摘要： Cuttings are asexual reproduction, and different vegetative organs of the plant can be selected as cuttings to grow into a new plant. Growth and cadmium (Cd) accumulation of cuttings taken from tomato (Solanum lycopersicum) plants non-grafted or grafted onto five different rootstocks were studied in a pot experiment. 'Zhongyanhong 6MODIFIER LETTER PRIME and 'Hongyu F1MODIFIER LETTER PRIME were non-grafted (CK) and were grafted ontoSolanum torvum, Totosga, 'Dalishengen', 'Banzhen 18MODIFIER LETTER PRIME and 'Guozhen 1MODIFIER LETTER PRIME, respectively, planted in pots without Cd-contaminated soil. Cuttings were taken after one month, then grown in Cd-contaminated soil (10 mg kg(-1)) for three months. In 'Zhongyanhong 6MODIFIER LETTER PRIME cuttings, compared with non-grafted, grafting onto five rootstocks increased plant dry weight, grafting onto 'Banzhen 18MODIFIER LETTER PRIME andS. torvumincreased plant height, grafting onto 'Banzhen 18MODIFIER LETTER PRIME and 'Guozhen 1' increased fruit fresh weight, grafting onto 'Guozhen 1MODIFIER LETTER PRIME and 'Dalishengen' reduced Cd content in fruit. In 'Hongyu F1MODIFIER LETTER PRIME cuttings, compared with non-grafted, grafting onto five rootstocks increased plant dry weight, grafting ontoTotosgaincreased plant height, grafting ontoS. torvumandTotosgaincreased fruit fresh weight, grafting onto 'Banzhen 18MODIFIER LETTER PRIME, 'Dalishengen',S. torvumandTotosgadecreased Cd content in fruit. Cutting after grafting affects growth and Cd accumulation of tomato, which can provide a theoretical basis for the safe production of nightshade vegetables.
