Screening cassava varieties for the linamarin-synthesizing enzyme complex activity

Pages 755-758 Dossou-yovo, Y. Chukwumah and M. Bokanga ABSTRACT Cassava breeding programs selecting for varieties with low amounts of cyanogenic glucosides usually rely on chemical tests, qualitative or quantitative, of cyanogenic compounds in cassava roots at harvest time. A recent approach is however based on an enzyme system that convert L-valine to cyanohydrin (immediate precursor […]

Agroecological determinants of cassava root taste and cyanogenic glucoside content: preliminary findings

Pages 723-729  Mkumbira, J; L. Chiwona-Karltun, J. Saka, A.R.K. Mhone, N.M. Mahungu, M. Bokanga; L. Brimer, H. Rosling & U. Gullberg ABSTRACT Cassava is grown m diverse agro-ecologies in tropical Africa. Cyanogenic glucosides (CG) in cassava is determined by both the genotype as well as the environment. Changes in cassava CG levels due to environmental […]

The dynamics of the accumulation of cyanogenic glucosides in cassava during its growth cycle.

Pages 711-719 Y. Chukwumah and M. Bokanga ABSTRACT The accumulation of cyanogenic glucosides in the cassava plant throughout its growth cycle was investigated. Results show that total plant cyanogenic glucosides content increases throughout the plant growth cycle. Cyanogenic glucosides content in the aerial parts (especially leaves and stem) were the major source of whole plant […]

Investigating the potential for vertical integration of primary cassava flour producers with secondary confectionary processors in Uganda

Pages 694-698 R.M. Gensi, M. Bokanga, A. Nayiga and R.S.B. Ferris ABSTRACT In many African countries, declining production has led to an increasing food deficit. This deficit has been met; to a large extent by an increasing cereal importation. These imports have a negative impact on both foreign exchange earning and internal production. To offset […]
