Green leaf volatiles (GLVs) are a class of woundinduced volatile organic compounds emitted by several plant species. Turf grasses emit a complex profile of GLVs upon mowing, as evidenced by the “freshly cut grass” smell, some of which are readily oxidized in the atmosphere to contribute to secondary organic aerosol (SOA). The contribution of lawn-mowing-induced SOA production may be especially ...

abstract turf grass as a main grown cover plant has a unique place in green space planning. in order to study the effect of hydrogel and paclobutrazol on water requirement of turfgrasse (lolium perenne l. barbal) a factorial experiment based on a brcd with 3 replication was conducted in the summer of 2010 in mashhad. the factors under study were 4 levels of hydrogel (0, 3, 6, 9 gr/kg soil), 3 l...

BACKGROUND Numerous injuries have been attributed to playing on artificial turf. Recently, FieldTurf was developed to duplicate the playing characteristics of natural grass. No long-term study has been conducted comparing game-related, high school football injuries between the 2 playing surfaces. HYPOTHESIS High school athletes would not experience any difference in the incidence, causes, and...

Experiments to document the long-term effects of clipping management on N requirements, soil organic carbon (SOC), and soil organic nitrogen (SON) are difficult and costly and therefore few. The CENTURY ecosystem model offers an opportunity to study long-term effects of turfgrass clipping management on biomass production, N requirements, SOC and SON, and N leaching through computer simulation. ...

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...

Kentucky bluegrass can produce quality fairways in the Midwest if it is not mowed too short. Keep track of research. Climates vary widely across the Midwest, complicating the choice of fairway turf grass species. New epidemics of gray leaf spot have weakened the popularity of perennial ryegrass, long a preferred fairway species in many parts of the Midwest. Cultivars are available that accentua...

Little is known about the effects of NaCl stress on perennial ryegrass (Lolium perenne L.) photosynthesis and carbohydrate flux. The objective of this study was to understand the carbohydrate metabolism and identify the gene expression affected by salinity stress. Seventy-four days old seedlings of two perennial ryegrass accessions (salt-sensitive 'PI 538976' and salt-tolerant 'Overdrive') were...
