Abstract: The present study was conducted during 2013-14 to prolong the post-harvest life of tuberose using single or combined holding solutions. Tweleve holding solutions, viz. T1: 300ppm Al2SO4 T2: 100ppm CoCl2 T3: 5%Sucrose + 300ppm Al2SO4, T4: 5%Sucrose + 250ppm Citric Acid T5: 5%Sucrose + 25 ppm KMnO4, T6: 5%Sucrose +100ppm CoCl2 T7: 200ppm Citric Acid T8: 5%Sucrose +200ppm Citric Acid, T9: 5%Sucrose + Calcium hypochlorite(Ca(ClO)2), T10: 5%Sucrose + 200ppm 8HQC, T11: 5%Sucrose + 200ppm 8HQC + GA3 100ppm and T12: Control (Deionized water) were used in a completely randomized block design with 3 replications. The results showed that holding solutions in single or in combined form significantly affected the post harvest quality of tuberose. The maximum vase life, floret size, vase life of individual flower, floret opening percentage and solution absorption by spikes were obtained with T4 (5%Sucrose + 250ppm Citric Acid) while maximum days to opening of basal florets and number of florets open at senescence of basal floret were obtained when spikes were held in containing the solutions (5%Sucrose + 300ppm Al2SO4) under the treatment T3.
