Antifungal properties of yam (Dioscorea alata) peel extract

Folia Microbiologica, 1996
The extraction of natural antifungal compounds from the peels of yam (Dioscorea alata) and the effect of these compounds on both the vegetative and reproductive structures of some yam not pathogens were studied. Four prominent antifungal components were obtained; one of the components was fully characterized and identified as beta-sitosterol.

Influence of nitrogen and potassium inputs on plant biomass and nitrogen use efficiency of Dioscorea alata

Journal of plant nutrition, 2022
Nitrogen (N) and potassium (K) are known to be important for root and tuber crops but their interactions have not yet been studied in Dioscorea spp. A field experiment was conducted on a Luvisol, in Sri Lanka, over two consecutive seasons in 2013/14 and ...

Gelling properties of extruded yam ( Dioscorea alata ) starch

Food Chemistry, 1999
Yam (Dioscorea alata) starch was pregelatinized in a single screw extruder. Response Surface Methodology was used to study the effect of extrusion variables: feed moisture (18, 21, 24%), extruder temperature (120, 150, 180°C) and die diameter (3, 4, 5 mm) on cold viscosity, gel-forming capacity and retrogradation of extruded starches.

Occurrence of hexaploid males in Dioscorea alata L.

Euphytica, 1998
In the polyploid species Dioscorea alata, earlier studies have shown a prevalence of higher ploidy levels (2n = 60 and 80) restricted among female clones. Cytological screening of a number of rare flowering collections maintained at the CTCRI revealed the occurrence of hexaploids (2n = 60) among male clones for the first time.

Genetic relationships between Dioscorea alata L. cultivars

Genetic Resources and Crop Evolution, 1998
Isozyme variation was studied to determine genetic relationships among 269 cultivars of Dioscorea alata originating from the South Pacific, Asia, Africa and the Caribbean. Four polymorphic enzyme systems (MDH, PGI, SkDH, 6PGD) revealed 66 isozyme phenotypes, or zymotypes, each uniquely characterized by the presence or absence of 27 electromorphs ...

Floral biology and artificial pollination in Dioscorea alata L.

Euphytica, 1990
Floral biology of Dioscorea alata L. was studied. Anthesis occurred in male flowers by 12.30 h and in female flowers between 13.00 h and 14.30 h. Male flowers remained open for 4–5 hours and female flowers for 9–11 days.
