Abstract:
Dragon fruit (Hylocereus undatus) belongs to the family Cactaceae and are climbing vines that have received worldwide attention recently. The seed viability of stored dragon fruit is very low, stem cuttings are used as planting material in dragon fruit but the plant dose not exhibit a sufficient number of buds to regenerate plants on a large scale. Therefore, in vitro propagation techniques can meet the high demand of plants throughout the year. When the successfully in vitro raised plantlets of Dragon fruit are transplanted from the culture room to greenhouse conditions, they may desiccate or wilt rapidly and can die because of changes in the environment, unless substantial precautions are taken to adapt plantlets to a new environment. To improve the survival percentage under hardening Soil, sand, vermi compost and cocopeat in (1:1:1:1) combination was proved to be the best for maximum success in ex vitro survival of dragon fruit plantlets.
