Investigating a new cryopreservation protocol for yams ( Dioscorea spp.)

Plant Cell Reports, 2003
Experiments were initiated to develop protocols for four species of Dioscorea, namely D. bulbifera L., D. oppositifolia L., D. alata L. and D. cayenensis Lam., and to assess the effects of various factors on the survival and regrowth of explants after rewarming.

Macromolecular characteristics of ten yam (Dioscorea spp) starches

Journal of the Science of Food and Agriculture, 2003
AbstractStarches from ten yam (Dioscorea) species were compared with those of maize, wheat, potato and cassava, and characterized by high‐performance size‐exclusion chromatography coupled with multiangle laser light scattering. Treatment with 95% (v/v) dimethylsulphoxide and microwave heating in a high‐pressure vessel led to complete dissolution of the

YAM (Dioscorea spp.) FLOUR FORTIFICATION WITH SOY FLOUR

Journal of Food Science, 1977
ABSTRACT Yam flour was fortified with soy flour, rehydrated to a doughy consistency, and tested for resistance to extrusion, color and panel preference. The food product was similar to pounded yam “fufu” which is popular in West Africa.

Trace metals in tropical yam species: Dioscorea spp.

Food Chemistry, 1994
Abstract Four common species of Dioscorea; D. piscatorium, D. wallichiani, D. hispida and D. alata were analysed for the trace metals using the technique of Instrumental Neutron Activation Analysis (INAA). A total of sixteen elements were detected some of which are classified as either toxic or essential to humans.

Preharvest microbial rotting of yams (Dioscorea spp.) in Nigeria

Transactions of the British Mycological Society, 1972
Symptoms of three distinct types of preharvest tuber rot of four species of yams (Dioscorea rotundata, D. data, D. cayenensis and D. dumetomm) are described. The diseases include a dry rot in which the bark and some underlying tissues become crumbly ; a soft rot in which internal tissues become soft and brownish to pinkish; and a watery rot in which ...

The distribution of diosgenin in Dioscorea spp

Annals of Applied Biology, 1966
SUMMARYThe distribution of diosgenin in Dioscorea deltoidea Wallich and D. sylvatica Ecklon at successive stages of growth is described. Diosgenin occurs in the cotyledon‐endosperm of the dormant seeds, and in the tubers, roots, stems and leaves of plants from the seedling stage onwards.

Stimulating Axillary Buds in Yams (Dioscorea SPP)

Experimental Agriculture, 1978
SUMMARYA method is described of inducing many ‘eyes’ on yam tubers to sprout, and of using the sprout-bearing segments as propagules for establishing yam fields. The number of such propagules obtainable from a tuber depends on its size, but the method greatly increases the rate of propagation and holds special promise for both breeding and commercial ...
