Striking 20-year grasshopper declines tied to quality of prairie grasses（图）
20-year grasshopper declines tied quality prairie grasses
2020/3/11
A new study shows that grasshopper numbers have declined more than 30% in a Kansas grassland preserve over the past two decades. The results were published in the journal Proceedings of the Natio...
Intact leaf gas exchange provides a robust method for measuring the kinetics of stomatal conductance responses to abscisic acid and other small molecules in Arabidopsis and grasses
Stomatalconductance Kinetics Guardcellphysiology Aquaporin
2019/6/3
Guard cells perceive external and internal stimuli and regulate stomatal conductance in plants. With the use of gas exchange analyzers, time-resolved stomatal conductance responses to light intensity,...
Chemical composition and dry matter digestion of some native and cultivated grasses in Mexico
native grasses chemical composition nutritive value
2015/6/8
The objective of the study was to quantify differences in nutritive value, over four seasons, of native grasses such as Bouteloua curtipendula, Bouteloua trifida, Brachiaria fasciculata, Chloris cilia...
Ruminal degradability of dry matter and neutral detergent fibre of grasses
rumen degradation parameters dry matter neutral detergent fibre in sacco method prediction equations
2015/6/8
A study was conducted (I) to determine rumen degradability (in sacco) of dry matter (DM) and neutral detergent fibre (NDF) of the most important grass species grown in the Czech Republic, (II) to comp...
Determination of indigestible neutral detergent fibre contents of grasses and its prediction from chemical composition
grass indigestible neutral detergent fibre in sacco method
2015/6/5
Five grass species (Dactylis glomerata L., Phleum pratense L., Lolium perenne L., Festuca arundinacea L.) and the hybrid Felina (Lolium multiflorum L. × Festuca arundinacea L.), commonly used in rough...
Effects of grasses on sapling establishment and the role of transplanted saplings on the light environment of pastures: implications for tropical forest restoration
Degradation Light incidence Mexico Rain forest Recovery
2013/11/13
Saplings had high survival (49–88%) regardless of the presence of
grasses. In the presence of grasses, growth of surviving saplings either
increased or was not impacted, and in only one out of eight...
Nutritive Value of Grasses in Semi-arid Rangelands of Ethiopia: Local Experience Based Herbage Preference Evaluation versus Laboratory Analysis
Semi-arid Rangelands Spatial Variation in Feed Quality
2013/5/11
We examined the nutritive value of common grass species in the semi-arid rangelands of Borana in southern Ethiopia using local experience based herbage preference (LEBHP) perception and laboratory tec...
Grassland Response to Herbicides and Seeding of Native Grasses 6 Years Posttreatment
Potentilla recta L. rangeland sulfur cinquefoil wildlife management
2011/7/1
Herbicides are the primary method used to control exotic, invasive plants. This study evaluated restoration efforts applied to grasslands dominated by an invasive plant, sulfur cinquefoil, 6 yr after ...

Research on Fructan in Wheat and Temperate Forage Grasses in Japan
freezing tolerance snow mold resistance
2011/1/1
In autumn, winter wheat and temperate forage grasses, such as orchardgrass, timothy, and perennial ryegrass, accumulate fructan, which is a kind of fructose-based oligo- and polysaccharide. The fructa...
Improving emergence and early seedling growth of two cool season grasses affected by seed priming under saline conditions
Early seedling growth emergence rate seed priming
2010/5/20
Soil salinity threatens initial stages of emergence and early seedling growth in cool season grasses, although it may be tolerant in its adult stages. Today, seed priming has been known as an effectiv...
