Abstract

Background

Tamarindus indica is an indigenous legume, which has been recognised as a potential nitrogen fixing tree in the semi-arid region of Nigeria (Okoro et al., 1986). T. indica is a leguminous tree in the family fabaceae native to tropical Africa. The genus is a monotypic taxon, having only a single species. It is cultivated widely in India, Bahamas, West Indies, and USA among others. The species is a slow-growing one; long lived massive tree reaches under favourable condition a height of 12–24 m and a trunk circumference of 7.5 m. The bright green, fine feathery foliage is composed of pinnate leaves, each having 10–15 pairs of oblong leaflets 1.25–2.5 cm long and 5-6 mm wide which fold at night (Okoro et al., 1986).
Tamarind (Tamarinds indica L) belongs to the family Leguminoseae (Khanzada et al., 2008). It is an evergreen tree that is native to tropical and subtropical regions of Africa and South Asia (Doughari, 2006).

Methods

The seed of theThese fruits were soaked in water for overnight. The fleshy fruits was removed and the seeds were extracted and air dried for more than 6 hrs. The damage seeds were sorted from the good ones and discarded. Some seeds are bigger in size than the other ones. Those bigger ones were sorted from the small ones. The big seeds was tagged “large size seeds”, the semi-big ones will be tagged “medium size seeds” and the smallest seeds was be tagged “small size seeds”. All experiments was conducted at the botany laboratory Kaduna State University under laboratory conditions. Preliminary Germination Tests:
Germination was carried out on freshly harvested seeds using some randomly selected ones according to the methods of (Etejere and Ajibola 1980, Agboola 1996, 1998). About 100 seeds were surface sterilized with 0.1% mercuric chloride solution for 30s and rinsed in several changes of distilled water. The process continued.

Results

Mean squares for varying concentrations of sulphuric acid on germination of Tamarindus indica
Source of variation df DG PG PH RL VG *- Significant (P≤0.05), **- Significant (P≤0.01), df- degree of freedom, DG- days to germination, PG- percent germination, PH- plant height, RL- root length, VG- vigour, NL- number of leaves
The result showed the Effect of varying concentrations of Sulphuric acid on germination of Tamarindus indica
Treatment DG PG PH RL VG Means with the same letter within a column are not significantly different at P≥0.05 according to Duncan Multiple Range Test (DMRT), DG- days to germination, PG- percent germination, PH- plant height, RL- root length, VG- vigour, NL- number of leaves

Conclusions

The result of the present finding can be use in providing for standardization of this plants in Agricultural, ethno medicine as well as chemotherapy in authentication and level of adulteration.
