Modification of Flower Color Pigments and Color Composition with Hormonal Treatments and Sucrose in Tulipa gesneriana ‘Kingsblood’
Three separate experiments were conducted to investigate the interplay between three phytohormones and sucrose for the change of flower color composition and the plant secondary metabolites in Tulipa. The variations of the physiological and morphological characteristics, with ABA at 5 and 10 mg/L (as experiment one), GA3 at 300 and 500 mg/L (as experiment two), 50 and 10...
متن کاملFTIR study of primate color visual pigments
How do we distinguish colors? Humans possess three color pigments; red-, green-, and blue-sensitive proteins, which have maximum absorbance (λmax) at 560, 530, and 420 nm, respectively, and contribute to normal human trichromatic vision (RGB). Each color pigments consists of a different opsin protein bound to a common chromophore molecule, 11-cis-retinal, whereas different chromophore-protein i...
متن کاملPlant carotenoids: pigments for photoprotection, visual attraction, and human health.
Plant carotenoids are red, orange, and yellow lipid-soluble pigments found embedded in the membranes of chloroplasts and chromoplasts. Their color is masked by chlorophyll in photosynthetic tissues, but in late stages of plant development these pigments contribute to the bright colors of many flowers and fruits and the carrot root. Carotenoids protect photosynthetic organisms against potentiall...
متن کاملFour cone pigments in women heterozygous for color deficiency.
It is generally accepted that human color matching is trichromatic (requires three primaries) because there are three types of cone, each containing one visual pigment. A color match between two stimulus fields is thought to be determined at the receptor level where the rate of quantum absorption by each of the three cone pigments must be equated to obtain a color match. Since there are three c...
متن کاملCarotenoids and their isomers: color pigments in fruits and vegetables.
Fruits and vegetables are colorful pigment-containing food sources. Owing to their nutritional benefits and phytochemicals, they are considered as 'functional food ingredients'. Carotenoids are some of the most vital colored phytochemicals, occurring as all-trans and cis-isomers, and accounting for the brilliant colors of a variety of fruits and vegetables. Carotenoids extensively studied in th...
