Exposure to heat waves and drought improves subsequent leaf heat tolerance for five oak species in southern California

American Journal of Botany, EarlyView.
Abstract Premise Given the threats of climate change, we investigated the impact of high temperatures separately and in combination with reduced soil water on leaf heat tolerance for five oaks (Fagaceae) with overlapping ranges in southern California, USA: Quercus agrifolia and Q. chrysolepis (evergreen species), Q. douglasii and Q.

Index of chlorophyll content in common winter wheat (Tr. aestivum L.) genotypes at grain filling stage

Растениевъдни науки
Chlorophyll content is directly related to the rate of photosynthesis. Changes in the photosynthesis due to reduced amount of chlorophyll affect the weight and quality of grain.

Chlorophyll formation and phytochrome [PDF]

, 1973
The rôle of phytochrome in the regeneration of protochlorophyll (Pchl) in darkness following short exposures to light, as well as in the accumulation of chlorophyll- a (Chl- a ) in continuous light in previously dark-grown seedlings of pea, bean, and ...

Stabilization of PUFA‐Rich Mayonnaise Against Lipid Oxidation: A Review of the Last Three Decades of Research

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Mayonnaise, a widely consumed oil‐in‐water emulsion, is highly susceptible to lipid oxidation due to its high content of polyunsaturated fatty acids (PUFAs) and the presence of pro‐oxidant factors such as low pH and iron from egg yolk. Over the past three decades, extensive research has focused on understanding oxidation mechanisms, analytical

Chemometric Analysis of Chlorophyll a, b and Carotenoid Content in Green Leafy Vegetables

Biologica Nyssana, 2013
Effects of cooking on chlorophyll a and b and total carotenoid content in seven leafy green vegetables (Brussels sprout, white cabbage, kale, chard, garden patience, broccoli and spinach) were evaluated.

Remote sensing of terrestrial chlorophyll content [PDF]

, 2009
Terrestrial chlorophyll content is a key environmental variable that has proved difficult to estimate accurately using remotely sensed data. Some of the pioneering studies in this field were undertaken by Professor Kirill Ya Kondratyev and co-workers in the 1970s and early 1980s.

Optimization of Saponification Process for Quantification of Individual and Total Tocopherols and Phytosterols in Canola Oil Refining By‐Products

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In this study, saponification variables were optimized using a face‐centred central composite design‐response surface methodology. The variables included reaction temperature (50°C–120°C), reaction time (30–180 min), KOH concentration (0.5–3 M) and pyrogallol concentration (0–1% w/v).

Seasonal Fluctuations of Plastochromanol‐8 and α‐Tocopherol Amounts in the Leaves of Cecropia Trees

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Plastochromanol‐8 (PC‐8) is a homologue of γ‐tocotrienol with a longer side chain (eight instead of three isoprene units) and therefore also a representative of the tocochromanol (vitamin E) group. PC‐8 has been determined in various plants and seeds, with Cecropia sp. leaves showing unusually high levels.
