Impact of Climate and Ecological Habitat Variation on Chrysophyllum albidum G. Don: Morphological Traits and Population Patterns

June 19, 2021 Agricultural Sciences 0

Chrysophyllum albidum is a tropical forest species that plays a significant socioeconomic role in West Africa due to the high consumption and trade of its fruits. In order to contribute to the species domestication, the morphological variation and ecological structure of Chrysophyllum albidum G. Don were assessed in Benin. Dendrometric parameters like diameter at breast height, total height, and bole height were measured in 120 individual trees from two ecological zones and four different provenances. Furthermore, for 1,800 fruits and seeds, morphometric parameters such as fruit length, fruit width, fruit weight, seed length, seed width, and seed weight were measured. The distribution of C. albidum diameter and height classes in each ecological zone, when adjusted to the Weibull distribution, revealed a bell-shaped curve with left dissymmetry, which is typical of young stands (form coefficient between 1 and 3.6). There was no differentiation found using principal component analysis, indicating that accessions from different agroecological zones were morphologically similar. However, morphometric data analysis of variance revealed some significant differences. In terms of bole height (P =.000) and fruit and seed size (P =.021), there is a significant difference between agroecological zones and provenances. Although morphological variability in C. albidum between provenances and agro-ecological zones is low, there are pathways for selection purposes because bole height, fruits, and seed weight exhibited significant morphological variability among agro-ecological zones.
