Clonal propagation of Detarium microcarpum and Khaya senegalensis

摘要: The slow growth of seedlings and the impact insect pests are major limitations to use indigenous species in plantations Burkina Faso. Thus, vegetative propagules resistant clones may enhance success plantations. objectives this thesis were develop efficient simple clonal propagation methods for two species, Detarium microcarpum Khaya senegalensis, compare sexual asexual propagules. Two developed: root cuttings D. stem K. senegalensis. Root segment length diameter key factors that affect sprouting rooting ability. segments 20 cm 15-60 mm most successful. Stockplant auxin application influenced formation by leafy High proportions taken from seedling have rooted, while obtained older trees rooted poorly, highlighting maturation as critical factor. ability was improved pollarding application. Comparison plantlets revealed suckers sprouts had a closer morphological resemblance. well-established system high carbohydrate concentrations roots favor comparable suckers. Seedlings stecklings senegalensis similar patterns with respect to: relative rates length, leaf, stem, total plant biomass; biomass fraction root; leaf area productivity; foliar carbon isotope ratio; roots. However, water stress growth-limiting factor, resulting reduction growth, production, concentration. As these studies constitute first step toward effective ensure successful plantation, more investigations examining effects donors, regulators required order optimize techniques.
