Photosynthesis and PSII functionality of drought-resistant and drought-sensitive weeping lovegrass plants

Environmental and Experimental Botany, 2003
Abstract World areas subject to drought are expected to increase under conditions of climate change. The purpose of this study is to clarify the response of grass species that can grow and produce under water stress. Therefore leaf photosynthesis, chlorophyll fluorescence and pigment content response to water stress were studied in two varieties of ...

Invasion of weeping lovegrass reduces native food and habitat resource of Eusphingonotus japonicus (Saussure)

Biological Invasions, 2010
To examine the relative importance and interactions of trophic and non-trophic effects of plant invasions on herbivores, we investigated how the invasion of weeping lovegrass Eragrostis curvula impacted Eusphingonotus japonicus, a food generalist grasshopper endemic to gravelly floodplains with sparse vegetation in Japan.

Registration of Catalina Weeping Lovegrass¹ (Reg. No. 24)

Crop Science, 1971
’CATALINA’ weeping lovegrass, Eragrostis curvula (Schrad.) Nees, was developed by the Plant Science Research Division, Agricultural Research Service, U. S. Department of Agriculture, and tested and released cooperatively with the Arizona Agricultural Experiment Station, and Plant Sciences Division, Soil Conservation Service, U. S.

Ultrastructural interactions of one strain of Magnaporthe grisea with goosegrass and weeping lovegrass

Canadian Journal of Botany, 1992
In leaves of the susceptible host, weeping lovegrass, strain 4091-5-8 of the rice blast fungus, Magnaporthe grisea, elicited no ultrastructurally detectable responses of underlying epidermal cells during appressorium development or penetration peg formation.

Interactions of two strains of Magnaporthe grisea with rice, goosegrass, and weeping lovegrass

Canadian Journal of Botany, 1990
Two strains of the fungus Magnaporthe grisea caused responses in goosegrass, weeping lovegrass, and rice that varied from no visible symptoms, through isolated discrete lesions with or without brown margins, to coalescing lesions that completely killed the inoculated areas of the leaf.

Observational aspects on a dominant spectral frequency in an airflow over a weeping-lovegrass stand

Boundary-Layer Meteorology, 1986
Mean and fluctuating wind velocities were measured above a flexible stand (weeping-lovegrass). A waving phenomenon ‘Honami’ appeared over the stand during the observation period. Some spectral parameters were derived from the vertical wind fluctuations. A dependency of frequency on mean horizontal wind velocity was found.

Differential Tolerance of Weeping Lovegrass Genotypes to Acid Coal Mine Spoils¹

Agronomy Journal, 1980
AbstractPlant genotypes having greater tolerance to mineral stress are needed for use on problem soils. Two examples of such stress are mineral element toxicity (excess Al, Mn, etc.) in strongly acid soils and mine spoils, and Fe‐related chlorosis in certain calcareous soils.

Breeding Apomictic Lovegrasses: Forage Potential of Boer ✕ Weeping Hybrids¹

Crop Science, 1984
Breeding schemes have been developed for several apomictic species. However, few assessments of the potential of hybrids developed through manipulation of apomixis have been published. Apomictic lovegrass Eragrostis curvula (Schrad.) Nees, hybrids were developed from crosses of sexual boer ✕ apomictic weeping lovegrass.

Genome polymorphisms and gene differential expression in a ‘back-and-forth’ ploidy-altered series of weeping lovegrass (Eragrostis curvula)

Journal of Plant Physiology, 2007
Molecular markers were used to analyze the genomic structure of an euploid series of Eragrostis curvula, obtained after a tetraploid dihaploidization procedure followed by chromosome re-doubling with colchicine. Considerable levels of genome polymorphisms were detected between lines.

Induced Seed Dormancy in Weeping Lovegrass, Eragrostis curvula¹

Crop Science, 1973
Induction of dormancy in seeds of weeping lovegrass, Eragrostis curvula (Schrad.) Nees, by cool temperatures imposed during imbibition was first observed during germination trials of several warm‐season grasses. The purpose of the work reported here was to define the conditions necessary for the induction of this dormancy.
