Effect of pre and post treatments and storage durations on vase life of polypropylene packed cut rose var. passion

A study was conducted to find out the effect of pre and post storage treatments on polypropylene sealed packed cut roses with different cold storage (2o) durations viz., 5, 10, 15, 20, 25 and 30 days. PP packed flowers treated with pre and post storage vase solution consisting of 5% sucrose + 8 HQC 300 mg/l + α-lipoic acid 200 mg/l, cold stored up to 20 days showed promising results with maintained flower quality. In general the trend showed decrease in water uptake, foliage intactness and vase life as well as higher bent neck with increase in storage duration. However, the treatment of pre and post storage showed maintained foliage intactness, higher water uptake, low bent neck with vase life of 6.69 days in cut roses stored up to 20 days. Whereas the flowers stored up to 15 days without any pre and post storage treatment with PP sealed packing maintained quality with vase life of 5.62 days.
