Seasonal trends in separability of leaf reflectance spectra for Ailanthus altissima and four other tree species
… May 13 through August 24, 2008, and spectral reflectance factor measurements were gathered for each tree using an ASD (Boulder, Colorado) FieldSpec Pro full-range spectroradiometer. The original data covered the range from 350-2500 nm, with one reflectance measurement collected per one nm …

Using Leaf Spectra to Elucidate the Taxonomy and Ecology of Living and Dried Plants
… and management of nature. The shortwave spectral reflectance of leaves is a promising tool for rapidly identifying species at different taxonomic ranks and predicting important plant functional traits. However, the spectral reflectance of leaves changes in response to biotic and abiotic …

High throughput phenotyping and quantitative genetics of leaf functional traits in C4 grasses
… phenotyping (HTP) methods for measuring leaf functional traits need to be evaluated beyond proof-of-concept studies. Chapter 2 and Chapter 3 aimed to understand the scope in which statistical models developed from hyperspectral reflectance measurements could be applied to predict key leaf …

High-throughput phenotyping and genetic mapping of photosynthetic traits and ozone responses in maize and soybean
… a high-throughput method to map photosynthetic leaf-level traits in soybean. Most studies of plant responses to elevated O3 have occurred in C3 plant species. The goal of Chapter 2 was to improve understanding of the O3 response in maize. B73 and Mo17, two of the advanced public lines …

Estrategias agronómicas para afrontar la escasez hídrica e incrementar la sostenibilidad del mandarino en condiciones semiáridas
… A new indicator, denoted as VIRI, based on leaf reflectance with similar sensitivity to ΨS and soil water content was also developed, and it was found that wavelengths in the shortwave infrared region between 1540 and 1740 nm allow differentiation among trees without water limitations and …
