VARIETAL VARIABILITY OF ARGAN TREE FOLIAGE ARGANIA SPINOSA (L) SKEELS IN VARIOUS BIOCLIMATIC STAGES IN ALGERIA

Beladjemi Samira, kechairi Réda

Abstract


The study of the morphological difference of 628 leaves of the argan tree Argania spinosa (L.) Skeels was carried out by subjective sampling after a period of field data collection in spring 2017 through the various wilayas: Mascara, Mostaganem, Algiers, Bechar, Adrar, Tindouf. The objective was a varietal identification of foliage through the bioclimatic stages. However a measurement of two biometric criteria (length and width) was carried out, which shows a differentiation of forms between the samples studied by the significant differentiation at which with a low correlation R² = 27.2%, the effect of climate on the shape of the leaves is noticeably well represented.
