Dahlia
This research has conducted for searching appropriate light intensity and growth regulator substance concentration to induce flowering on Paphiopedilum. The result showed that Paphiopedilum praestans (Rchb. F.) Pfitzer treated by light intensity 60 %, growmore and GA 0.5 mg · L-1 is the earliest flowering. The length of the flower stalks on Paphiopedilum praestans (Rchb. F.) Pfitzer treated by light intensity 60 %, growmore and GA dose 0.5 mg · L-1 is the longest stalks. The petals number of flowers per stalk on Paphiopedilum praestans (Rchb. F.) Pfitzer treated with light intensity 60 %, liquinox bloom and AIA 0.5 mg · L-1 is the largest number of flower petals and the earliest flower blooming. On the Orchid Paphiopedilum praestans (Rchb. F.) Pfitzer treated by light intensity 30 %, liquinox bloom and AIA 0.5 mg · L-1 is 105 d faster. An increasing number of the Paphiopedilum praestans (Rchb. F.) Pfitzer leaves treated with light intensity 60 %, growmore and GA doses 0.5 mg · L-1 is more plentiful than Paphiopedilum glaucophyllum J. J. Smith and Paphiopedilum mastersianum (Rchb. F.) Stein. © 2016 Author(s).
