Effects of Different Pre- sowing Treatments on Seed Germination of African Grape (Lannea microcarpa L.)

Over-exploitation coupled with adverse effect of increased human activities and lack standard plantation endangers the germination Lannea microcarpa seeds. An experiment was carried out to check different pre-sowing treatments on seed African Grape (Lannea L.). Pot trials conducted during dry season at Botanic garden, Department Plant Science Biotechnology, Faculty Life Science, Federal University Dutsin-Ma, Katsina State using completely randomized design (CRD). Seeds were subjected three concentrations sulphuric acid, hot water, cold physical treatment untreated as control analyzed independently obtain best periods. To remove fungal spore exudate, a total nine hundred sixty (960) viable seeds selected surface sterilized in 1.0% Sodium-hypochlorite (NaOCl) for 1 minute rinsed (3) times sterile distilled water. 20 sown each polypot. In chemical treatments, maximum percentage (85.00%) early days seedling emergence (8.00 days) significant (P≤ 0.05) treated 50% dilute H2SO4 hour when compared other time intervals. Similarly, treatment, recorded full-sided scarification (6.00 days). Highest (90.00 %) immersed water 10 minutes (15.00 result did not produce significance differences (P> among except 8.00 hours (80.00%) These results suggested that days), used this study optimum inducing breakage coat technology could be applied generate future breeding programme.
