| 摘 要： | 以室内苗期低钾介质中筛选出的10个耐低钾变异后代和其对应的5个接受外源DNA导入的水稻亲本为材料，比较研究在正常钾和低钾两个水平下的根系生理，发现在低钾条件下耐低钾后代的根长、根干重均比其受体要大，根系活力比其受体要强，表现出受缺钾影响较小的特性。

| Abstract: | Ten K deficiency tolerant rice materials and five recipients are cultured in nutrition solution Under low potassium supply,root length and dry weight of the K-deficient tolerant rice are longer and higher than their recipients The K-deficit tolerant rice root system activity has been greater than that of their recipients |
