ABSTRACT
Seed is the important stage of a plant but biology of the seeds is usually ignored. Seed characteristics depict the sum total effect of various stresses and strains. Viable seed is one which is capable of germinating under the proper circumstances. For the quick test of viability of seeds, tertrazolium (TTZ) is an excellent indicator of reduction in biological materials. On the basis of tetrazolium chloride staining pattern seed vigour classes of A. catechu were also made.
