Today these tests are one of the most successful tests for seed vigor and have a good correlation to field emergence (TeKrony et al., 1989). Gutierrez et al. (1993) by working on seed deterioration of different corn genotypes observed that seed viability, vigour, and percent of emerged seed sand decreased mainly with increasing in deterioration levels. Decrease in seed vigour as affected by deterioration was proven in mungbean (Bishnoi and Santose, 1996) and chickpea seeds (Dahiya et al., 1997).
