摘要: 西印度醋栗(Phyllanthus acidus (L.) Skeels)是一种生长于热带地区的乔木, 兼具食用和药用价值, 开展其组培快繁技术探究, 可促进其资源的持续开发和利用。本研究以西印度醋栗茎尖为外植体材料, 对初代培养、继代增殖培养及生根培养的方案进行了初步筛选。结果表明, 初代培养最适培养基为MS+2.0 mg·L–1 6-BA+0.2 mg·L–1 NAA, 外植体诱导萌发率达81.11%; 继代增殖最适培养基为MS+1.0 mg·L–1 6-BA+0.2 mg·L–1 IBA, 增殖系数达1.86; 生根最适培养基为MS+1.5 mg·L–1 IBA, 生根率达83.00%; 炼苗7天后移栽, 移栽基质为珍珠岩、泥炭土、腐殖质=1:1:1 (v/v/v), 成活率为90%。从接种外植体到获得再生植株约90天时间, 为西印度醋栗的资源保护与产业化应用提供了技术支持。

Abstract: Phyllanthus acidus (L.) Skeels is a tropical tree with both edible and medicinal properties. Exploring its tissue culture and rapid propagation technology can promote the sustainable development and utilization of its resources. In this study, the stem tips of P. acidus were used as explants, and the schemes of primary culture, secondary proliferation culture and rooting culture were screened. The results showed that the optimal medium for primary culture was MS+2.0 mg·L–1 6-BA+0.2 mg·L–1 NAA, and the induced germination rate of explants reached 81.11%. The optimal medium for subculture was MS+1.0 mg·L–1 6-BA+0.2 mg·L–1 IBA, and the proliferation coefficient was 1.86. The optimal medium for rooting was MS+1.5 mg·L–1 IBA, and the rooting rate reached 83.00%. After 7 days of cultivation, the seedlings were transplanted with perlite, peat soil and humus=1:1:1 (v/v/v), and the survival rate was 90%. This study took about 90 days from inoculation of explants to obtaining regenerated plants, providing technical support for the resource conservation and industrial application of P. acious.
