to provide reference for producing quality,low-carbon,and efficient D. officinale,photosynthetic rate and light intensity response curve of D. officinale provenances from Qingyuan,Tiantai,and Wuyi in Zhejiang Province,as well as Guangnan and Malipo in Yunnan Province were studied. Diurnal variation for the photosynthetic rate and light response curves for net photosynthesis to photosynthetic photon flux densities (PPFD) were measured using an Li-6400 photosynthetic determination system. Results showed that the net photosynthetic rate,the light saturation point,and the light compensation point in leaves of D. officinale were low with some differences (P<0.05) among the five provenances. Thus,during cultivation,light intensity must be controlled to ensure quality,low-carbon,and efficient production of D. officinale.[Ch,6 fig. 1 tab. 8 ref.]
