石斛兰花型繁多、花色艳丽,既可作为切花观赏,又可作为盆花栽种,与卡特兰、蝴蝶兰和万代兰合称“四大洋兰”。石斛兰已是一种重要的年宵花卉,广受市场欢迎。鉴于石斛兰的大量需求,传统的繁殖方法严重制约了石斛兰的繁殖,无论是数量的扩大,还是植株的株型、花色等的改良,传统的繁殖方法都无法逾越这个瓶颈。而采用植物组织培养技术能大量扩繁石斛兰的数量,并且采用脱毒技术能获取无病毒植株,对植株的性状改良起决定性作用。基于此, Dendrobium Orchid variety, beautiful colors, both as cut flowers ornamental, but also as a potted plant, and Cattleya, Phalaenopsis and Bandai collectively known as the “four ocean blue.” Dendrobium is an important annual flower, widely welcomed by the market. In view of the huge demand of Dendrobium, the traditional method of reproduction severely restricts the reproduction of Dendrobium or Dendrobium orchid. Whether it is the expansion of numbers or the improvement of plant type and flower color, the traditional breeding methods can not overcome this bottleneck. The use of plant tissue culture technology can greatly expand the number of Dendrobium, and use of virus-free technology to obtain virus-free plants play a decisive role in plant improvement.
