Comparative study on six families ofSloanea hemsleyanabased on photosynthesis characteristics
By taking six families ofSloanea hemsleyana as the tested materials, theirs four kinds of photosynthetic parameters were and monitored and measured, the photosynthetic characteristics of different families were comparatively studied through continuous monitoring in order to provide theoretical basisfor the selection and protection ofS. hemsleyana superior family. The studying results show that there were signiifcant differences of net photosynthetic rate (Pn), transpiration rate (Tr), stomatal conductance (Gs), intercellular CO2 concentration (Ci), chlorophyll total content (Ct), the ratio of chlorophyll-a to chlorophyll-b (Ca/Cb); theGs andTr had signiifcant positive correlation withPn. theCi had asigniifcant negative correlation withPn; there were abundant genetic variations ofS. hemsleyana photosynthetic characteristics among the six families. Comparatively considering all the factors, the no.3 family is the bestone among the selected families.
