This study was designed to evaluate the effects of some root - promoting substances on rooting andmini tuber formation using vine cuttings obtained from two genotypes (TDr 335 and TDr 93 - 49) of whiteyam (D. rotundata). The ashes were obtained from rice straw, bamboo, Gliricidia sepium, dry leav...

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...

Yam cultivation in dry season was tested in the farmer’s field at inland valley in Niger state, Nigeria. Water yam (Dioscorea alata) variety TDa 95/00328 had the greater response to the gibberellin inhibitor prohexadione-calcium (PC). The sprouting period of PC treated tuber was 21 – 27 days at D...

Scarcity of seed, pest and diseases are major constraints to yam production. Tissue culture techniques of meristem culture combined with heat therapy have been used to produce high-yielding virus-tested plantlets of root crops, which are later multiplied through micropropagation. However, the mic...

The genus Dioscorea is considered to be one of the most difficult groups for cyto-taxonomic studies because of the large number and small size of the chromosomes. The objective of the present study was to develop an efficient method of chromosome observation by identifying the optimum time for co...
