“…This has been confirmed from the fact that some cultivars with specific colour produced higher mutation rate and spectrum 4 . Such observations have been reported earlier [67][68][69][70][71][72][73] . Pigment analysis of a large number of mutant/hybrid ornamentals confirmed qualitative and/or quantitative differences between the pigments of original and mutants/hybrids.…”

“…In roses, the colour of their petals is caused by cyanidin and pelargonidin, which in conjunction with carotene creates attractive red and rosy colouration of flowers. However brown colouration is mainly caused by delphinine conjunction with carotenoids [48]. As far as anthocyanins are concerned, in roses 3-glucosides and 3-rhamnosides of pelargonidin, cyanidin, delphinidin are identified [49].…”

Edible flowers have become very popular in recent years as a potent and natural source of various important minerals, vitamins, flavonoids, enzymes and aromatic compounds. Various anti-bacterial, anti-viral, anti-fungal & anti-inflammatory substances have been found in various edible flowers e.g. Rose, Marigold, Lilac, Chrysanthemum, Chinese hibiscus, Roselle, Tulip, Magnolia, Water lily etc. These flowers are almost calorie-free, high in antioxidants, have inhibitory effects against cancer, obesity and inflammation, prevent neuronal degradation, help to diminish blood pressure, demonstrate gastro-protective and hepato-protective effects. Edible flowers show antioxidant activities, inhibitive activities on free radicals and ROSscavenging properties due to presence of various phenolic compounds e.g. Quercetin, Rutin, Gallic acid etc. Pollen, nectar and petals are rich source of proteins, carbohydrates, lipids. The colour of flowers is characterized by various carotenoids, anthocyanins etc. Harvesting of edible flowers should be done in cool climate during day time in fully bloomed condition to retain quality and shelf-life. Edible flowers are generally used in salads, soups, beverages, and herbal medicines across the world. People with conditions like hay fever, allergies or asthma must be careful in consuming these flowers. However, in upcoming years, there are immense possibilities of a rapid increase in the consumption of edible flowers when cultivated organically.

“…Согласно более ранним биохимическим исследованиям рода Tulipa, красные, розовые, оранжевые, пурпурные и лиловые оттенки в листочках околоцветника тюльпанов обусловлены присутствием антоцианов, тогда как за желтые оттенки ПОВОЛЖСКИЙ ЭКОЛОГИЧЕСКИЙ ЖУРНАЛ № 2 2022 отвечают каротиноиды (van Eijk et al, 1987;Nieuwhof et al, , 1990Yuan et al, 2013). Молекулярный механизм формирования окраски околоцветника сортовых тюльпанов (Tulipa gesneriana L.) разного цвета представлен в работе Wang с соавторами (2022).…”

The range of the polychromous Tulipa suaveolens Roth comprises almost the whole Ponto-Caspian Steppe, from the south-east of Ukraine to western Kazakhstan. High variation in flower color is a unique feature of this species, but features of its geographical distribution remain unclear. We studied T. suaveolens tepal color variation in 56 natural populations across the European range. Tepal colors were detected from digital images using the Lab color model with two chromatic components, a (red color intensity) and b (yellow color intensity). A conclusion was made that, throughout the European range, an obvious T. suaveolens flower color gradient is expressed in the direction from the south-west to the north-east, along which the red chromatic component intensity decreases. A similar gradient is observed when the height above mean sea level increases. The chromatic component a was shown to have a spatial autocorrelation and to depend on the long-term bioclimatic environmental parameters, temperature and precipitation. Thus, the identified geographical trends in the T. suaveolens flower color distribution across the studied part of its range are a consequence of natural selection caused by these two abiotic factors.
