Photocontrol of Dioscorea alanta plantlet growth
Light quality evaluations were conducted on yam (Dioscorea alata L. cultivar 'Oriental' ) plantlets to determine the potential usefulness of manipulation of the light environment in regulating growth. Eight-week old, in vitro grown yam plantlets were transferred to pots and treated in vivo with end-ofday (EOD) red (R) or far-red (FR) light. Also, nodal segments ofD. alata plantlets were culture...
متن کاملIn-Vitro Propagation of Dioscorea alata for Tyrosinase Production
Article history: Received on: 27/11/2016 Accepted on: 29/12/2016 Available online: 20/03/2017 The copper-containing metalloprotein tyrosinase catalyzes the oxidation of tyrosine in particular L-DOPA to L-Dopaquinone that generates brown pigments in the wounded tissues. The industrial demand for tyrosinase enzyme is increasing as they have a wide range of applications in the field of environment...
متن کاملGrowth and Distribution of Roots of Dioscorea Alata L. Do Not Respond to Mineral Fertiliser Application
Water yam (Dioscorea alata) is a staple crop for many of the poorest in the tropics. Yam tuber response to fertiliser application has been reported to be erratic. We hypothesised that this variable response could be due to the development of a suboptimal root system that would not allow the plant to capture the nutrients added with the fertiliser. To verify this hypothesis we studied during two...
متن کاملNew microsatellite loci for water yam (Dioscorea alata, Dioscoreaceae) and cross-amplification for other Dioscorea species.
PREMISE OF THE STUDY Dioscorea alata L. is one of the most widely distributed species of the genus in the humid and semihumid tropics and is associated with traditional agriculture. Only a few microsatellite markers have been developed so far for this and other Dioscorea species. METHODS AND RESULTS We isolated 14 codominant polymorphic microsatellite markers using a microsatellite-enriched g...
متن کاملComparative 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 Data were collected using white yam, water yam and yellow yam steeped in water (30 ± 2 °C, pH 6.78) and withdrawn, and the flour classified, and analyzed for each parameter.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...
