Adequacy of pre-germinative treatment for seed Tamarindus indica L

The objective of this work was to test the methods for overcoming dormancy, as well as to identify the best time for immersion of tamarind seeds in concentrated sulfuric acid. The maximum potential for emergence is obtained by immersion in concentrated sulfuric acid for 30 minutes or cuts in the integuments. To obtain more vigorous seedlings the immersion method in concentrated sulfuric acid for 30 minutes is the most efficient. The immersion time of tamarind seeds in sulfuric acid should be 36.6 minutes for the greatest emergence and vigor.
