Abstract

The effects of cutting after continuous grafted on the photosynthesis physiology of Lycopersicon esculentum seedlings under cadmium (Cd) stress were studied by the pot experiment, and the photosynthetic pigment contents, photosynthetic characteristics and soluble sugar content of L. esculentum seedlings were determined. Under Cd stress, continuous grafting decreased the chlorophyll a, chlorophyll b, total chlorophyll and carotenoid contents of L. esculentum seedlings with Cyphomandra betacea compared with the un-grafted plants (CK). The one-grafted (G1), two-grafted (G2) and three-grafted (G3) decreased the net photosynthetic rate (Pn), transpiration rate (Tr), stomatal conductance (Gs), CO2 concentration of intercellular (Ci) of L. esculentum seedlings, and decreased the value of pressure deficit leaf (Vpdl) of that compared with CK. Compared with CK, the continuous grafting increased the soluble sugar contents in roots, stems, leaves and shoots of L. esculentum seedlings. Therefore, cutting after continuous grafted is unfavorable for the growth of the L. esculentum seedlings under Cd stress.
