Temporal Variation of Seedling Growth and Leaves Type of Four Morphotypes of Lannea Microcarpa Engl.& K. Krause in Burkina Faso

Abstract

This study evaluated the growth performance and the leaves type of seedlings from different morphotypes of Lannea microcarpa in the central plateau of Burkina Faso.Then, seeds of Lannea microcarpa were collected from four (4) morphotypes based on their botanical characters and noted as NLs: Lannea sp. from Naab-Mayooghin, MLs: from Mamousyorgo 1, MaLs: from Mamousyorgo2, ZLs: from Ziniaré. One hundred seeds per morphotypes were used for the seedlings production in nursery through sowing by using a randomized block design. The leaves type of the produced seedlings was investigated by visual observation. Significant differences in the growth traits of the seedlings were found among the four morphotypes (p < 0,05). The height and the collar diameter of the seedlings were found to be higher in NLs, MaLs and ZLs than those in MLs. Regarding the leaves, it was observed different types among the morphotypes. Seeds from NLs and MLs produced seedlings with both compound and simple leaves while those from ZLs and MaLs produced seedlings with only compound leaves. Generally, all morphotypes exhibited a relatively high growth with production of different types of leaves.

Characterization of Atypical Individuals of &lt;i&gt;Lannea&lt;/i&gt; in Burkina Faso

“…This highlighted that these individuals are of the same kind. These results confirmed those obtained from the morphological characterization previously carried out by [5]. The sequencing of the various genes allowed the grouping of the individuals into several subgroups.…”

“…According to surveys of residents, these trees are between 80 and 90 years old. However, these individuals exist in small numbers (4 trees) and do not seem to have been encountered elsewhere [5]. Studies have shown that these individuals come from the same ecological environment as Lannea microcarpa [6].…”
