Growth and Flowering Behaviour of Dendrobium Cultivars

Abstract

An experiment was conducted to evaluate growth and flowering behavior of three dendrobium cultivars coded from V 1 to V 3 (Sonia-17, Purple Boutonniere and Emma White respectively). Longest pseudobulb (78.9 cm) and maximum girth of pseudobulb (19.7 mm) was found with Sionia-17 cultivar. For the same cultivar, maximum other growth and flowering characteristics were observed and recorded as number of pseudobulb/plant (18.8), number of leaves/pseudobulb (5.3), leaf area (253.3 cm 2), number of spikes/plant (14.9), spike length (44.6 cm), spike girth (7.4 mm), number of florets/spike (12.2), diameter of bud (26.1 mm) and diameter of floret (9.5 cm). Minimum chlorophyll content (58.8%) was also found from cultivar Sonia-17 (V 1).
