title: Interspecies rootstocks affect cadmium accumulation in postgrafting generation plants of potential cadmium-hyperaccumulator Solanum photeinocarpum.
abstract: Pot and field experiments were conducted to study the effects of interspecies rootstocks on cadmium (Cd) accumulation characteristics of the potential Cd-hyperaccumulator Solanum photeinocarpum postgrafting generation plants. Four treatments (ungrafted and S. photeinocarpum seedlings grafted on the rootstocks of eggplant, potato, and tomato) were utilized in the present study. In the 2 pot experiments, eggplant and potato reduced biomass of S. photeinocarpum postgrafting generation plants, whereas tomato increased shoot biomass compared with the control (ungrafted seedlings). Compared with ungrafted seedlings, tomato increased and eggplant decreased Cd contents in shoots of S. photeinocarpum postgrafting generation. Only tomato increased Cd extraction by shoots of S. photeinocarpum postgrafting generation compared with ungrafted seedlings. In the field experiment, only tomato increased shoot Cd content of S. photeinocarpum postgrafting generation by 8.31% and shoot Cd extraction by 9.30% compared with ungrafted seedlings. Therefore, use of tomato as rootstock could enhance the ability of S. photeinocarpum postgrafting generation plants to remediate Cd-contaminated soil.
