Effect of various pre-treatments on the seedling growth performance of Tamarindus indica L.

ABSTRACT

Pre-treatment of seeds of Tamarindus indica L. with 95% sulphuric acid for 5, 10 or 15 min, methanol, ethanol, iso-propanol or butanol for 10 or 20 min, or boiling water for 10, 15, 20 or 30 min, was used to determine the effect of the various treatments on the development and vigour of the resultant seedlings.
