) indicated that morphological variation in tall fescue germplasm was heritable, and that several traits including plant height and dry matter yield had a high narrow sense heritability value. Morphological traits are of great importance in selecting rational

uniform across planting dates. Planting dates separated by 3 weeks in Wisconsin had no effect on plant height, but did influence days to silking and yield components of crosses of several open-pollinated sweet corn cultivars ( Revilla and Tracy, 1997

Red firespike is a vigorous ornamental shrub growing to ≈6 ft in height. It has an upright growth habit and is commonly cultivated as an ornamental plant in the garden due to its attractive tubular red flowers ( Daniel, 1995 ). The plant has

Controlling plant stem elongation is common in ornamental plant production. Height control is necessary to meet industry standards for target plant height ( Fisher and Heins, 1995 ), to increase plant aesthetics by producing more compact plants
