Fuzhuan brick tea is a dark produced using plant leaves, and its quality strongly affected by Eurotium cristatum. The superior cristatum strain could enhance functional components in tea, improving economic value. To research the lipid-lowering substance of from Anhua country production area, several wild-type strains were screened for lovastatin production. Of all 20 strains, 6 produce lovasta...

The invasion of non-native plants in the Wyoming Basins Ecoregional Assessment (WBEA) area is a major economic and ecological stress, with invasions thought to be hastened by energy developments. Given the potential impacts of nonnative invasive plants and the rapid changes in land use in the WBEA, broad-scale assessments and predictive models of nonnative invasive plant distribution are needed...

BACKGROUND AND AIMS Changes in supplies of resources will modify plant functional traits. However, few experimental studies have addressed the effects of nitrogen and water variations, either singly or in combination, on functional traits. METHODS A 2-year field experiment was conducted to test the effects of nitrogen and water addition on leaf longevity and other functional traits of the two...

Integrating use of seeded perennial cool-season grass pastures with native rangeland can increase available forage and provide a high plane of nutrition for grazing livestock. Our objective was to compare performance of yearling beef heifers grazing native rangeland with those grazing an integrated system that included seeded forages. Twice-replicated, 3-ha pastures seeded to either ‘Rosana’ we...

Crested wheatgrass (Agropyron cristatum (L.) Gaertner.) is a potential source of low-maintenance turf species for use in areas with less water. The main goal of this study was to evaluate turf quality characteristics of 24 crested wheatgrass specimens collected from different locations of Iran as low-maintenance turfgrass. The experimental design was a randomized complete block design with 3 re...
