RESPONSE OF Khaya senegalensis (Desr.) SEEDLINGS TO PLANT HORMONES
Keywords:
Indole-3-Acetic acid, Kinetin, Early growth, Khaya senegalensisAbstract
Khaya senegalensis is valued for its wood qualities, beautiful figurative timber grains, brown colour, and use for production of quality furniture and household utensils. This study assessed the early growth response of Khaya senegalensis seedlings to four different treatments: Indole-3-Acetic acid (A), Kinetin (K), 50:50 Kinetin and Indole-3-Acetic acid (KA), and control (C). The hormones were assessed at four concentrations (doses); 1 mg/ml (P1), 3 mg/ml (P3), 5 mg/ml (P5) and 7 mg/ml (P7). The treatments were applied on the leaves and stems of seedlings and total height, collar diameter, number of leaves and leaf area were monitored. The hormonal type and dose significantly affected seedling height and collar diameter. The interaction effects had a significant influence on leaf area and height of seedlings. The 50:50 Indole-3-Acetic acid and Kinetin combination at 1 mg/ml yielded the highest height (14.03 cm), collar diameter (1.79 mm) and number of leaves (8). This could have positive implications in nursery production of Khaya senegalensis seedlings.
