摘　　要：通过盆栽试验,将12份茄子(Solanum melongena L.)材料幼苗种植于镉污染的土壤中,研究了不同茄子材料在幼苗期和花期的生物量以及镉积累特性。结果表明,不同茄子材料间的生物量和镉含量均存在明显差异。当茄子处于苗期时,材料XN-Z1-2根系、茎秆、叶片及地上部生物量均较高,而材料“43-1”则相对较低;XN-Z1-2各器官镉含量较低,而“43-1”各器官镉含量均最高。当茄子处于花期时,材料“96-2”各器官的生物量整体上较高,而“43-1”各器官生物量均最低,各器官镉含量最高,而材料ZF-Z1-2各器官镉含量总体上较低。“43-1”是一种高镉积累的茄子材料;XN-Z1-2和ZF-Z1-2生物量较高,且镉积累量较低,是低镉积累的茄子材料,能够在镉污染的环境中正常生长。Twelve eggplant(Solanum melongena L.)materials were planted in cadmium-contaminated soil by pot experiment to study the biomass and cadmium(Cd)accumulation characteristics at the seedling and flowering stages.The results showed that there were obvious differences between eggplant materials on biomass and Cd content.The biomass in root,stem,leaf and shoot of the material XN-Z1-2 were all higher,while that of the material“43-1”was relatively lower;the Cd content of different organs of material XNZ1-2 was lower but that of the material“43-1”was all the highest when eggplant was at the seedling stage.Overall,the biomass of each organ of the material“96-2”was higher and that of the material“43-1”was the lowest;the Cd content was the highest in various organs of the material“43-1”and generally lower in the material ZF-Z1-2 if eggplant was in the flowering stage.In conclusion,“43-1”was a kind of eggplant material with high Cd accumulation;the material XN-Z1-2 and ZF-Z1-2,all possessed higher biomass and lower Cd accumulation,were eggplant materials with low Cd accumulation which could grow normally in Cd-contaminated soil.
