Abstract
The aim of this pot experiment was to determine the grafting affecting the physiology of two Solanum photeinocarpum ecotypes under selenium (Se) stress. Two S. photeinocarpum ecotypes (farmland and mining) were subjected to mutual grafting, and then their physiological characteristics were determined after growth in soil containing Se at 10 mg kg−1. Compared with ungrafted S. photeinocarpum, the combination of the scion (farmland ecotype) and the rootstock (mining ecotype) showed increased photosynthetic pigment contents, while the opposite grafting combination showed decreased photosynthetic pigment contents. Mutual grafting also increased the antioxidant enzyme activity grafted S. photeinocarpum, and these parameters showed the highest values in the combination of the scion (farmland ecotype) and the rootstock (mining ecotype).
