CER and leaf characteristics of four tall fescue (Festuca arundinacea Schreb.) selections differing in forage yield

Creator:: Cohen, Cynthia Joy
Abstract:: Gas exchange, leaf area development, leaf anatomy and stomatal characteristics of four tall fescue selections differing in forage yield were examined to provide further insight into characteristics associated with yield differences of these selections. Winter-growing TFM 26 and TFM 16, the highest and lowest-yielding selections, respectively, and summer-growing selections TFK...

Meiotic chromosome behavior in two tall fescue (Festuca arundinacea Schreb.) genotypes and their sterile hybrid

Creator:: Vásquez, Raul Moreno
Abstract:: Two diverse genotypes of tall fescue, Festuca arundinacea Schreb (6X=42), with normal fertility, produced upon intercrossing, vigorous F ₁ hybrid plants that were sterile. One parent genotype (P₁) was from P. I. 234-906, introduced from Switzerland and the other (P₉) was an introduction from Turkey, P. I. 174-209. P₁ and...

Heritability for perloline, nitrogen, and digestibility characteristics in tall fescue (Festuca arundinacea, Schreb.) single-crosses grown in two locations

Creator:: Watson, Clarence Ellis
Abstract:: Tall fescue often results in poor liveweight gains. This may be accounted for by variations in perloline content, nitrogen content, or digestibility of the plant. Two groups of tall fescue plants were examined for each of these traits. These groups consisted of (a) fifteen single-crosses of a six parent diallel...

Physiological and biochemical characteristics of two cultivars of tall fescue (Festuca arundinacea Schreb.) under different environmental conditions

Creator:: Fino, Antonio Carlos
Abstract:: Two cultivars of tall fescue (Festuca arundinacea Schreb.) with contrasting growth habits were studied under field and growth chamber conditions. Fawn, an established cultivar since 1964, and TFM, an experimental line, were observed to grow better during spring and fall months respectively, in the field. Different temperature regimes of 10/4,...

Response of Canada milkvetch (Astragalus canadensis var. mortonii (Nutt.) Wats.) to range and forest improvement practices in Northeastern Oregon

Creator:: Wood, Benjamin William
Abstract:: The response of Canada milkvetch (Astragalus canadensis var. mortonii) to range and forest improvement practices was studied on a stand of mixed-coniferous forest which was clear -cut and burned in 1963 and 1964, respectively. The field studies were conducted on the Hall Ranch of the Eastern Oregon Experiment Station during...

Techniques and media for excised tip culture of Vinifera cultivars

Creator:: Subhanij, Thiravira
Abstract:: Excised apical stem tips (2-5 mm) of grape cultivars grew well on Murashige and Skoog's (1962) medium for tobacco callus. Additions of glycine were not essential but gave a slight stimulus to growth. Naphthalene acetic acid slightly reduced growth rates but reductions were not statistically significant. Kinetin and coconut milk...
