Extraction and Determining the Dyeing Potential of Floral Dyes on Various Fabrics | Chapter 07 | Innovations in Science and Technology Vol. 2

 With the increased emphasis on the use of eco-friendly and biodegradable materials in recent years, extensive research work on the application of natural dyes in the textile industry has been performed around the world. Flowers are grown in large quantities in India. These flowers are used for decoration or as sacrifices to God, after which they are either dropped in water or simply abandoned, resulting in pollution. These discarded blooms can be utilised to create a natural dye. Natural dyes are frequently utilised in the textile sector, as well as in the production of Herbal Gulal (Abil), Colorful Candles, and the food industry. The goal of this research is to extract various dyes from Marigold (Tagetes erecta), Bougainvillea, and Indian Almond Leaves (Terminalia catappa) using an aqueous extraction method, and then apply the final extracted dye to various textile materials such as cotton, silk, and wool using various mordants such as Stannous Chloride, Ferrous Sulphate, Potassium dichromate, Copper Sulphate, Aluminium Sulphate, Sodium Chloride, Nickel Yellowish Orange, Reddish Pink, Yellow, and Green were the final colours of various extracted dyes. The final colour of the natural coloured fabric was yellow, green, brown, greyish, and purple.

Yam (Dioscorea spp) Genetic Variability Enhancement Using Its’ True Botanical Seeds | Chapter 12 | Current Topics in Agricultural Sciences Vol. 2

 Yam (Dioscorea spp.) is propagated vegetatively from its areal and underground tubers. Its development effort, like that of many other vegetative propagated crops grown in the country, is carried out through the collection, characterisation, and evaluation of germplasms discovered in farmers' fields. The purpose of this study was to investigate yam (Dioscorea spp.) flowering and botanical seed germination in order to improve genetics and conserve the species. The research was carried out in Ethiopia's Gedio Zone, Wonago district. In this study, 60 yam clones from six different species were obtained from various key growing regions around the country. Botanical seeds from open pollinated fields exhibited a wide range of diversity. Male, female, and none blooming plants were found in 21, 12, and 27 genotypes, respectively, among 60 yam germplasms. This revealed that female yam plants are less common than male yam plants in the yam population. 85 percent of botanical seeds germinated in this study, resulting in healthy and vigorous yam seedlings. As a result, utilising botanical seeds obtained through open pollination, it is possible to increase yam genetic variety. It will, in reality, be an alternate method for conserving yam and other root and tuber crops germplasms with botanical seeds in order to reduce genetic degradation at field gene banks due to biotic and abiotic causes.
