Advancements in light-emitting diode (LED) technology have made them a viable alternative to current lighting systems for both sole and supplemental lighting requirements. Understanding how wavelength specific LED lighting can affect plants is thus an area of great interest. Much research is available on the wavelength specific responses of leaves from multiple crops when exposed to long-term w...

BACKGROUND In a semi-arid ecosystem, water is one of the most important factors that affect vegetation dynamics, such as shrub plantation. A water use strategy, including the main water source that a plant species utilizes and water use efficiency (WUE), plays an important role in plant survival and growth. The water use strategy of a shrub is one of the key factors in the evaluation of stabili...

How species respond to environmental variation can have important consequences for population and community dynamics. Temperature, in particular, is one source of variation expected to strongly influence plant performance. Here, we compared photosynthetic responses to temperature across a guild of winter annual plants. Previous work in this system identified a trade-off between relative growth ...

BACKGROUND AND AIMS During the Mesozoic, the polar regions supported coniferous forests that experienced warm climates, a CO(2)-rich atmosphere and extreme seasonal variations in daylight. How the interaction between the last two factors might have influenced water use of these conifers was investigated. An experimental approach was used to test the following hypotheses: (1) the expected benefi...

To meet the challenge of a limited and costly water supply, South African sugarcane growers will have to find ways of increasing the efficiency of irrigation to maintain high cane and sucrose yields. The term ‘water use efficiency’ (WUE) is generally used as a measure of the overall effectiveness of water (either rainfall or irrigation, or both) for crop production. WUE can be defined as cane y...

Trade-offs are central to many topics in biology, from the evolution of life histories to ecological mechanisms of species coexistence. Trade-offs observed among species may reflect pervasive constraints on phenotypes that are achievable given biophysical and resource limitations. If so, then among-species trade-offs should be consistent with trade-offs within species. Alternatively, trait vari...

Improving winter wheat grain yield and water use efficiency (WUE) with minimum irrigation is very important for ensuring agricultural and ecological sustainability in the Northern China Plain (NCP). A three-year field experiment was conducted to determine how single irrigation can improve grain yield and WUE by manipulating the "sink-source" relationships. To achieve this, no-irrigation after s...

We discuss the complete virtual and soft-photonic O(α) corrections to γγ → WW within the electroweak Standard Model for arbitrary polarized photons. In the on-shell renormalization scheme for fixed MW no leading corrections associated with the running of α or heavy top-quark and Higgs-boson masses occur. The corrections turn out to be of the order of 10%, but can become much larger where the lo...

BACKGROUND AND AIMS Stomata play an important role in both the CO(2) assimilation and water relations of trees. Therefore, stomatal traits have been suggested as criteria for selection of clones or genotypes which are more productive and have larger water-use efficiency (WUE) than others. However, the relationships between plant growth, WUE and stomatal traits are still unclear depending on pla...
