The invention discloses a rapid propagation method for the tissue culture of rhubarb, the perennial herb of the genus rhubarb, the fleshy root and the rhizome of the rhizome. The stems are hollow green, smooth and glabrous, with longitudinal lines. Single leaves alternate, basal leaves round or oval, with sharp spaped teeth on the edges and white short spines on leaves; small stems. Autumn light yellow flowers, large conical inflorescence top; achenes oval oval, 3 edges, along the edge of wings, wing edge translucent. Root and rhizomes were used as medicine. Autumn and winter harvest, to rough skin, dry spare slice. In wet places. The flavour of rhubarb is bitter, and the sex is cold. It has the effect of diarrhea and blood stasis and blood stasis. The invention takes rhubarb seeds as explants, the callus induction, proliferation, differentiation, rooting and transplanting process was successfully isolated and cultured plants of rhubarb, rhubarb tissue rapid propagation technology system establishment, in order to save the amount of cultivation, improve the yield of medicinal materials, provide a way of rapid propagation the proliferation of.

一种大黄组培快繁方法
本专利技术属于农业植物培育领域,具体涉及一种大黄组培快繁方法。
技术介绍
大黄又名:将军、川军、生军、马蹄黄、锦纹。属多年生草本,高达2米。肉质根及根状茎粗壮。茎中空绿色,平滑无毛,有纵纹。单叶互生;具粗壮长柄,柄上生白色短刺毛;基生叶圆形或卵圆形,长宽均达35厘米,掌状5~7深裂,裂片矩圆形,边缘有尖裂齿,叶面生白色短刺毛;茎生叶较小。秋季开淡黄色花,大圆锥花序顶生;花被6裂,雄蕊9个。瘦果矩卵圆形,有3棱,沿棱生翅,翅边缘半透明。根及根状茎入药。秋末冬初采收,去粗皮,切片干燥备用。生长分布于西北、西南各省,南方高寒山区有栽培。多生于阴湿处。大黄味苦,性寒。具有泻实热,破积滞,行瘀血。本专利技术以大黄种子为外植体,通过愈伤组织诱导、增殖、分化、生根、炼苗移栽等过程成功获得大黄离体再植株,建立大黄组织培养快速繁殖技术体系,为节约栽培生产中的用种量,提高其药材的产量及为大黄进一步开展遗传转化研究奠定基础。
