Photosynthetic pigment composition has been a major study target in plant ecophysiology
during the last three decades. Although more than 2000 papers have been published, a …

This study explored reflectance indices sampled with a 'leaf reflectometer'as measures of
pigment content for leaves of contrasting light history, developmental stage and functional …

Leaf pigment content can provide valuable insight into the physiological performance of
leaves. Measurement of spectral reflectance provides a fast, nondestructive method for …

Established reflectance-based approaches for estimation of foliar pigment contents assume
close relationship between leaf absorbance and reflectance. Complex organization and …

The physiological reason that higher plants are green is unknown. Other photosynthetic
organisms utilize pigments that strongly absorb green light; therefore, there must have been …

Photosynthetic pigments are an integral and vital part of all photosynthetic machinery and
are present in different types and abundances throughout the photosynthetic apparatus …

This study examined the ability of the Photochemical Reflectance Index (PRI) to track
seasonal variations in carotenoid pigments and photosynthetic activity of mature evergreen …

Optical leaf profiles depend on foliar pigment type and content, as well as anatomical
aspects and cellular ultrastructure, whose effects are shown in several species …

Background Colour is a consequence of the optical properties of an object and the visual
system of the animal perceiving it. Colour is produced through chemical and structural …

Leaf pigment content and spectral reflectance were examined in four conifer species from
the Pacific Northwest and Canadian boreal forest. Our goal was to evaluate the causes of …
