Abstract
Orchid’s beauty mesmerizes to human being and creates a billion-dollar market worldwide. The aim of this study was to establish the cost-effective growth method for large scale production of commercially important white orchid plants. The growth and development of orchids was established through micropropagation and acclimatized for healthy growth in hydroponic system. Under this study the shooting of orchids was obtained on reported media and rooting of orchids was optimized. Different concentrations of NAA showed the highest number of roots (12) at 0.6mg/l whereas highest lengths of roots (1.8cm) were observed at 0.8mg/l. In this study hydroponics system was established for the acclimatization of orchid plantlets, for this purpose three different types of nutrient solutions were tested. Among three nutrient solutions, NPK (Nitrogen, Phosphorous, Potassium) was best nutrient solution for the effective growth and development of commercially important orchid plants. Therefore, this protocol is found to be most effective for the micropropagation of commercially important orchids.
