Since its introduction, Penncross has set the standard for creeping bentgrass (Agrostis stolonifera L.) cultivars.Recently released cultivars of creeping bentgrass possess improved vegetative characteristics compared with Penncross, but the germination characteristics have not been studied. Germination characteristics such as speed, synchrony, and viability determine the success of newly seeded areas. Traditional establishment from seed involves sowing seed into bare soil or turf that has been treated with non-selective herbicides. In either case, the newly emerging seedlings face little competition from surrounding plants. Although germination characteristics are important when using traditional establishment methods, superior germination characteristics may be necessary when using non-traditional seeding methods such as interseeding. The objectives of this study were to determine differences in germination speed, synchrony, percentage, and weight within and among cultivars of creeping bentgrass, and to investigate the relationship between these germination characteristics and seed weight.
