Expression of boron deficiency symptoms and link with the genotype in oil palm (Elaeis guineensis Jacq.)
Boron is an important trace element in the physiology of the oil palm. In the transport of carbohydrates, protein synthesis and energy transfer reaction, its deficiencies have spectacular effects. The deficiency occurs frequently in young trees, and in the most favourable ecologies in Indonesia in which the palms grow well. In a fertiliser trial implemented at P.T. Socfindo Aek Loba Estate with 4 different progenies closely genetically linked, a new type of Boron deficiency symptom appeared very early. Mainly this affected only one of the four progenies where the Boron deficiency status was recorded regularly. In fact, 3 types of symptoms of Boron deficiency have been recorded. It appears that the expression of Boron deficiency symptoms derives more from the genotype affected than the level of the element in the leaf. Observations recorded in commercial areas and in progeny trials, confirming the link between type of boron deficiency expression and genotype are also discussed.
