杜鹃属是杜鹃花中最大的属,是我国植物区中的大属之一。杜鹃属的植物在植物学中占有比较重要的地位,自从杜鹃属植物被发现后,经过各种方式的栽培,在世界范围内已经形成了600多种杜鹃花。映山红亚组是杜鹃花组培养的主要模式,这种组织培养技术已经比较成熟,但是,对于常绿杜鹃的组织培养技术却不是特别成熟。杜鹃花的花期比较长,人们常用播种、扦插和嫁接的方式促进杜鹃花的繁殖。但是,这些繁殖方式会受到季节因素和母株特征的制约,而且,杜鹃花的花期长,不能适应商业化规模的生产,在市场上经常出现供不应求的现象。
Rhododendron is the largest genus azaleas, is one of the genus in our plant area. Rhododendron plants in the botany occupy a more important position since the rhododendron was discovered, after a variety of ways of cultivation, the world has formed more than 600 kinds of azaleas. Azalea group is the main mode of rhododendron culture, this tissue culture technology has been relatively mature, but for the evergreen cuckoo tissue culture technology is not particularly mature. Rhododendron flowers relatively long, people often use sowing, cutting and grafting way to promote rhododendron reproduction. However, these breeding methods are constrained by seasonal factors and mother plant characteristics. Moreover, the long flowering season of rhododendron can not be adapted to the production on a commercial scale, and the supply often falls short of demand in the market.
