Effect of glycerine for drying of cut foliage of Peltophorum ferrugineum

Abstract

Drying flowers is a rewarding experience because it is easy to do, the flowers usually dry remarkably well, and they last for many years. Preserving plant material with glycol is called glycerinisation. In this technique, the internal moisture of plant parts is replaced with solvents glycol to retain their original texture, shape and colour. Leaves preserved through glycerine are less prone to shattering and mechanical damage and more natural in appearance. The study was carried out to assess the effect of glycerine for drying of cut foliage of Peltophorum ferrugineum by two methods of glycerinisation (uptake, full dip) with different concentrations of glycerine (10, 20 and 40%). The leaves treated in T4M2 (40% glycerine solution by full dip method) articulated minimum change in leaf area (8.73%), minimum percentage of leachate (78.69%), maximum score on textural quality (4.44), shape retention (4.67), brittleness (5.00) and overall acceptance (4.71).
