Seedling Difference Among Agrostis Species and Varieties1

L. W. Nittler and T. J. Kenny2

Seedlings of four Agrostis species, two represented by two varieties each, were grown with continuous light and supplied with a complete nutrient solution. Within 5 weeks significant differences developed among species in several characteristics. A. alba L. plants had large leaves and stems, whereas those of A. canina L. were small in leaf size and stem diameter. A. palustris Huds. and A. tenuis Sibth. were intermediate in leaf size and stem diameter, but differed from each other in stem length and growth habit. A. alba and A. tenuis were upright in growth habit, but most plants of A. canina and A. palustris were decumbent. Plants could be classified easily as to species. Significant differences were not found between the varieties of A. palustris, ‘Penncross’ and ‘Seaside,’ but varieties of A. tenuis, ‘Exeter’ and ‘Highland,’ differed in several characteristics.

Key Words: Bentgrass • Red top • Growth chamber • Nutrient solution • Temperature • Anthocyanin
