Shade and Traffic Tolerance of Bermudagrass and Zoysiagrass
Shade and traffic can reduce turfgrass coverage and playability on both golf courses and sports fields. Five cultivars of bermudagrass and seven cultivars of zoysiagrass were planted in the summer of 2007 and maintained under typical golf course fairway and sports field conditions. Plots were shaded continuously beginning spring 2008 with a 50% light reducing fabric. A second study was implemen...
متن کاملTree cover at fine and coarse spatial grains interacts with shade tolerance to shape plant species distributions across the Alps.
The role of competition for light among plants has long been recognised at local scales, but its importance for plant species distributions at larger spatial scales has generally been ignored. Tree cover modifies the local abiotic conditions below the canopy, notably by reducing light availability, and thus, also the performance of species that are not adapted to low-light conditions. However, ...
متن کاملTolerance of soil pathogens co-varies with shade tolerance across species of tropical tree seedlings.
A negative feedback between local abundance and natural enemies could contribute to maintaining tree species diversity by constraining population growth of common species. Soil pathogens could be an important mechanism of such noncompetitive distance and density-dependent (NCDD) mortality, but susceptibility to local pathogens may be ameliorated by a life history strategy that favors survivorsh...
متن کاملShade tolerance plasticity in response to neutral vs green shade cues in Polygonum species of contrasting ecological breadth.
Here we examined species differences in perception and response to two distinct types of shade cue, reduced photosynthetically active radiation (PAR) with and without reduced red : far red ratio (R : FR), in Polygonum persicaria and Polygonum hydropiper, two closely related annuals of contrasting ecological breadth. We compared plasticity data for light-gathering traits from glasshouse experime...
متن کاملHerbivory on Temperate Rainforest Seedlings in Sun and Shade: Resistance, Tolerance and Habitat Distribution
Differential herbivory and/or differential plant resistance or tolerance in sun and shade environments may influence plant distribution along the light gradient. Embothrium coccineum is one of the few light-demanding tree species in the temperate rainforest of southern South America, and seedlings are frequently attacked by insects and snails. Herbivory may contribute to the exclusion of E. coc...
