The study accesses the responses of pre-sowing treatment on germination and also takes a critical look at the seedling characteristics and developmental pattern of formation and transition of juvenile to adult leaves in V. doniana. A total of 1800 fruits from 15 trees were collected from parts of North Central Nigeria (FCT and Niger State). Randomized Complete Block Design (RCBD) was adopted for the study and there were six sub treatments from two main treatments; namely chemical and hot water treatments. The seeds were subjected in to chemicals and hot water treatments at various degrees in order to speedy up the germination and break the dormancy of the fruit. The germination was recorded daily from the date of sowing and continued till the germination ceased. Chi-square (X2) test showed no significant difference between the treatments and the locations. The Least Significant Difference (LSD) showed no statistical significant of area of first pairs of leaf sizes across the three locations while LSD showed significant of petiole lengths between the three location. It was recorded that generally compound leaf formation ranges from two leaflets (bifoliolate) to five leaflets (pentafoliolate), the result shows that 50% of the plants selected for the study transited from simple to pentafoliolate compound leaf. Similarly, transition stage was between 7th and 8th leaf stage with majority (65%) of transition at 8th leaf stage. However, the study revealed that after interruption of already formed compound leaves i.e. cutting off the main apexes, majority (57%) of the seedlings reformed to simple leaves; hence, different leaf reformations were recorded.
