The Physiology of Seed Germination in Groundnut (Arachis hypogaea L) Cultivar GG-2. I. Effect of Seed Size

The seeds of groundnut cultivar GG-2 were categorized according to their test weight (100 seed weight) as bold (58.2 g), medium (37.9 g), small (24.9 g), small wrinkled (13.4 g) and control (30.3 g) seed lot. The variation in their size and dimension was also taken into account. The overall germination percentage was high for medium size seeds and was closely followed by bold seeds. The performance of the small and small wrinkled seeds was comparable to that of control. The seed vigour was found to be higher with heavier seeds. Small seeds exhibited equally good performance in response to seed germination and growth of the seedling components. There were no significant differences for the development of hypocotyl, epicotyl and plumule.
