Abstract: Storage of cut flowers is an important postharvest horticultural technique to regulate market and low temperature storage is the most common commercial method used for cut flowers. ‘The maintenance of flower quality during storage and length of time that flowers can be stored depends on several factors such as genetic characteristics, respiration rate, water loss, ethylene production and action, bacterial and fungal development. Storage of cut flowers mainly depends on the stage of harvest. Therefore, this investigation was carried out to determine the optimum stage of harvest for better storage life and quality. An experiment was conducted to study the effect of stage of harvest and bud opening solution on the postharvest quality and vase life of carnation cut flower cvs. Pink Donna and Design. Four harvest stages viz., tight bud, cross bud, paint brush and fully open stages of the two cultivars were pretreated in bud opening solution containing 10 per cent sucrose + 200 ppm 8-Hydroxy Quinoline Sulfate (HQS) + 25 ppm Aluminium sulfate. Tight bud stage flowers pretreated in bud opening solution showed maximum vase life of 12 days in cv. Pink Donna, 11.3 days in cv. Design. It was also observed that pretreatment in the bud opening solution resulted in increase of flower diameter, higher water uptake and reduced number of days taken for bud opening. Rate of respiration and ethylene production were found to be least in tight bud stage flowers.
