Response of Seedling of Festura rubra Varieties to Environmental Conditions1
- L. W. Nittler and
- T. J. Kenny2
Seedlings of red rescue (Festuca rubm L.) varieties and of Chewings rescue (Festuca rubra vat. commutata Gaud.) were grown under controlled conditions in growth chambers. Seedlings differed in growth habit, color of lower leaf sheaths, and green weight. A high correlation was found between decumbent growth habit and green color of lower leaf sheaths. Daily cold periods induced up to 50% of common plants to become decumbent in growth habit. Decumbent plants did not occur if they were grown with continuous warm temperatures. All varieties and seed samples tested with daily cold periods produced mixtures of plants decumbent, intermediate, and upright in growth habit. However, seed samples differed in percentages of these types. Varietal differences were not great enough for precise varietal purity determinations, but some samples of comomn seed could be distinguished from seed of improved varieties.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
