Adaptive Genomic Divergence Across Altitudes in Capsella bursa‐pastoris

Biological Diversity, EarlyView.
Genomic divergence was observed between high‐altitude and low‐altitude populations of Capsella bursa‐pastoris in China, consistent with an important role of ecological factors. Candidate adaptive loci associated with enhanced energy metabolism, photoprotection, and growth plasticity under altitudinal stress were identified.

Evolutionary Agroecology: the potential for cooperative, high density, weed‐suppressing cereals

Evolutionary Applications, 2010
Abstract Evolutionary theory can be applied to improve agricultural yields and/or sustainability, an approach we call Evolutionary Agroecology. The basic idea is that plant breeding is unlikely to improve attributes already favored by millions of years of natural selection, whereas there may be unutilized potential in selecting for ...

Does Stakeholder Pressure Promote Green Innovations and Performance of Agribusiness Companies?

Business Strategy and the Environment, EarlyView.
ABSTRACT The sustainability of agribusiness companies is guided by multiple, sometimes paradoxical, interests. Green innovation is strategic for sustainable development; however, literature shows inconsistencies regarding its impact on environmental and economic‐financial performance.

Investigating the selectivity of weed harrowing with new methods [PDF]

, 2008
In six field experiments it was investigated whether row spacing, timing, direction and orientation of post-emergence weed harrowing in spring barley influenced the selectivity and whether it is important that increasing intensities of harrowing are ...

Comprehensive Characterization of Spelt Wheat and Common Wheat Protein and Viscosity Traits Under Different Field Management Systems

Cereal Chemistry, EarlyView.
ABSTRACT Background There is an increasing interest in healthier, nutrient‐rich foods so alternative grains produced in smaller quantities—including spelt wheat (Triticum spelta L.)—have once again become the focus of consumers. At the same time, the scientific proof of these claims is incomplete.
