Abstract
The investigation entitled “Standardization of tinting techniques in gladiolus gerbera and carnation” was carried out in the laboratory of the Department of Post Harvest Technology, KRC College of Horticulture, Arabhavi, University of Horticultural Sciences, Bagalkot during the year 2018-2019.
An investigation was conducted to standardize the colours and time of immersion to perform the tinting techniques in the gerbera, carnation and gladiolus. Wide range of variations were observed among the different treatments with respect to physiological and bio-chemical and post harvest quality parameters.
Among three flowers treated with distilled water and immersed for 2.5 hrs duration recorded significantly higher vase life, volume of water uptake, moisture, relative water content, carbohydrates, phenols, peroxidase and catalase activity along with least physiological loss in weight. Intensified xylem colouration was observed in the flowers which were treated with blue, green, yellow and orange for 7.50 hourrs and it was lower in Pink colour for 7.50 hours.
Using different colour combination and immersion time in gerbera and carnation flowers treated with distilled water and immersed for 7.50 hrs had exhibited higher values of vase life, volume of water uptake, moisture, relative water content, carbohydrates, phenols, peroxidase and catalase activity along with least physiological loss in weight and least was found in yellow and pink combination flowers immersed for 12.50 hrs. The intensified xylemic patterns flowers tinted with orange and green, blue and green, yellow and orange combinations which were immersed for 12.50 hrs were found to be superior ins dual colour tinted gerbera and carnation flowers and based on sensory evaluation these colours attracted the consumer preference.
