Effect of Pulsing Solutions and Stages of Spike Harvest for Refrigerated Storage on Postharvest Quality of Gladiolus Cut Spikes

An experiment was conducted to find out the effect of pulsing solutions and stages of spike harvest for refrigerated storage on postharvest life of gladiolus cv. White Prosperity cut spikes. Among all the pulsing treatments i.e., T, -Sucrose 20% + STS 200ppm, T2-Sucrose 20% + STS 200ppm + GA3100 ppm, T3-Sucrose 20% + STS 200ppm + GA3200ppm/ T4-Sucrose 20% + STS 300ppm + GA3 300 ppm, T5-Sucrose 20% + STS 200ppm+GA3400ppm and T6-control (with distilled water), treating of cut spikes with Sucrose 20% + STS 200ppm + GA3300ppm was found superior to other treatments. However, appropriate stages of spike harvest for.wet refrigerated storage was found superior on the characters like maximum days to opening of basel floret, floret size, floret longevity, vase life, number of florets open at time, per cent opening of florets, percentage of florets open at a time and water absorption per spike, were recorded in Do storage duration (no storage), while maximum days to opening of basel florets and vase life were recorded in S1 stage (tight bud stage). The maximum floret size and floret longevity were recorded in S2 stage (tight bud stage). The maximum number of florets open at a time, per cent opening of florets at time and maximum water absorption per spike were recorded in S3 stage (when basal floret was half open).
