Abstract

When pieces of Dioscorea dumentorum, Dioscorea alata and Dioscorea cayenensis were inoculated with suspensions of Botryodiplodia theobromae and Aspergillus niger and incubated at room temperature, the quantities of carotenes and xanthophylls were decreased by infection. The quantities of carotenes and xanthophylls were highest in D. dumentorum followed by D. cayenensis; D. alata had the lowest amounts.
