| Abstract:
Cymbidium, the only cut flower among the orchids, occupies a proud position in global cut flower trade. The North-East Indian hills are the richest phyto-geographical habitat for this genus in India because of the prevailing supporting climate. These plants grow satisfactorily under mild climate. The present experiment was conducted on seven Cymbidium spp. and six acclaimed and popular hybrids at Kalimpong hills of Darjeeling range (between 20°31’ and 27°31’ North latitude & 87°59’ and 88°53’ East longitude. The hybrids were normally longer than spp. under evaluation and Cymbidium Tahiti was found as the tallest plant (16.66 cm) followed by C. Luana Imperial (15.66 cm) among the hybrids and C. giganteum (17.16 cm) was the tallest among the spp. followed by C. tracyanum (11.33 cm) and C. eburneum (10 cm). The maximum length of leaves was recorded in C. Goldengirl (124.53 cm) followed by C. Kennywine (121.43 cm) and C. Tahiti (119.8 cm) among the hybrids where as C. tracyanum (98.40 cm) and C. giganteum (97.83 cm) were promising among the spp. C. Luana Imperial was proved to produce maximum no. of shoots (20.0). C. Coronation had the largest flower in size (12.96 cm in length 12.13 cm in width) followed by C. tracyanum (9.03 cm 10.06 cm). The maximum no. of flowers per spike was found in C. lowianum (28.33) followed by C. elegans (27.33). C. lowianum also gave maximum no. of spikes per plant (2.66) followed by C. elegans (2.33). The longest spikes were produced by C. Polsti (140 cm) followed by C. Tahiti (127.66 cm). The flowers lasted long in C. Goldengirl (104 days) followed by C. Coronation (101 days) compared to other spp. and hybrids. | |
