Abstract
Investigations were carried out to study the effect of precooling and preservative chemicals on post harvest longevity of the florets of tuberose (Polianthes tuberosa L.) cv. Prajwal. The effect of precooling of tuberose florets in combination with four chemical treatments were studied and observations were recorded based on quality parameters like freshness of the florets, colour retention, physiological loss in weight and days to fifty per cent wilting. Pre-cooling of flower buds was found to improve the longevity (shelf life) of flower buds. Soaking of florets in 4% Boric acid solution for two hours and air drying them before packing increased the shelf life up to six days.
