RELATION OF FLOWER COLOUR, ANTHOCYANIN CONCENTRATION AND THE ENVIRONMENTAL FACTORSSUJATA MAHAPATRA, BHASKAR PADHY AND LATE PROF. PRASANTA KUMAR BEHERA
The anthocyanin pigments were extracted from different flowers like Hibiscus rosasinensis, a shrub of malvaceae family (the red colour flower), Rosa indica, a shrub of rosaceae family (pink colour flower), Clitoria ternatea (blue flower), a climber of fabaceae family, Lagerstroemia indica Purpleflower, a shrub of lythraceae family available in south eastern Orissa, using aquash methanol (0.1% acidified). The extracted pigments were exposed to environmental factors like different pH (1,4,7,10), different temperature (5 ºC,25 ºC,35 ºC & 45 ºC) and light and dark conditions. The result showed that increase in pH, temperature or exposure to light destruct the anthocyanin pigments. Red anthocyanin had the greatest resistance to destruction by these environmental factors, than the others
