白菜镉积累基因型差异研究

Investigation of Genotypic Difference of Cadmium Contents in Shoots of Brassica campestris ssp.chinensis

采用 8 7个白菜品种 ,于春夏和秋冬两生长季节在镉 (Cd)污染土壤中进行植株地上部Cd积累差异研究。结果表明 ,不同品种间镉含量存在极显著差异 。

Cadmium contents in the shoots of 87 cultivars of pakchoi(Brassica campestris ssp.chinensis L.)were studied in a Cd-contaminated soil in two growth seasons.Significant differences of shoot Cd contents were found among the cultivars.Cd contents in spring and summer were higher than in autumn and winter.
