Effect of drought stress on yield, proline and chlorophyll contents in three chickpea cultivars [PDF]

open access: yes, 2010
Drought stress is one of the major abiotic stresses in agriculture worldwide. This study was carried out to investigate the effect of drought stress on proline content, chlorophyll content, photosynthesis and transpiration, stomatal conductance and yield

Success of coastal sage scrub restoration is influenced by local adaptations of shrub species

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Restoring plant communities is increasingly challenging with climate change. While practitioners have traditionally used local seed sources, many are recommending assisted migration, possibly from more extreme environments such as inland rather than coastal environments, for restoration.

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

open access: yesAmerican 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.

Characteristics of deep chlorophyll maximum in the Northeastern Mediterranean with respect to environmental conditions

open access: yes, 1996
The vertical distribution of chlorophyll-a was recorded throughout the northern part of the Levantine Basin of the eastern Mediterranean and was related to patterns of the physical dynamics for October 1991-March 1994 period.

A well‐resolved phylogeny of Cuscuta subgenus Monogynella based on data drawn from all three plant genomes

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Cuscuta (dodders) consists of ~200 species circumscribed into four subgenera (Monogynella, Cuscuta, Pachystigma, and Grammica) and is the only parasitic genus in Convolvulaceae (the morning‐glory family). This group shows a significant diversity in plastid functionality and represents a rare mixotrophic system among parasitic plants ...

Liquid–Liquid Equilibrium Data for Refined Olive Pomace Oil + Oleic Acid + Ethanol + Water Systems: Application to Solvent Deacidification

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT This study presents the first experimental liquid–liquid equilibrium (LLE) data for quaternary systems composed of refined olive pomace oil, oleic acid, ethanol, and water at 303.15 K. These data are essential for the design and optimization of solvent‐based deacidification processes, particularly for oils with high free fatty acid (FFA ...

Monitoring of Plant Chlorophyll and Nitrogen Status Using the Airborne Imaging Spectrometer AVIS [PDF]

open access: yes, 2002
Airborne hyperspectral remote sensing enables not only spatial monitoring of vegetation cover, but also the derivation of individual plant constituents such as chlorophyll and nitrogen content.

Chlorophyll-a concentrations in phytoplankton fractions in waters of the Black Sea

open access: yes, 1984
Comparison of daily and diel variability of chlorophyll-a concentration at three long-term stations in meso- and eutrophic regions indicates that their values are similar.
