Analysis of antitranspirant chemicals in relation to the post-harvest attributes of cut rose CV. Naranjo

Abstract

In order to evaluate the effect of some antitranspirants on the post harvest attributes of cut rose cv. Naranja an experiment was conducted in the laboratory of Department of Horticulture, GBPUAT, Pantnagar. The experiment was arranged in factorial completely randomized block design with different concentrations of antitranspirants ( Glycerol, MgCO3, Paclobutrazol ) as one factor and storage durations (0, 3, 6, 9 days ) as other. The results significantly revealed that foliar application of 8% glycerol increased the vase life to about 3 times as compared to control. Also this was accompanied by minimum water uptake and water loss and appearance was improved by the application of it. Stomata opening which serve as portals for both loss of water vapour and for the intake of CO2, was also decreased by the application of 8% glycerol and this is correlated with minimum transpiration rate recorded in those flowers.
