The MERIS Terrestrial Chlorophyll Index (MTCI) is designed to monitor vegetation condition via an estimation of chlorophyll content. Its simplicity of calculation, suitability for automation and most importantly, sensitivity to all and notably, high values of chlorophyll content made it a suitable level-2 ESA product. This index effectively combines information on leaf area index and the chloro...

High-throughput, noninvasive field phenotyping has revealed genetic variation in crop morphological, developmental, and agronomic traits, but rapid measurements of the underlying physiological and biochemical traits are needed to fully understand genetic variation in plant-environment interactions. This study tested the application of leaf hyperspectral reflectance (λ = 500-2,400 nm) as a high-...

Plantlets grown in conventional tissue culture systems usually encounter physiological and anatomical abnormalities including inability to photosynthesize, low chlorophyll content, open stomata, lack of a cuticle layer in the leaf, abnormal xylem parenchyma etc. Photoautotrophic and photomixotrophic systems could diminish these problems. The purpose of this study was to increase the chlorophyll...

Soil salinity is an increasingly serious problem worldwide that reduces agricultural output potential. Selected beneficial soil bacteria can promote plant growth and augment tolerance to biotic and abiotic stresses. Bacillus subtilis strain GB03 has been shown to confer growth promotion and abiotic stress tolerance in the model plant Arabidopsis thaliana. Here we examined the effect of this ben...

Vegetation phenology, as used and studied the related studies, refers to the relationship between climate and periodic development of photosynthetic biomass. selected 15 Hornbeam plots (Carpinus betulus) from study area in a mountainous region from 520m to 1310m above sea level. Ground observations of hornbeam tree growth process from January to December 2004 in 15 day intervals were performed ...

ABSTRACT. Net photosynthesis, dark respiration, chlorophyll and carbohydrate content, and leaf and shoot growth in plants of evergreen olive (Olea europaea L.) grown under controlled conditions were measured to assess changes in carbon balance during leaf development of the 6th, 12th, and 16th node (from the base, first flush) through expansion to maturity. Shoot and leaves expanded in a sigmoi...

Fresh-cut leafy vegetables have been gaining importance in the human diet both for their nutraceutical proprieties and low calories content. The preparation procedures for fresh-cut production and the storage system may lead to severe leaf damages that may affect leaf colour and induce shortened shelf life. The aim of this work was to study the leaf pigment changes in cut and whole Swiss chard ...

Phytochrome is thought to control the induction of leaf senescence directly, however, the signalling and molecular mechanisms remain unclear. In the present study, an ecophysiological approach was used to establish a functional connection between phytochrome signalling and the physiological processes underlying the induction of leaf senescence in response to shade. With shade it is important to...
