Cocoyam (Xanthosoma sagittifolium L. Schott) is an important staple tuber crop for tropic populations and consists of three cultivars with different productivity. In vitro tuber induction of a broad range of genotypes could be a very useful way to propagate and increase valuable cocoyam. Shoot tips were cultured on a multiplication medium containing MS(More)
Direct plant regeneration, multiple shoot formation and callogenesis were induced from cocoyam shoot tips cultured in vitro. At different stages of culture, phenol content, peroxidase activity and acidic soluble isoperoxidase patterns were analysed in plantlets. Results showed that phenol content of plantlets cultured on auxin-free media decreased with(More)
The root rot disease caused by Pythium myriotylum is responsible for about 70% of cocoyam production loss in Cameroon. The potential of benzo-(1,2,3)-thiadiazole-7-carbothioic S-methyl ester (BTH) to trigger resistance in cocoyam (Xanthosoma sagittifolium) plants against P. myriotylum was investigated. Under controlled conditions, BTH was an efficient(More)
