Comparative and Interactive Effects of Reduced Precipitation Frequency and Volume on the Growth and Function of Two Perennial Grassland Species
نویسندگان
چکیده
Premise of research. Water deficits are a common limiting factor of plant growth. Many studies have looked at the effects of drought, but few have compared the independent and interactive effects of multiple dimensions of changing precipitation patterns (e.g., reduced rainfall frequency and reduced rainfall volume) on overall plant growth of individuals with snapshots of growth-related plant performance.

Influence of drought stress on nutritive value of perennial forage legumes
In the next decades, forage legumes are likely to become more important. However, predicted climate change may increase the risk of droughts and thus influence their agricultural performance. Decreases in yield due to water shortage are well documented, while influences on nutritive values are inconsistent. Therefore, we examined the effects of drought on crude protein (CP), neutral deterge...

Turfgrass is one of the important components of ornamental plant in the construction of parks and landscapes so that the purpose of this study was to investigate the influence of type and different concentrations of Copper, Zinc and Cobalt on germination and seedling growth of perennial ryegrass (Lolium perenne L.) and red fescue (Festuca rubra L.) seeds in in vitro conditions. This study was c...
متن کاملPlant Functional Group Composition Modifies the Effects of Precipitation Change on Grassland Ecosystem Function
Temperate grassland ecosystems face a future of precipitation change, which can alter community composition and ecosystem functions through reduced soil moisture and waterlogging. There is evidence that functionally diverse plant communities contain a wider range of water use and resource capture strategies, resulting in greater resistance of ecosystem function to precipitation change. To inves...

Introduction: in addition to pasture grazing, animals are fed on such sources as manual forage, farm straw, etc. Therefore, due to various socio-economic reasons, overgrazing and forage shortage exert adverse effects on rangelands, leading to their degradation. On the other hand, excessive exploitation of rangelands and changes in their use has led to the expansion of invasive species, altering...
متن کاملInteractive effects of elevated CO2 and precipitation change on leaf nitrogen of dominant Stipa L. species
Nitrogen (N) serves as an important mineral element affecting plant productivity and nutritional quality. However, few studies have addressed the interactive effects of elevated CO2 and precipitation change on leaf N of dominant grassland genera such as Stipa L. This has restricted our understanding of the responses of grassland to climate change. We simulated the interactive effects of elevate...
