ABSTRACT Objective: To determine the characteristics of stomata parameters in Elaeis guineensis Jacq. Current. Methodology and results: Parameters such as the density, the length and with of stomata were evaluated by observing the leaf epidermis microscopically.

The results showed that on Journal of Applied Biosciences 104:9904 -9910 ISSN 1997-5902 Djinet et al . J. Appl. Biosci. 2016 Évaluation des caractéristiques des stomates chez le palmier à huile (Elaeis guineensis Jacq.) 9905 the underside of leaves, stomata density was greater in adult material 50.32 stomata per mm 2 than in younger material 23.88 stomata per mm 2 on the upper leaf surface this reverses stomata per mm 2 4.77 against 9.21 stomata per mm 2 . Stomata on the upper leaf surface are longer and wider than those seen on the underside of leaves for all materials. Stomata adult materials are also longer than those of young material. For all the parameters studied, the underside of leaves appears most indicated to characteristerize the stomata in the oil palm. Conclusion and application of results: this present study shows the importance of stomata in the characterization of the ploidy level of the oil palm. So, results can be applied in the research of plant with a more interesting fertility based on the polyploidization.
