Coordination of physiological and morphological acclimation of shade-grown tree saplings to late-season canopy gap formation
… them to a naturally occurring canopy gap after leaf development was completed in the shade. A series of experiments with the same basic experimental design was conducted on up to four species of temperate deciduous hardwoods: red oak (Quercus rubra L.), sugar maple (Acer saccharum Marsh.), tulip …

High throughput phenotyping and quantitative genetics of leaf functional traits in C4 grasses
… Phenotyping complex traits such as water and nitrogen use efficiency in genetically diverse populations is currently a bottleneck in crop improvement because it is time and labor intensive. To harness the diversity available to improve crop productivity, high throughput phenotyping (HTP) …

Effect of Population Sources and Species Pools on Community Phylogenetic and Functional Diversity During Restoration
… had higher functional trait values (especially leaf area and leaf nitrogen content) in comparison to when established with local ecotype sources of the dominant species. In addition, the functional relatedness among subordinate species established with local ecotypes was less (more functionally …

Water Requirements, Use Efficiency, and Insect Infestation in Brussels Sprouts, and Nitrogen Use Efficiency in Sweet Basil under Low Tunnels compared to Open-field Production
… their relationship with water use efficiency, nitrogen use efficiency, and the level of protection against insect injury. Low tunnels increased yield, number of sprouts, and water use efficiency of Brussels sprout production. In addition, LTs decreased irrigation requirements, irrigation …

Influencia del uso de cubiertas vegetales sobre la fertilidad del suelo, la expresión vegetativa de la vid y la composición de la uva y del vino en un viñedo de Tempranillo (Vitis vinifera L.) de la D.O.C. Rioja
… its pH was basic and the organic matter content was low (< 1 %), texture was loamy for the topsoil and sandy loam in deeper horizons. Results showed differences in soil moisture between treatments for short periods of time from July until the end of August, especially in the clover cover …
