Comparative Evaluation of Physico-chemical Characteristics of Flours from Steeped Tubers of White Yam (Dioscorea rotundata Poir), Water Yam (Dioscorea alata L.) and Yellow Yam (Dioscorea cayenensis Lam)
The study examined Yam Tuber Species (YTS), Tuber Steeping Duration (TSD) and Flour Particle Size (FPS) as factors of flour. Data were collected using white yam, water yam and yellow yam steeped in water (30 ± 2 °C, pH 6.78) and withdrawn, and the flour classified, and analyzed for each parameter. Results obtained showed that all the test parameters, Water Retention Capacity (WRC), Swelling Ind...

the species of dioscorea (yam) are regarded as a staple food crop for millions of people in the tropical and subtropical regions of the world. it is regarded as an important food crop next to cereals and grains due to high yield storage of carbohydrates. economically, only few species are recognized for cultivation from agricultural point of view, in spite of its large species diversity. the sp...
متن کاملPhases of dormancy in Yam tubers (Dioscorea rotundata).
BACKGROUND AND AIMS The control of dormancy in yam (Disocorea spp.) tubers is poorly understood and attempts to shorten the long dormant period (i.e. cause tubers to sprout or germinate much earlier) have been unsuccessful. The aim of this study was to identify and define the phases of dormancy in Dioscorea rotundata tubers, and to produce a framework within which dormancy can be more effective...
متن کاملEvolution and Phylogenetic Diversity of Yam Species (Dioscorea spp.): Implication for Conservation and Agricultural Practices
Yams (Dioscorea spp.) consist of approximately 600 species. Presently, these species are threatened by genetic erosion due to many factors such as pest attacks and farming practices. In parallel, complex taxonomic boundaries in this genus makes it more challenging to properly address the genetic diversity of yam and manage its germplasm. As a first step toward evaluating and preserving the gene...
متن کاملHarnessing modern biotechnology for tropical tuber crop improvement: Yam (Dioscorea spp.) molecular breeding
Yams (Dioscorea spp.) constitute a staple food crop for over 100 million people in the humid and subhumid tropics. They are polyploid and vegetatively propagated. The Guinea yams, Dioscorea rotundata and D. cayenensis, are the most important yams in West and Central Africa where they are indigenous, while D. alata (referred to as water yam) is the most widely distributed species globally. The g...
