Effect of Biocolours and Inorganic Dyes on OrnamentalDry Flower Grasses

摘要

The present investigations were carried out at Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2013-14. Bromus and Briza are the important introduced ornamental grasses which are used for making various products in dry flower industry. Different dyes like fabric, indicator, food and bio-colours were used to enhance the value of dried flowers for aesthetic beautification and product diversification. The findings revealed that among four different categories of fabric dye(yellow, dark green, violet and magenta pink) and indicator dye (Brilliant green, Eosin yellow and Crystal violet) were the excellent in performance. Dyes scored maximum for quality parameters even after ten months of storage. Quality parameters in caseof food dyes were medium to high at the time of dyeing but the colours faded very fast and retention was not good after ten months. Out of the bio-colours turmeric and [ilium pollens were quite satisfactory, whereas beet root and wild henna were very poor in performance.
