摘要: Abstract We conducted a greenhouse study to examine the effects of different habitat conditions and environmental resources on growth rates crimson fountaingrass, an invasive, alien, perennial grass in South Africa. To help understand factors promoting spread this emergent alien grass, we investigated temperature regimes, nutrient moisture addition, soil type seedling biomass allocation. Our results suggest that fountaingrass seedlings do not tolerate drought because they died within 1 mo without water. Additional nutrients extra water increased throughout period. Higher temperatures with development belowground This demonstrates importance available their interaction some growth. ...
