A new approach for estimating northern peatland gross primary productivity using a satellite-sensor-derived chlorophyll index

open access: yes, 2011
Carbon flux models that are largely driven by remotely sensed data can be used to estimate gross primary productivity (GPP) over large areas, but despite the importance of peatland ecosystems in the global carbon cycle, relatively little attention has ...

PHOTOCHEMICAL RING-OPENING IN meso-CHLORINATED CHLOROPHYLLS [PDF]

open access: yes, 1990
Irradiation of 20-chloro-chlorophylls of the a-type with visible light produces long-wavelength shifted photoproducts, which transform in the dark to linear tetrapyrroles (bile pigments).

Real‐time monitoring of root dielectric properties for assessing crop plant damage caused by foliar application of glyphosate

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise There is a knowledge gap regarding how foliar injury and restricted water uptake can be detected by measuring root dielectric response. This pot study nondestructively evaluated the efficiency of real‐time dielectric measurement to monitor the effects of glyphosate spraying.

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

Rapid assessment of fern spore quality using microscale electrical conductivity testing

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Ex situ spore banks are essential for fern conservation and research, yet traditional germination tests for assessing spore quality are time consuming and labor intensive. We explored whether electrical conductivity (EC), a rapid proxy for seed vigor, could offer an efficient alternative for evaluating fern spore quality. Methods Using

Optimizing Monitoring Programs: A Case Study Based on the OSPAR Eutrophication Assessment for UK Waters

open access: yesFrontiers in Marine Science, 2019
The data and results of the UK second application of the OSPAR Common Procedure (COMP) for eutrophication were used as a case study to develop a generic system (i) to evaluate an observational network from a multi-variable point of view, (ii) to ...

Biochar‐based fertilizers improve nutrient use efficiency in sunflower grown on a subtropical tidal soil

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Improving fertilizer use efficiency is essential for reducing environmental pollution, sustaining agricultural production, and maximizing the economic profitability of crop production systems. This study tested the hypothesis that the formulation strategy of biochar‐based fertilizers, rather than nutrient addition alone, is associated with ...

Three dimensional structure of the light-harvesting chlorophyll a/b protein complex from plant chloroplasts [PDF]

open access: yes, 2002
The light-harvesting chlorophyll a/b protein complex (LHC-II) is the major collector of solar energy in all plants and it binds about half of the chlorophyll in green plants.
