Chlorophyl l Fluorescence Characteristics Variation of Bleti l la striata in Spring
The chlorophyll fluorescence characteristics variation of rare medicinal plants Bletilla striata in spring were studied by using PAM-2500 to provide a theoretical reference for artificial cultivation of B.striata.The results showed that fluorescence parameters of B.striata had the same change trend in the three months of spring,significantly differences existed in the three months(P <0.05),and basically, values of fluorescence parameters in May>April>March.Trends of Fm and Fv/Fm in spring were similar to each other,which decreased first and then increased;ETR first increased and then decreased.
