The role of phenolic compounds in the determination of wilt disease tolerance of oil palm (Elaeis guineensis JACQ)

Diabaté S., De Franqueville H., Adon B., Coulibaly O., Ake S.. 2009. African Journal of Biotechnology, 8 (21) : 5679-5690.

Oil palm defence reaction to the vascular wilt disease was characterized by the production of phenolic compounds in the roots and pseudobulbs infected at the prenursery stage. The study was aimed at discriminating between tolerant and sensitive ones by the phenolic reaction of the roots and pseudobulbs after their infection with the Fusarium oxysporum f.sp.elaeidis, the pathogenic agent of vascular wilt disease of oil palm. Principal Component Analysis (PCA) and Discriminant Analysis (DA) show that although the phenolic metabolism was different in both organs; all the phenols belonged to the flavonoids and can be used to distinguish the tolerant clones and sensitive ones.
