摘要
本文以光叶楮为试验材料,研究了不同激素及其组合对外植体快速繁殖及诱导生根的影响,结果表明:MS+6-BA1.5mg/L+NAA0.5 mg/L为最佳增殖培养基,繁殖系数为3.4,平均芽高为4.0cm,且生长快、芽苗质量高;1/2MS+NAA0.3 mg/L为最佳生根培养基,生根率为72%,根系质量好;在移栽试验中发现,移栽基质以蛭石比珍珠岩更好,炼苗成活率达到88%。
Broussonetia papyrifera were regarded as test materials in this paper. This test studied the influence of different kinds and different concentration of hormone on the tissue culture rapid propagation of B. papyrifera. The results shows： MS ＋ 6-BA1. 5 mg/L ＋ NAA0.5 mg/L is the best optimum medium, the modulus of propagation arrived at 3.4, the average seeding height is 4.0cm, and the seedling grow fast, the bud shoot is high in quality; when the rooting index reached 72% in rooting medium of 1/2MS ＋ NAA 0.3 rag/L, the root system is of high quality; Plantlets from test tube grew better on the growth medium vermiculite than on perlite in acclimatization stage, the survival rate reached 88%.
