dc.description.abstractA s t u d y on the aspects of the B i o l o g y of Tamarindus i n d i c a L was c a r r i e d out from 6 / 7 / 9 0 - 24/12/90, in Z a r i a which is in the Northern Savanna zone of N i g e r i a. Tamarjndus i n d i c a L is an economic t r e e of much v a l u e. Almost a l l i t s p a r t s are u s e f u l . Although i t i s of such economic v a l u e , p u r p o s e f u l propagation of t h e p l a n t in N i g e r i a is not done. A p e r i o d of dormancy is e x h i b i t e d by Tamarind. To r e l e a se t h i s dormancy p e r i o d , v a r i o u s treatments were used, these being mechanical s c a r i f i c a t i o n , c o n c e n t r a t e d s u l f u r i c a c i d , pulp e x t r a c t soaking f o r 5 days, D i s t i l l e d water soaking f o r 5 days, Hot water t r e a t m e n t s at 50°C f o r 30 and 120 m i n u t e s , 70°C f or 30 and 60 m i n u t e s , and 90°C f o r 5 and 10 minutes t i m e exposures. A c o n t r o l of n o n - t r e a t e d seeds was used. Four experiments were conducted to determine the g e r m i n a t i on and e p i c o t y l emergence of the seed and s e e d l i n g s . From t h is t h e speed of g e r m i n a t i o n of 3 d i f f e r e n t seed l o t s was determined along s i d e w i t h the v a r i o u s t r e a t m e n t s . Morphological aspects of the seeds and s e e d l i n g s were also determined. The data were analysed using percentages, means, Analysis of v a r i a n c e (ANOVA) and C o r r e l a t i o n . ANOVA at P = .05, LSD and SSR showed s i g n i f i c a n t d i f f e r e n c e between t r e a t m e n t s and seed l o t s , w i t h no d i f f e r e n c e between r e p l i c a t e s f o r the r e l a t i o n s h i p between t r e a t m e n t s and seed l o t s to g e r m i n a b i l i t y. There was s i g n i f i c a n t d i f f e r e n c e s between t r e a t m e n t s on the day g e r m i n a t i o n was f i r s t n o t i c e d ; w i t h the c o n c e n t r e a t ed s u l f u r i c a c i d treatment having e a r l i e s t g e r m i n a t i o n and also h i g h e r percentages, f o l l o w e d by Mechanical s c a r i f i c a t i o n t r e a t m e n t. Epicotyl emergence was similar to germination. Early germination also resulted to early epicotyl emergence. The earlier the germination and epicotyl emergence, the earlier the seedlings establishment. The vigorous seed lots were determined using a visual vigour rating scale which considered germination, epicotyl emergence speed, number of leaves, and leaflets, stem and root length, and seedlings dry weight with the result showing the C seed lot best followed by A and then B seed lots. Germination in Tamarind is epigeal. No difference between seed lots as regards to number of leaves, within the experimental period existed, but there was for leaflets. The range for the number of leaflets was 6 - 11 pairs. The seedling's paired Eophills were found to be opposite each other with 4 stipules while other leaves alternate and have 2 stipules each.en_US
