摘要
通过不同施磷水平处理的盆栽试验，测定了１５ 个油菜品种的地上部、地下部干重和植株总磷含量，并对参试品种进行了耐低磷能力评价。试验结果表明：油菜耐低磷能力存在基因型的差异，通过研究低磷条件下植株生理变化来进行耐低磷油菜品种的筛选是可行的。
Rape varieties from three genotypes (B. compestris L. B. juncea L and B. napus L) were compared in two treatments with their adaption to low level of phosphorus. The results indicated a significant genotypic variation of low phosphorus tolerance among the tested varieties. Rape varieties of highly-genotype tolerant to P deficiency are recommended for breeding of high-yielding varieties with tolerance to P deficiency.
