If breeders can increase their imported genetic materials by 10 percent, the marginal cost of wheat variety production will fall by 2.2 percent .Such an effect, a type of spillin, has long been known to play an important role in the effectiveness of spending on agricultural research . Our study demonstrates that spillins are also an …

The systems approach has several important implications for second generation models
While there was a sense that “decision support” was important, the model developments nevertheless began with research tools that were motivated primarily to better understand basic processes and effects on system performance. As long as model development is motivated primarily by academic and research outcomes, it will remain only loosely connected to user needs. Therefore, …
Light and carbon availability follows a diurnal cycle creating different signaling inputs
Under sustained low-temperature stress, tissue acclimation fails, leading to exhaustion and the onset of severe PCI. Preharvest factors, including genotype, environmental variables, and agronomic practices, all interact to influence PCI severity. PCI is more severe in tissues harvested before reaching horticultural maturity , as the developmental pathways are incomplete and will be largely disrupted by …
