SUBSTITUTION OF SYNTHETIC HORMONES WITH ORGANIC MATERIALS ON THE GROWTH OF ORCHID PLANTS (Phalaenopsis amabilis) AS A GROWTH REGULATORY SUBSTANCE IN VITRO

In Indonesia, the agribusiness sector has begun to expand due increase in entrepreneurship of orchid plants. Several genera and species plants are promising be traded as ornamental plants, one which is moon (Phalaenopsis amabilis). However, limited number seeds or produced by conventional propagation methods takes a long time get new tillers. Therefore, tissue culture techniques can used grow reproduce success vitro culture, balance growth regulators an essential factor. On other hand, synthetic hormones such 1-naphthalenaecetic acid (NAA) 6-benzylaminopurine (BAP) relatively expensive. The study this research substitute NAA BAP with organic ingredients that cheap easy find. Such Purple Sweet Potatoes Beans find out right concentration matter. This completely randomized design two factorials (concentration purple sweet potato green beans) three repetitions. PLB (Protocorm Like Bodies) amabilis) was treated with: positive control (2 ppm), negative (without addition hormones), variations beans result C4D0 (500g/L extract 0 g/L bean extract) excellent formulation, although there no significant interaction between extracts against orchid.
