Animal allure and health linked by plant pigments.
Darwin introduced the idea that ornamental secondary sexual traits have evolved in response to female preferences for showy males. Among such traits, yellow and red carotenoid-based ornaments have been considered as particularly good candidates for explaining why and how females would benefit from mating with showy partners. Because carotenoids can be used for promotion of both health and appea...
متن کاملHyperspectral remote sensing of plant pigments.
The dynamics of pigment concentrations are diagnostic of a range of plant physiological properties and processes. This paper appraises the developing technologies and analytical methods for quantifying pigments non-destructively and repeatedly across a range of spatial scales using hyperspectral remote sensing. Progress in deriving predictive relationships between various characteristics and tr...
متن کاملSeparation of Plant Pigments by Paper Chromatography
Anyone who has ever played on grass or had an unplanned encounter with a bush knows that plants contain pigments which adhere to varying degrees to fabric (and skin!). The fact that a small industry has risen up in aid of attempts to remove stains like these and many others shows that not all of the molecules can be treated in the same way if their removal is desired. Part of the reason behind ...
متن کاملHow Salicylic Acid Modulate Photosynthetic Pigments, Yield and Yield Components of Canola Plant
In this experiment, the possibility of growth promoting of exogenous salicylic acid during two growth stages on chlorophyll content, yield and yield components of canola plant was investigated. For the purpose of improving above traits, salicylic acid was applied in four concentrations (0, 100, 200 and 400 µM) during two different growing stages (first time; when temperature was close to 7-10 °...
متن کاملBiosynthesis of betalains: yellow and violet plant pigments.
Betalains are the yellow and violet pigments that substitute anthocyanins in plants belonging to the order Caryophyllales. These pigments have attracted much attention because of their bioactivities, which range from an antioxidant capacity to the chemoprevention of cancer. However, the biosynthetic pathway of betalains remains under discussion; the main steps have been characterized in recent ...
