Effects of sulphuric acid and hot water treatments on seed germination of tamarind (Tamarindus indica L)

Abstract

A study was carried out to investigate the effects of sulphuric acid and hot water treatments on the 
germination of Tamarind ( Tamarindus indica L). Seeds were placed on moistened filter papers in 28 
cm diameter Petri dishes under laboratory condition for germination. 330 seeds of T. indica (10 seeds 
per Petri dish) with three replicates each were used. The highest germination was recorded in seeds 
treated with 50 per cent sulphuric acid concentration with 60 min soaking period. Germination was 
observed to be enhanced by increase in the sulphuric acid concentration, water temperature, and 
soaking period in all the trials, except with absolute sulphuric acid where poor response was 
observed. Results of this study may serve as useful information in the production and improvement 
of the tree species, as knowledge on seed germination requirements is a critical factor in seedlings 
production.
