Evaluating the performance of xanthophyll, chlorophyll and structure-sensitive spectral indices to detect water stress in five fruit tree species por Ballester, Carlos, Zarco-Tejada, Pablo J., Nicolás, Emilio, Alarcón, Juan J., Fereres, E., Intrigliolo, Diego S., Gonzalez-Dugo, V.

“…Multi-spectral and thermal images were acquired from an unmanned aerial system while concomitant measurements of stomatal conductance (g(s)), stem water potential (psi(s)) and photosynthesis were taken. The Normalized Difference Vegetation Index (NDVI), red-edge ratio (R-700/R-670), Transformed Chlorophyll Absorption in Reflectance Index normalized by the Optimized Soil Adjusted Vegetation Index (TCARI/OSAVI), the Photochemical Reflectance Index using reflectance at 530 (PRI) and 515 nm [PRI(570-515)] and the normalized PRI (PRInorm) were obtained from the narrow-band multi-spectral images and the relationship with the in-field measurements explored. …”

Salinity effects on the activities of ROS scavenging enzymes in leaves of two sweet potato clones por Mondal, S., Burgert, S., Asch, J., Rahaman, E.H.M.S., Asch, F.

“…Salt stress may result in excessive uptake of unwanted ions into plant tissues leading to the formation of reactive oxygen species (ROS), which in turn may destroy membranes and reduce photosynthesis and growth. Antioxidant enzymes such as superoxide dismutase (SOD), peroxidase (POX), catalase (CAT), glutathione reductase (GR) and ascorbate peroxidase (APX) scavenge ROS and early changes in the activities of such enzymes could be used to identify salinity tolerant genotypes. …”

How does burning of rice straw affect CH4 and N2O emissions? A comparative experiment of different on-field straw management practices por Romasanta, Ryan R., Sander, Bjoern Ole, Gaihre, Yam Kanta, Alberto, Ma.Carmelita, Gummert, Martin, Quilty, James, Nguyen, Van Hung, Castalone, Angeli Grace, Balingbing, Carlito, Sandro, Joseph, Correa, Teodoro, Wassmann, Reiner

“…Although burning of straw residues emits large amounts of CO2, this component of the smoke is not considered as net GHG emissions and only concludes the annual carbon cycle that has started with photosynthesis. Hence, we focused on emissions of CH4 and N2O from open-field burning against a baseline of straw incorporation. …”

Effects of glyphosate on the movement of assimilates of two Lolium perenne L. populations with differential herbicide sensitivity por Yanniccari, Marcos Ezequiel, Istilart, Carolina Maria, Gimenez, Daniel Oscar, Castro, Ana Maria

“…Glyphosate applications trigger the depletion of aromatic amino acid pools and the decrease of photosynthesis that results in changes in carbon metabolism. …”

The allocation of assimilated carbon to shoot growth: in situ assessment in natural grasslands reveals nitrogen effects and interspecific differences por Xiao, Ying Gong, Berone, German Dario, Agnusdei, Monica Graciela, Rodríguez Palma, Ricardo Manuel, Schäufele, Rudi, Lattanzi, Fernando Alfredo

“…We used a mobile facility to perform steady-state 13C-labeling of field stands to quantify, in winter and autumn, the daily relative photosynthesis rate (RPR~tracer assimilated over one light-period) and A shoot (~tracer remaining in shoots after a 100 degree days chase period) in four individual species with contrasting morpho-physiological characteristics coexisting in a temperate grassland of Argentina, either fertilized or not with nitrogen, and either cut intermittently or grazed continuously. …”

Redox-related metabolites and gene expression modulated by sugar in sunflower leaves: similarities with Sunflower chlorotic mottle virus-induced symptom por Rodriguez, Marianela, Muñoz, Nacira Belen, Lenardon, Sergio Luis, Lascano, Hernan Ramiro

“…Sugars are part of an integrated redox system, since they are key regulators of respiration and photosynthesis, and therefore of the levels of reducing power, ATP and ROS. …”

Nutrient deficiency and hypoxia as constraints to Panicum coloratum growth in alkaline soils por Luna, Dario Fernando, Aguirre, A., Pittaro, Gabriela, Bustos, Dolores Angela, Ciacci, María Belén, Taleisnik, Edith

“…These results show that studies of plant response to alkaline substrates carried out in aerated nutrient solutions can only partially address the complexity of this stress. Photosynthesis and PSII activity were among the physiological mechanisms negatively affected by alkalinity and may be partially responsible for the growth limitations observed in P. coloratum under alkaline conditions.…”

Rootstocks increase grapevine tolerance to NaCl through ion compartmentalization and exclusion por Martin, Leandro Damián, Vila, Hernan Felix, Bottini, Ambrosio Rubén, Berli, Federico Javier

“…Mild and high salinity levels reduced vegetative growth (50 and 70%, respectively), photosynthesis and leaf water content. Midday ΨL reached − 1.16 MPa (moderate water stress) with 100 mM NaCl, which expressed as oxidative damage in mature leaves, thus affecting protein content, membrane integrity and lipid peroxidation. …”

Morphological and physiological traits reveal differential salinity tolerance of two contrasting Glandularia cultivars por Di Filippo, Marina Laura, Baldassini, Pablo, Vila, Hernan Felix

“…Other mechanisms adopted by Dulce Coral to cope with salinity was the maintenance of a higher K+/Na+ and Ca2+/Na+ ratio in its leaves, a lower root:shoot ratio and the maintenance of photosynthesis. Therefore, Dulce Coral could be proposed as a parent for breeding programs with the objective of improving salt tolerance in Glandularia. …”
