Abstrak
Orchids have a very slow vegetative growth, thus requiring special treatment in the grown. To spur growth and development can be used through tissue culture techniques of multiplication. But the success of the technique of tissue culture is inseparable with give a substance on the plant growth regulator. This study aims to determine the growth an influence D. phalaenopsis Fitzg orchids of giving againts with IBA administration and Kinetin according to in vitro and as well as to obtain a concentration combination of IBA and Kinetin on the best orchid D. Phalaenopsis Fitzg explants. Based on the results of the study indicate that the combination of IBA and Kinetin concentration giving a influence percentage of live explants, number of shoots and number of roots orchid D. phalaenopsis Fitzg explants. Combination treatment of IBA 1.0 ppm and 0.1 ppm Kinetin is a combination of the best treatment to produce a number of shoots orchids. The giving of IBA 0.5 ppm in the medium without the addition of kinetin concentration can increase the number of roots of the orchid D. phalaenopsis Fitzg.
