Journal Article 1994

Autor: Green, K. Simons, S.

A storage rot of yams (Dioscorea alata), commonly referred to as ‘dead skin′, has recently become a major constraint to yam production in the Caribbean. The fungal pathogen Colletotrichum gloeosporioides was consistently isolated from affected tubers and re‐inoculation of healthy yam tubers resul...

Anthracnose, caused by Colletotrichum gloeosporioides Penz., is the most severe foliar disease of water yam (Dioscorea alata) worldwide. Population genetic analyses can yield useful insights into the evolutionary potential of C. gloeosporioides and thus lead to the development of appropriate dise...

Growth of varieties of Dioscorea alata and D. rotundata were stunted when they were grown in nutrient solutions containing 5 to 60 mg l−1 Fe. In D. alata variety TDa 95/00361, plants grown in 60 mg l−1 Fe solution exhibited reductions of 29–65% in plant height, leaf length and width, number of le...

Single node cuttings from pathogen-tested in vitro plantlets of white guinea yam (D. rotundata), cultivar TDr 93–23, were cultured in tuberization and half- and full-strength Murashige and Skoog media with 5% or 8% sucrose, with or without agar, in light or darkness and at 25 or 18°C. Microtuberi...

This study examined the dynamics of fresh yam tuber prices and applied a hedonic pricing model to estimate the market values of tuber characteristics in two consumption centers in Togo. Real prices were modeled as a function of variables measuring yam species, physical attributes of tuber, origin...
