| 摘 要： | 以赖氨酸及其类似物处理甘薯萌动种子。筛选对赖氨酸及其类似物反应不敏感、能过量积累赖氨酸的个体.探讨了赖氨酸及其类似物对鲜薯蛋白质含量、总氨基酸含量和赖氨酸的改良效果,并初步研究了R_1,R_2和R_3的遗传表现.研究认为,赖氨酸及其类似物处理甘薯萌动种子可明显地提高后代鲜薯的总氨基酸和赖氨酸含量,且可通过无性繁殖加以固定.

| Abstract: | The germinating seeds of sweet potato (Ipomoea batatas) were treated with lysine and its analogus in order to select the line tolerant to lysine and its analogus and overaccumulating amino acids. The effect of lysine and its analogus on the levels of protein, total amino acid and lysine in fresh root tubers as well as genetic performance of R_1, R_2 and R_3 lines was studied. The results showed that the levels of total amino acid and lysine were increased significantly by the treatments with lysine and its amalogus and the excellent traits can be fixed by clonal propogation. |
