Abstract
The present investigation entitled "Effect of floral preservatives and growth regulators on post harvest quality and vase life of tuberoseā was carried out at laboratory of Department of Horticulture, CCS Haryana Agricultural University, Hisar during the year of 2022. Fifteen treatment combinations consisting of seven chemicals viz., sucrose (2% and 4%), citric acid (250 mg/l and 350 mg/l), silver nitrate (25 mg/l and 50 mg/l), aluminium sulfate (150 mg/l and 300 mg/l), gibberellic acid (100 mg/l and 150 mg/l), benzyal adenine (100 mg/l and 150 mg/l) and salicylic acid (100 mg/l and 150 mg/l) along with control (distilled water) were used in Completely Randomized Design with three replications. The vase solution of 4% sucrose + 150 mg/l salicylic acid (SA) was found promising in terms of number of opened florets per spike, percentage of opened florets per spike, freshness index, spike weight at wilting of 3rd floret, floret diameter, vase life and water uptake. This treatment was also found significant in reducing number of unopened florets per spike, water loss/water uptake ratio, physiological loss in weight and proximal end browning. However, the minimum days to opening of 3rd floret and number of florets open at a time was recorded in 4% sucrose +300 mg/l aluminium sulfate treatment.
