Vase Life of Tinted Spikes of Tuberose Cultivar Suvasini

摘要

A study was undertaken to study the behavior of tinted spikes of tuberose cultivar Suvasini harvested at different stages. The experiment comprised two factors of which the first one was spikes treated with eight food dyes with 5% concentration for two hours and the second one was various stages of harvest. In Tuberose cv Suvasini, spikes harvested at stage 2(1-2 basal florets open) had a higher vase life of 8.01 days, highest mean water uptake of 59.42 g. spike1, lowest mean transpirational loss of48.55 g.spike"', highest mean diameter of florets of 3.65 cm, least decrease of 14.97 g/IOOg mean percentage of lipids and least decrease of 15.18 g/IOOg mean percentage of proteins. Concluding that for longer vase life of tinted spikes of tuberose cultivar Suvasini, the spikes are to be harvested and tinted at stage 2 with 1-2 basal florets open.
