 ABSTRACT

An investigation was carried out at orchidorium, Regional Horticultural Research and Extension Centre, University of Horticultural Sciences campus, GKVK, Bengaluru during October 2015 to June 2017 to study the comparative performance of eight varieties of dendrobium orchid Viz. Ear Sakul, Mono Red, Charming White, Bubble Gum, Sonia-17, Burana Jade, Big White and Nopporn Pink under naturally ven tilated polyhouse and 50 per shade house condition. Plants grown under polyhouse condition exhibited maximum plant height, number of shoots per plant, number of pseudobulbs per plant, number of leaves per plant, leaf area and chlorophyll content in leaves (20.06 cm, 3.39, 3.57, 8.23, 38.52 cm2 and 47.64 spad units respectively) during crop growth period and it was minimum (17.66 cm, 2.68, 2.87, 7.04, 34.83 cm2 and 44.85 spad units respectively) under shade house condition at 18 months after planting. With respect to varieties, maximum plant height (32.21 cm) was observed in var. Mono Red and minimum in var. Burana Jade (18.87 cm), number of shoots per plant and number of pseudobulbs per plant was highest in var. Big White (3.80 and 4.50     respectively). Number of leaves per plant was found maximum in var. Big White (9.75) and minimum in var. Charming White (6.33). Largest leaf area was noticed in var. Mono Red (44.45 cm2) and smallest was found in var. Charming White (30.42 cm2). Chlorophyll content in leaves was found highest in var. Sonia-17 (57.08 spad units) and lowest in var. Charming White (38.66 spad units) The number of spikes per plant and per meter square was found highest in var. Big White (1.77 and 61.83 respectively) and it was minimum in var Burana Jade and Nopporn Pink ( 1.17  and 40.83  respectively).
Relatively vase life was highest in var. Mono Red and Big White (40.00 days) and lowest was observed in var. Nopporn Pink (20.83 days).

Key words: Dendrobium, Varieties, Polyhouse, Shade house, Spikes.
