THE EFFECT OF PRETREATMENT METHOD OF SEED GERMINATION ON EARLY GROWTH OF PARKIA BIGLOBOSA (African Locust Beans).

Abstract

The effect of temperature regulation and chemical, mechanical scarification of seed germination of Parkia biglobosa were carried out, after collecting seed of P.biglobosa from the mother tree. The deed treated by using sand paper (scarification), sulphuric acid (chemical), temperature ( hot water), cool water and the untreated which is (control)were planting in the botanical garden. The result obtained show that there was a significance difference in daily temperature and the highest percentage of germination recorded was 70% when seeds were scarified by filling around circumference and at the micropyle. The article was devoted for analyzing the effects of different applied pre-treatments to African locust bean seeds on technical efficiency of this design mechanical scarification
