摘要
以叶片为外植体,探讨红叶石楠红唇愈伤组织诱导及植株再生的方法。结果表明,无菌繁殖体系以MS+BA0.3mg/L+NAA1.5mg/L为佳;丛生芽的增殖以MS+BA2.0mg/L+IBA0.1mg/L+GA33.0mg/L+糖30g最适;生根培养用1/2MS+IBA0.3mg/L较好。经生根的试管苗移栽于草炭:蛭石:珍珠岩:2:2:1的混合基质中,温度22~28%,相对湿度90%-100%,保湿7~10d,其间适当遮荫,25d的成活率超过95%。
The leaves of Photinafrasery cv. Red Tip were used as explants in tissue culture to induct callus and plantlet regeneration. The study results showed that the optimum medium was MS + 0.3 mg BA/L + 1.5 mg NAA/L for the callus induction;the optimum medium was MS + 2.0 BA mg/L,0.1 mg IBA/L + 3.0 mg GA3/L + 30g sugar/L for proliferation of the sub-cultured buds; the optimum medium was 1/2 MS + 0.3 mg IBA/L for rooting. The survival rates of the rooting planflets transplanted into the substrate containing 40% venniculate,40% pearlite, and 20% peat (v/v) was 95% after 25 days transplanting under the conditions of 22 - 28℃, 90%-100% of relative humidity, and keeping moisture for 7-10 d.
