Effect of Orchid Fertilizers and Multi-vitamins on Growth of Dendrobium findlayanum Par. & Rchb. f. In Vitro.

Abstract

Orchid fertilizes 1 g l-1 of formula 21-21-21, 30-20-10, 16-8-12+2 MgO, 18-18-18 and
chemicals from Vacin and Went (1949) or Murashige and Skoog (1962) medium were used in
culture media for seedlings of Dendrobium findlayanum Par. & Rchb. f. in Vitro. In one litre of each
medium containing 150 ml l-1 coconut water, 100 g l-1 blended banana, 20 g l-1 sugar , 8 g l-1 agar
and 2 g l-1 activated charcoal with or without muti-vitamins. After 3 months it was found that
medium for seedling growth and development was 16-8-12+2 MgO orchid fertilizers. When
transplanting the the seedlings into 1 inch pot without growing medium or with coconut dusts,
moss, charcoal for 4 a month. The seedling which grew in coconut dusts gave the highest sevival
rate of approximately 96.66%.
