(Texas A&M University. Libraries, 1977)A taxonomic study was made of two genera, Dichanthelium and Panicum, in order to justify the elevation of Dichanthelium to generic rank. A comparison of all published characters, all new character differences found by the ...
-
(Texas A&M University. Libraries, 1979)A biosystematics treatment was made of the grass genus Eriochloa in North America. This revision recognized the following 19 taxa: E. acuminate var acuminate, E. acuminate var. minor, E. aristata var. aristata, E. aristata ...
-
(Texas A&M University. Libraries, 1985)A biosystematic treatment was made of the New World genus Erioneuron. Materials for morphological, electrophoretic, anatomical, and cytological studies were collected from naturally occurring populations, and from herbarium ...
-
(Texas A&M University. Libraries, 1985)A biosystematic treatment was made of the Muhlenbergia repens complex. Materials for morphological, anatomical, embryological, and cytological studies were collected from throughout the geographic region of this complex. ...
-
(Texas A&M University. Libraries, 1989)Population samples of Schizachyrium scoparium, collected from Texas (vars. divergens, frequens, littorals, and virile) and New Mexico (var. neomexicanum), and herbarium specimens (including type specimens of Andropogon ...
-
(Texas A&M University. Libraries, 1977)Incubation experiments were conducted for 40 days at 28+-1*C to determine the effect of Hg and As in leaf, stem, and root tissues of common bermudagrass added to a Norwood silt loam and a Houston Black clay on microbial ...
-
(Texas A&M University. Libraries, 1986)Two separate investigations were conducted to study the influence of intraspecific competition and herbivory on plant and tiller demography of the bunchgrass Schizachyrium scoparium. The investigations were conducted over ...
-
(Texas A&M University. Libraries, 1980)The most generally limiting nutrient to growth of forage grasses is fixed nitrogen in the form of No3- or NH4+. Dinitrogen fixation by bacteria associated with forage grass roots in a system which would provide plants with ...
-
(Texas A&M University. Libraries, 1982)Texas wintergrass (Stipa leucotricha Trin. & Rupr.) is an erect, tufted, cool-season, perennial which is an important component in plant communities of central and northcentral Texas. Experiments were conducted in the ...
-
(Texas A&M University. Libraries, 1979)Gulf cordgrass occupied intermediate elevations between hydric species at lower elevations and more mesic species at high elevations on the Welder Wildlife Refuge. Botanical composition shifted apparently because of season ...
-
(Texas A&M University. Libraries, 1980)Seventy-seven genotypes of buffelgrass were screened for resistance to the spittlebug complex A. albofasciata (Lallemand) and. P. simulans (Walker) in Apodaca, N. L. Screening involved artificially infesting plants in caged ...
-
(Texas A&M University. Libraries, 1983)Eighteen half-sib families of kleingrass, Panicum coloratum L., were evaluated in each of three environmental periods (May, July, and September) in 1982. These families were evaluated within each period for tiller height, ...
-
(Texas A&M University. Libraries, 1986)The impact of herbivory (cattle) on dynamics of plant parts of individual tillers of little bluestem (Schizachyrium scoparium) and brownseed paspalum (Paspalum plicatulum) were studied in a simulated short-duration grazing ...
-
(Texas A&M University. Libraries, 1977)The distribution and metabolism of 14C-1- From a nursery of 200 grass introductions six accessions were chosen for evaluation of forage and seed yield and quality in response to management practices. Species represented ...
-
(Texas A&M University. Libraries, 1989)The response of kleingrass standing crop, tissue fluxes and tiller dynamics, and the response of livestock gains and intake to early-season grazing treatments were investigated a t McGregor, Texas. The study evaluated the ...
-
(Texas A&M University. Libraries, 1994)Eleven Pennisetum orientale L. C. Rich. accessions from different geographical regions were studied at College Station, Texas for chromosome number, morphology, method of reproduction, and fertility. Differences were ...
-
(Texas A&M University. Libraries, 1977)Low temperature discoloration of warm season turfgrasses occurs with the advent of cool fall temperatures above 0 C but below 10 to 12 C. Total loss of the pigment system and subsequent death of the leaves and stems of the ...
-
(Texas A&M University. Libraries, 1993)Changes in the red:far-red ratio (R:FR) of solar radiation are an important environmental signal influencing dicotyledonous plant development. Recent studies conducted mainly in controlled environments also indicate that ...
-
(Texas A&M University. Libraries, 1980)Three warm-season grass species were grown to evaluate relationships between forage quality and environmental conditions. Two selections of kleingrass (Panicum coloratum L.), Kleingrass 75 and Kleingrass 75-25, green ...
-
(Texas A&M University. Libraries, 1986)Introducing low-maintenance, perennial, plant species into grass pastures by sod-seeding has been identified as a method for improving forage quality and quantity with fewer cultural inputs, and for providing other plant ...
