以番茄为实验材料，研究了29个番茄品种在盆栽条件下对不同质量分数Cd污染的差异吸收和累积情况．结果表明：（1）29个番茄品种可食部位Cd质量分数存在显著品种差异（P＜0.01），1.2和2.0 mg·kg-1 Cd处理下，番茄果实的Cd质量分数范围分别为0.037～0.134和0.079～0.170 mg·kg-1，其中2.0 mg·kg-1 Cd条件下番茄果实Cd质量分数全部超标．（2）不同质量分数Cd处理对29种番茄品种果实、地上部和地下部分生物量没有显著影响．（3）根据可食部位Cd质量分数、Cd转运系数、番茄植株生物量指标评价表明台湾黄圣女、黄金一点红、台湾珍珠、新402、元明黄娇子、台湾红圣女等6个品种可作为番茄的Cd-PSCs．

Potexperimentswereconductedtostudythedifferencesincadmium(Cd)absorptionand accumulation of 29 tomato varieties in the soils added with different concentration of Cd.Results show that:(1 )Cd concentrations are significant different (P<0.01 )in fruit among 29 tomato cultivars under two treatments (1.2,2.0 mg·kg-1 ),which ranging from 0.037 to 0.1 34,0.079 to 0.1 70 mg·kg-1 , respectively.In the 2.0 mg·kg-1 treatment,there is no variety which Cd concentration of fruit below the standard,so Cd-PSC is not exist in this treatment.(2)Root,shoot and fruit biomass of 29 tomato cultivars do not vary significantly under different Cd treatments (P>0.05 ),which indicate that tomato cultivars show tolerance to Cd toxicity to a certain extent4 (3 )Considering furthermore the concentration of Cd in the edible parts,transference coefficient of heavy metals,biomass of the tomato plants,cultivars Taiwanhuangshengnv,Huangjinyidianhong,Taiwanzhenzhu,Xin402,Yuanminghuangjiaozi and Taiwan-hongshengnv are considered as the potential tomato Cd-PSCs.
