1 液体浅层倒插生根法 将长约1.5～2.0cm长的巨尾桉继代苗,不必分头尾投入装在三角瓶深约3mm,添加2～10mg/L、IBA、液体的、修改的MS培养基内,只要苗的任一部分(茎顶、叶子或茎基部)接触到培养液,7～10天后可有80％以上生根。生根苗移栽成活率80％左右。这一方法较一般生根法降低成本3/4,并便于今后组培苗实现机械化、自动化生产。 1 liquid shallow incisal rooting method will be about 1.5 ~ 2.0cm long giant eucalyptus seedlings, do not have to sub-tail into the triangular flask about 3mm, add 2 ~ 10mg / L, IBA, liquid, modified MS medium, as long as any part of the seedlings (stems, leaves or stem base) contact with the culture medium, 7 to 10 days after more than 80% can be rooted. Rooting transplanting survival rate of about 80%. This method than the average root canal method to reduce costs 3/4, and facilitate future tissue culture seedlings to mechanization, automated production.
