In the present study, an effort has been made on pre-harvest physiology of Cymbidium orchid hyb. ‘Pine Clash Moon Venus’ as effected by pre-harvest foliar treatments and post-harvest physiology as effected by bud opening chemicals. Pre-harvest foliar application with GA3 (50 ppm) + BA (200 ppm) increased length of spikes, rachis length, number of florets per spike and flower longevity on plants in orchids. Longest spike (60 cm), rachis (30cm), highest number of spikes /plant (4) and number of florets per spike (15) were found with GA3 (50 ppm) + BA (200 ppm). Carbohydrate content in leaf was estimated maximum with BA (200 ppm) (182mg/g) followed by GA3 (50 ppm) + BA (200 ppm) (170mg/g). Highest per cent of fully opened buds (75%) and maximum vase life (45 days) were recorded with the chemical combination of Sugar 4% + Salicylic acid 200 ppm. Highest content of carbohydrate (140mg/g) was estimated at bud stage in fresh condition. Minimum carbohydrate content (60mg/g) was observed with Sugar 4% + 8-HQS (200 ppm) followed by Sugar 4% + Salicylic acid 200 ppm) (64mg/g).
