Seed size emerged as a governing characteristic for germination parameters and seedling establishment owing to best evolutionary traits of plant which impart major contribution in genetic diversity. Large size increased germination rate and seedling survival, accelerated germination timing, and enhanced seedling growth. Present experiment is carried out to assess the seed size correlates with germination characteristics in Terminalia arjuna. The findings suggest that the seedling vigour is a fixed positive function of seed size needs to be reconsidered. Germination of large seeds recorded slightly higher than small size and ranges from 68.33 to 43.33%. Mean daily germination value ranged between 1.81 to 2.85, Peak value of germination ranged between 3.15 to 4.59, Germination value ranged between 5.79to 13.67 and germination speed ranged between3.71 to 5.88. The existence of conflicting selection might explain the occurrence of an optimal seed size in some plant species without invoking a seed number-size trade-off. Hence, it is recommended to use only medium and large size seeds for growing, because they do result in higher germination behavior and seedling establishment.
