Assessing Morphological Traits Variation and Fruit Production of Lophira lanceolata (Ochnaceae) in Benin
Abstract: Lophira lanceolata is an oleaginous tree species whose fruit is used for vegetable oil production in Benin. The present study highlighted the fruit production and characterization of the morphological traits of the fruits and seeds of this species. A total of 196 mature trees in production were randomly sampled in Borgou-Nord, Borgou-Sud and Atacora Chain phytodistricts. Descriptors were characterized globally at the level of phytodistricts surveyed. Pearson correlation test stands out the relationships between the different descriptors. The effect of phytodistricts on fruit production was analyzed using a Generalized Linear Model (GLM) and the variation of morphological traits between phytodistricts was examined through Kruskal-Wallis test. Finally, SMA regression was used to test the influence of the phytodistrict on the relationship between L. lanceolata seed and fruit weight. This study revealed that there is a positive and significant correlation between the morphological traits of fruits and those of seeds. Trees descriptors (e.g. total height, diameter at breast height, and leaf petiole length) predict fruit production of L. lanceolata, but are not significantly correlated with fruit and seed traits. In the Atacora Chain phytodistrict, breeding trees are entering production with small diameter, low height and produce little number of fruits per tree with higher weight, unlike the Borgou-Nord and Borgou-Sud phytodistricts. These results can be useful in the selection of early breeding tree in Atacora Chain phytodistrict and high-yielding trees from individuals in the Borgou-Nord and Borgou-Sud phytodistricts.
