Effect of various chemicals as vase solutions on post harvest flower quality parameters in tuberose (Polianthes tuberosa) cut spikes

Present experiment was undertaken to study the effect of various chemicals as holding? solutions on few qualitative and quantitative parameters of tuberose cv. Prajwal. Out of ten treatments (including control), viz., 400 ppm 8-HQ, 100 ppm GA, 100 ppm TDZ, 50 ppm α-Lipoic acid, 25 ppm calcium chloride, 100 ppm benzoic acid, 50 ppm spermine, 50 ppm spermidine, 100 ppm benzyladenine, all in combination with 4% sucrose S and 250 ppm citric acid (CA) and control (RO water), 100 ppm benzoic acid + 4% S + 250 ppm CA, 50 ppm α-Lipoic acid+ 4% S + 250 ppm CA and 400 ppm 8-HQ + 4% S + 250 ppm CA were evaluated as the three best treatments for prolonging the vase life and improving qualitative parameters like overall flower quality and quantitative parameters, viz., percent change in fresh weight, maximum number of florets per spike at one time and diameter of florets in tuberose cv. Prajwal.
