In six dominant species of the Amazonian ‘Bana’ vegetation, leaf blade characteristics, pigment composition, and chlorophyll (Chl) fluorescence parameters were measured in young and mature leaves under field conditions. Leaf δ13C was comparable in the six species, which suggested that both expanding and expanded leaves contained organic matter fixed under similar intercellular and ambient CO2 concentration (Ci/Ca). High leaf C/N and negative δ15N values found in this habitat were consistent…

Gas exchange and chlorophyll a fluorescence measurements of expanding and adult leaves of four plant species were compared under field conditions, suggesting the activation of photoprotective mechanisms.

Leaf Gas Exchange, Photon Capture and Light Harvest in Aldina heterophylla along a Vegetation Gradient in the Amazon Rainforest

The results indicate that the differences in the leaves and soil nitrogen concentrations are not enough to change the levels of gas exchange, and other environmental features may be driving the observed morphological features in this gradient, in particular, the tree height.

Response of photosynthesis and chlorophyll fluorescence quenching to leaf dichotocarpism in Ligustrum vicaryi, an ornamental herb

Net photosynthetic rate of yellow upper leaves (UL) of Ligustrum vicaryi was slightly, but not significantly higher than that of green lower leaves (LL). Diurnally, maximum photochemical efficiency

Leaf traits variation during leaf expansion in Quercus ilex L.

Variation in leaf size during leaf expansion might be attributed to a combination of cells density and length, and it is confirmed by the significant (p<0.001) correlations among these traits.

Cost-benefit relationships in sclerophyllous leaves of the ‘Bana’ vegetation in the Amazon region

A trade-off between investments in an expensive resistant sclerophyllous leaf which should maximize carbon gain in the long term is suggested.

Photosynthetic Traits of Spring Barley throughout Development Stages under Field Conditions

Photosynthetic traits are affected by many environmental factors, of which the most important ones are microclimate of crop stand and meteorological conditions. A 2-year field study was conducted to

Abstract: The objective of this study was to explore the leaf tissue water relations in terminal branches, as well as the relations between xylem structure and function of five sclerophyllous species

Photochemical reflectance index as a mean of monitoring early water stress

The aim of this study was to evaluate the use of PRI as an early water stress indicator and showed a strong correlation between RWCs% and photosynthetic rate, stomatal conductance, NPQ and operating efficiency of PSII but not with PRI when the whole dataset was considered.

A relook into plant wilting: observational evidence based on unsaturated soil–plant-photosynthesis interaction

A new framework for determining permanent wilting point is introduced by integrating plant leaf response and ψ during drought, which found that coarse textured silty sand causes wilting at much lower ψ than clayey loam.

Underestimate of PS2 efficiency in the field due to high leaf temperature resulting from leaf clipping and its amendment

It is found that on a sunny day of subtropical summer, the Fv/Fm ratio was often underestimated because of a large F0 value resulted from a high leaf temperature caused by clipping the leaf under high irradiance, especially for long (e.g. 20 min) duration.

Nutrient Contents, δ^13 C and δ^15 N during Leaf Senescence in the Mangrove, Kandelia candel (L.) Druce

The nutrient quality of the leaf litter originating from K. candel was characterized and the extent to which the observed decline of nutrient concentrations in senescing leaves could be attributed to the withdrawal of these nutrients into the main plant before abscission was suggested.

General morphology, anatomical structure, and nutrient content of sclerophyllous leaves of the ‘bana’ vegetation of amazonas

Species of the ‘bana’ vegetation in the Amazonas region of equatorial South America have scleromorphic leaves which have several features commonly found in xeromorphic plants, including greater leaf and cuticle thickness, pubescent leaves and sunken stomata, and a high incidence of sclerenchyma.
