“…Bud or spear rot (BR) disease is the most destructive disease of oil palm in South America comprising Ecuadorian Amazon, Brazil, southwest Colombia, and Suriname. The disease also has been reported in India and parts of Africa [71]. Bud rot in oil palms can manifest differently depending on the prevailing environmental conditions.…”

Oil palm crops are the most important determinant of the agricultural economy within the segment of oilseed crops. Oil palm growing in their natural habitats are often challenged simultaneously by multiple stress factors, both abiotic and biotic that limit crop productivity and are major constraints to meeting global food demands. The stress-tolerant oil palm crops that mitigate the effects of abiotic stresses on crop productivity are crucially needed to sustain agricultural production. Basal stem rot threatens the development of the industry, and the key to solving the problem is to breed new oil palm varieties resistant to adversity. This has created a need for genetic improvement which involves evaluation of germplasm, pest and disease resistance, earliness and shattering resistance, quality of oil, varieties for different climatic conditions, etc. In recent years, insights into physiology, molecular biology, and genetics have significantly enhanced our understanding of oil palm response towards such stimuli as well as the reason for varietal diversity in tolerance. In this review, we explore the research progress, existing problems, and prospects of oil palm stress resistance-based physiological mechanisms of stress tolerance as well as the genes and metabolic pathways that regulate stress response.

Leaf spot disease, particularly Curvularia leaf spot (CLS), can devastatingly damage both quality and quantity of oil palm seedlings in Thailand. Chemical fungicides have been intensively applied to control transmission of this disease. However, this has relatively low efficiency as the causative pathogen gains resistance to fungicides with selection pressure. An alternative or complementary cost-effective and environmentally friendly approach is necessary to find the resistant varieties for disease management. In this present study, a total of 122 lines of Dura female plant, 2 lines of Pisifera male plant, and 4 Tenera commercial varieties (A, B, C and SUP-PSU1) were screened by Curvularia inoculation using detached leaf method. Two weeks after inoculation, the results showed 13 Dura lines as highly resistant to CLS (0% disease incidence), whereas one line (129) and the commercial variety B were highly susceptible (100% disease incidence). Nine Tenera hybrid lines from 13 Dura highly resistant lines were selected to test for high resistance and subjected to Curvularia inoculation in greenhouse conditions, and compared with the susceptible and highly susceptible lines. Three Tenera hybrid lines (138, 187 and 203) showed high resistance to CLS significant difference from susceptible lines. These were the most highly resistant varieties to CLS and should be considered for breeding programs of oil palm stock among the cases tested.

“…Ces gommes peuvent obstruer entièrement la lumière du vaisseau et bloquer complètement la circulation de la sève, ce qui entraîne un dépérissement plus ou moins rapide des palmiers atteints (Flood, 2006 ;Tengoua et Bagkoumé, 2008). Cette maladie occasionne la mort de plus de 70% des palmiers en plantation (Cooper, 2011 ;Ntsomboh et al, 2012). La méthode de lutte mise en place pour faire face à ce pathogène a été essentiellement d'origine génétique; la lutte chimique étant quasiment impossible à cause de l'origine tellurique du pathogène.…”

“…Elle repose sur le choix du matériel végétal résistant après un test d'inoculation de l'agent pathogène aux plantules au stade prépépinière (Allou et al, 2003). En effet, le matériel testé est dit résistant lorsque l'indice de la maladie est inférieur à 100 et sensible lorsque l'indice est supérieur à cette valeur (Ntsefong et al, 2012). Cependant, cette méthode est consommatrice de temps et utilise un nombre important de matériel végétal.…”

RESUMEEn Afrique, la culture du palmier à huile est menacée par la fusariose causée par Fusarium oxysporum f. sp. elaeidis (F.o.e). Chez cette plante, l'activité antifongique des phytoalexines a été démontrée dans la lutte contre ce champignon au cours des premières semaines après inoculation. L'objectif de cette étude est de sélectionner des clones de palmier à huile résistants à F.o.e. sur la base de leur synthèse phénolique. Pour ce faire, les racines blessées des plantules ont été inoculées par F.o.e et les non inoculés ont servi de témoin. Les racines ont été prélevées à différents temps. Les extraits racinaires des plantules ont été dosés par le réactif Folin Ciocalteu pour quantifier les phénols totaux des plants inoculés (IT) et non inoculés (NI). Les résultats ont montré que les clones résistants ont réagi à l'infection dès le premier jour après inoculation. Par contre, les clones sensibles ont réagi le cinquième jour. Au huitième jour, la quantité de phénols baisse considérablement chez les clones sensibles et augmente ou se stabilise chez les clones résistants. Ce résultat pourrait servir pour la sélection des clones résistants à F.o.e avant la mise au point des marqueurs phénoliques de tolérance du palmier à huile à ce pathogène. © 2016 International Formulae Group.

Phenolic reaction of four clones of oil palm inoculated by fusarium oxysporumf. sp. elaeidis D. B. F. GOGBE et al. / Int. J. Biol. Chem. Sci. 10(2): 486-496, 2016 487 ABSTRACTIn Africa, the cultivation of oil palm is threatened by Fusarium oxysporum f. sp. elaeidis which is responsible of the fusarium. The antifungal activity of phytoalexins was demonstrated in the fight against this fungus in the first weeks after inoculation of the oil palm plant. However, the phenolic behavior of sensitive and tolerant clones over time remains unclear. The objective of this study is to select resistant oil palm clones F.o.e. on the basis of their phenolic synthesis. In order to achieve this aim, the roots of the oil palm plants were injured and inoculated with F.o.e. The uninoculated oil palm plants were used as the control. The roots were collected at different times. The root extracts of the oil palm plants were measured using the Folin Ciocalteu reagent in order to quantify the total phenols present in both the inoculated (IT) and the non-inoculated (NI) plants. The results showed that the tolerant clones reacted to infection from the first day after inoculation. On the other hand, the sensitive clones reacted the fifth day. On the eighth day, the amount of phenols was found to be significantly lower in the ...
