Rapid propagation method for draceana arborea tissue culture

Abstract

The invention discloses a rapid propagation method for draceana arborea tissue culture, which takes steams and lateral buds of draceana arborea as explants for tissue culture. A great amount of draceana arborea maintaining excellent female parent properties is obtained by explant pretreatment and disinfection, explant budding induction, rapid propagation, cluster bud strong seedling culture, rooting culture and acclimatization and transplant. The method has the benefits that explant budding induction success rate and transplanting survival rate are increased by adding Tween to an explant disinfectant, rooting percentage of rooting culture is increased by strong seedling culture, and a great amount of the market requirement for draceana arborea is met.

Description

technical field [0001] The invention belongs to the technical field of plant tissue culture, and in particular relates to a rapid propagation method of golden heart Yemen iron tissue culture. Background technique [0002] Dracaena, also known as: Bleeding Tree, Holy Medicine for Invigorating Blood, Plant Longevity. It is mainly distributed in Cambodia, Laos, Vietnam and other places in Southeast Asia; in China, it is mainly distributed in tropical and subtropical limestone mountains at an altitude of 250-1700m in southern Yunnan and southern Guangxi. Dracaena likes high temperature and humidity, likes light, is not cold-resistant, and if the temperature is too low, yellow-brown spots will appear on the tip and edge of the leaf due to insufficient water absorption by the root system. The shape of the tree is beautiful and regular, and the shape and color of the leaves are colorful. It has high ornamental value and is an excellent foliage plant for modern interior decoration....
