摘要
紫茎泽兰是世界头号入侵杂草,建立紫茎泽兰无性系,可以在短时间内提供大量遗传背景一致的植物材料,以研究它入侵的生理生化及分子生态学机制。利用丛生芽微繁技术培养紫茎泽兰的研究表明:M S+6-BA2.0mg/L+NAA 0.05mg/L+KT 3mg/L为丛生芽增殖的最适培养基;而1/2M S+IAA 0.1mg/L对生根最有利;试管苗经炼苗后移栽成活率达98%。
Eupatoriurn adenophorurn is the fastest inbreak weed in the world. Establishing Eupatorium adenophorurn clone can supply affluent plant materials with consistent genetic background in a short time to study the physiological and molecular ecological mechanism of incursion. The results showed that the optimal medium for the multiplication of cluster buds was MS＋6-BA 2.0mg/L ＋NAA 0.05mg/L＋KT 3mg/L, and the best medium for rooting was 1/2MS＋IAA 0. lmg/L. The survival rate of hardened plantlets was 98% after transplanting.
