ABSTRACT
The present 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 ventilated polyhouse and 50 per shade house condition. Plants grown under polyhouse condition took early days to bud initiation (291.55 days), days to first floret opening (33.17 days) as compare to shade house condition. The floral characters like spike length (30.90 cm), rachis length (17.59 cm), number of florets per spike (5.83) and floret diameter (7.04 cm) was found highest under polyhouse condition. Spike yield per plant and per meter square (1.48 and 51.63 respectively) was observed highest under polyhouse and least was noticed in shade house condition. With respect to varieties, early initiation of bud and spike emergence to first floret opening was (214.37 days and 30.42 days respectively) was recorded in var. Big White. The floral qualities like spike length (37.54 cm) and rachis length (23.06 cm) was recorded in highest in var. Mono Red. Number of florets per spike (7.55) was maximum in var. Bubble Gum and minimum in (3.70) was observed in var. Nopporn Pink. Floret diameter (8.40 cm) was found highest in var. Sonia-17. Spike girth (4.10 mm) and spike weight (22.98 g) was found superior in var. Mono Red. 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)
