摘要: 研究几种外源激素IAA、GA和BAP互作对马铃薯试管薯形成和发育的影响,结果表明,IAA与GA互作对马铃薯试管苗生长有积极的促进作用,能够明显提高试管苗的高度,最大增幅可达90.3%,而IAA与BAP互作对试管苗生长有明显抑制作用。IAA与GA互作对试管苗根的形成和生长影响不明显。BAP对试管薯形成有重要作用,而GA与BAP互作能进一步促进试管薯生长,处理4(IAA+GA+BAP)比处理3(IAA+BAP)的试管薯鲜重和直径分别增加163.8%和46.4%。

Abstract: The interaction effects of IAA, GA and BAP on the formation and development of potato microtuber in vitro was studied.The results showed that the interaction between IAA and GA could accelerate the growth of potato microtuber, the highest increment was 90.3%, but the interaction between IAA and BAP could restrain the growth; the interaction between IAA and GA had no significant effect on the formation and growth of plantlet root.BAP was a very important factor for potato formation, and the interaction between GA and BAP could accelerate the potato growth.The fresh weight and diameter of potato plantlets in Treatment 4 increased 163.8% and 46.4%respectively than those in Treatment 3.
