摘　　要：研究了贵州省 7个主栽水稻品种在 0 .5 mol/L霍格兰营养液中的幼苗生长和钾离子含量。结果表明 :缺钾状况下 ,不同基因型水稻的幼苗生长和钾离子含量不同 ,其中汕优多系 1号的幼苗生长最好 ,吸钾能力最强 ,其耐低钾的能力也最强 ,其次是汕优 6The seedling growth and k + content of seven main varieties of rice in osmyl hongland nutrient sotution in guizhou was studied. The result indicated that in state of potassium dificiency, the seeding grouth state and k + content of each rice were different. Among them, the seeding growth of Shan You-1 was the best. The ability of absorbing potassium was the strongest. And the ability of bearing low potassium was also the strongest and Suan You-63 followed it.
