Identification of soil factors that relate to plant parasitic nematode communities on tomato and yam in the French West Indies
A soil and nematode survey of tomato and yam crops was made in Martinique (French West Indies). Each sample was divided into two parts, one for the nematode study and one for the soil analysis. The coupling of the data was made using the coinertia analysis. For tomato plants, which were grown from seeds, the nematode-soil relationships were very strong. For the two varieties of yams, Dioscorea ...
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 Data were collected using white yam, water yam and yellow yam steeped in water (30 ± 2 °C, pH 6.78) and withdrawn, and the flour classified, and analyzed for each parameter.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...
متن کاملDistribution, management and diversity of yam local varieties in Brazil: a study on Dioscorea alata L.
Widely spread in the tropics, yams were introduced into Brazil during the colonial period and are currently grown throughout the country. Despite its importance as a pharmacological and food source, there is a lack of studies describing how and where this tuber is grown in Brazil. The aim of this study was to provide an overview of the cultivation and distribution of Dioscorea alata in differen...
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...
