- Abstract
The effects of mutual grafting on the photosynthesis of two ecotypes of post generation Solanum photeinocarpum under cadmium (Cd) stress were studied by the pot experiment, and the photosynthetic pigment contents, photosynthetic characteristics and soluble sugar contents in post generations of S. photeinocarpum were determined. Under Cd stress, two ecotypes of S. photeinocarpum mutual grafting improves the chlorophyll a, chlorophyll b, total chlorophyll and carotenoid contents of their post generations. The mutual grafting increased the net photosynthetic rate (Pn), transpiration rate (Tr), stomatal conductance (Gs), CO₂ concentration of intercellular (Ci) of post generations of S. photeinocarpum, and decreased the value of pressure deficit leaf (Vpdl) of that compared with the un-grafted control, respectively. Compared with the un-grafted control, the grafting increased the soluble sugar contents in roots, stems, leaves and shoots of post generations of S. photeinocarpum. Therefore, two ecotypes mutual grafting could improve the photosynthesis of post generations of S. photeinocarpum under cadmium stress.
