Abstract

A pot experiment was conducted to study the effects of grafting on photosynthetic characteristics of potential Cd-hyperaccumulator Solanum photeinocarpum under Cd stress. Four treatments were used in the experiment: ungrafted (UG), self-rooted grafting by the same S. photeinocarpum seedling (SG), self-rooted grafting by two different sizes of S. photeinocarpum seedlings (DG) and grafting on the rootstock of wild potato (PG). The results showed that SG and DG enhanced net photosynthetic rate (Pn) of S. photeinocarpum (Pn of DG was higher than SG), but PG decreased that. The light use efficiency (LUE) was the same as Pn. The grafting treatment decreased transpiration rate (Tr), stomatal conductance (Gs) and CO2 concentration of intercellular (Ci) of S. photeinocarpum, and increased water use efficiency (WUE) of S. photeinocarpum. Therefore, grafting could use to enhance the photosynthetic ability of Cd-hyperaccumulator S. photeinocarpum for the phytoremediation.
