Abstract :  An experiment was conducted to find out the effect of pulsing solutions on postharvest life of gladiolus cv. Peater Pears cut spikes. Among all the pulsing treatments , treatment, T4 (20% Sugar + 200ppm STS + 200 ppm GA3) gave maximum vase life, floret size, minimum days to open basal floret, maximum floret longevity, floret opening percentage while treatment T7 (20% sucrose + 300 ppm Al2SO4 + 200 ppm GA3) attained maximum number of floret, floret weight and floret open at a time during the study.
