Abstract

A study was carried out to explore the effect of length of stem and stage of harvest on vase life and display quality of tuberose. As regards stem length, 90 cm stem length (L₄) had longest vase life, maximum uptake of water, minimum loss-uptake ratio, maximum fresh weight and percentage of opened florets, and, lowest percentage of abscised floret; whereas, 60 cm stem length (L₂) enhanced longevity of individual florets. In the case of stage of harvest, significantly high vase life, least loss of water, minimum loss-uptake ratio and lowest physiological loss of weight were recorded in two-florets open stage (S₃). Maximum percentage of opened florets and lowest percentage of abscised florets were observed in three-florets open stage (S₄), whereas, maximum uptake of water and fresh weight of spike were seen in one-floret open stage (S₂). Interaction effect of stem length and harvest stage was also found to be significant showing that 75 cm of stem length with one-floret open stage (L₃S₂) was superior for maximum vase life of spike as well as lowest physiological loss of weight.

Abstract

Studies conducted to find out the effect of date of harvesting and floral preservatives on vase life and quality of tuberose cv. Double revealed that among treatments, harvesting on 1^st October (D₈) was better for longer vase life, whereas, 15^th August (D₅) for minimum loss of water, maximum fresh weight of the spike and percentage of opened florets. Similarly, harvesting on 15^th September (D₇) was found better for longest floret longevity as well as loss uptake ratio. In case of floral preservatives, the treatment 500 ppm aluminum sulphate + 4% sucrose (C₆) was found better for longer vase life, maximum uptake of water, lowest loss-uptake ratio and maximum fresh weight of spike, whereas, 400 ppm 8-HQS + 4% sucrose (C₈) for maximum floret longevity and floret circumference as well as maximum percentage of opened and lowest percentage of neck bent florets. The treatment, 50 ppm silver nitrate + 4% sucrose (C₃) exhibited lowest loss of water. In case of interaction effect, 1^st October with 500 ppm aluminum sulphate + 4% sucrose (D₈C₆) was found superior for maximum vase life of spike, highest uptake of water and fresh weight of spike.
