摘要:重楼为我国名贵中药材,极具药用价值。近年来重楼药材需求量逐渐增加,人工栽培存在瓶颈,野生资源开采陷入恶性循环,且已严重透支。因此,在加强重楼资源保护的同时,积极深入开展基础研究,破解种苗繁育问题,推动人工栽培,以满足市场需求,对实现重楼资源的可持续发展和采用具有重要意义。本文综述了重楼种苗繁育现状,包括种子繁殖、茎段繁殖及组织培养等,为重楼规范化种植、资源保护与利用提供参考。

Abstract: Paridis Rhizoma is a rare Chinese herbal medicine with variety of medicinal values. In recent years, the demand for Paridis Rhizoma has increased gradually. Artificial cultivation has met difficulties, while exploitation of wild resources was caught in a vicious circle and has overdrawn seriously. So it is of great significance to enhance the protection of Paridis Rhizoma, carry out basic research, in order to solve problems in seeding breeding, promote artificial cultivation to meet the market need and achieve sustainable development and supply. This article reviewed the status qua of seedling breeding of Paridis Rhizoma, including seed breeding, tuber breeding and tissue culture, with a purpose to standardize planting of resource conservation and utilization of Paridis Rhizoma.
Key words: Paridis Rhizoma; seeding breeding; tissue culture; review
中药材重楼为百合科重楼属植物云南重楼Paris polyphylla Smith var. yunnanensis(Franch.)Hand. -Mazz.或七叶一枝花Paris polyphylla Smith var. chinensis (Franch.)Hara的干燥根[1]。《神农本草经》与《本草纲目》对其药用情况具有较详细的记载,是云南白药系列、宫血宁胶囊等产品的主要原料。近年来对重楼资源需求逐年增加,但忽视了对重楼资源的保护和繁育,乱采滥挖现象凸显,重楼野生资源已陷入开采的恶性循环,导致野生资源严重透支。因此,人工种养亟待升级,其中,种苗繁育是野生资源人工栽培研究、中药材规范化种植及整个中药产业发展的源头。但目前重楼种苗繁育研究出现瓶颈,如何有效、快捷解决“源头之困”已成为当务之急。兹就近年来重楼
种苗繁育技术方面的研究进行系统综述,以期为中药材重楼种苗繁育及人工栽培提供参考。
1 种子繁殖
1.1 种子休眠机理研究
重楼的种子产量较大,通过种子的有性繁殖是获得大量种苗的有效方法。……
