摘要
以棉花竹(Fargesia fungosa)成熟种胚诱导出的芽作为材料,研究其快速繁殖技术。结果表明:棉花竹的最佳增殖培养基为MS(Murashige and Skoog)+3 mg/L BA(6-苄基腺嘌呤),增殖系数为3.77,芽丛生长旺盛;最佳生根培养基为1/2MS+3 mg/L IBA(吲哚丁酸),生根率达100%,根系较长且粗壮;试管苗移栽至泥炭、蛭石、珍珠岩配制比例为1∶1∶1的混合基质中,成活率高达98%。本研究结果为棉花竹的扩繁和产业化生产提供了技术支撑,对箭竹属其他竹种的组织培养具有重要的参考价值。
The buds induced from mature embryos were used as explants to study the rapid propagation technique for Fargesia fungosa. Murashige and Skoog＇ s （MS） medium supplemented with 3 mg/L BA was the optimal medium for bud multiplication. The highest proliferation coefficient was 3.77, and the cluster buds grown well. The suitable rooting medium was 1/2 MS supplemented with 3 mg/L IBA. The rooting rate was up to 100% , and the roots were long and thick. The survival rate of hardening plantlets was 98% after being transferred to a mixture of peat, vermiculite and perlite with a ratio at 1 ： 1 ： 1. The study provides technical support for the propagation and industrialization production of Fargesia fungosa, and also is of important refer- ence value to the tissue culture of other species in the genus.
