Xylem vulnerability to embolism represents an important trait to determine species distribution patterns and drought resistance. However, estimating embolism resistance frequently requires time-consuming and ambiguous hydraulic lab measurements. Based on a recently developed pneumatic method, we...

Drought is considered the main environmental factor limiting productivity in eucalyptus plantations in Brazil. However, recent studies have reported that exposure to water deficit conditions enables plants to respond to subsequent stresses. Thus, this study investigates the ecophysiological...

Elevated atmospheric CO₂ (eC_a) may benefit plants during drought by reducing stomatal conductance (g_s) but any 'water savings effect' could be neutralized by concurrent stimulation of leaf area. We investigated whether eC_a enhanced water savings, thereby ameliorating the impact of drought on carbon ...

Photosynthetic sensitivity to drought is a fundamental constraint on land-plant evolution and ecosystem function. However, little is known about how the sensitivity of photosynthesis to nonstomatal limitations varies among species in the context of phylogenetic relationships. Using saplings of 10 ...

The isohydric-anisohydric continuum describes the relative stringency of stomatal control of leaf water potential (ψ_leaf) during drought. Hydroscape area (HA)-the water potential landscape over which stomata regulate ψ_leaf-has emerged as a useful metric of the iso/anisohydric continuum because it...

This study aimed to evaluate the genetic variability of the selected 25 Eucalyptus clones from germplasm bank of Institute of Forest Genetics and Tree Breeding (IFGTB), using morphological traits which covers qualitative, pseudo-qualitative and quantitative traits by numerical taxonomic methods....

Alterations in plant chemistry underpin a suite of physiological adaptations to arid conditions. Qualitative and quantitative differences in leaf chemistry are found in the genus Eucalyptus correlating with physiological adaptation to aridity. Here we investigate seasonal water relations of three...

Background and aims: Drought-associated vegetation declines are increasingly observed worldwide. We investigated whether differences in water relations can potentially explain the distribution and vulnerability to drought-induced decline of four common tree species in Mediterranean southwestern...

Eucalypts are the most planted hardwood in the world, with 30 million ha. under cultivation. There are approximately 700 species of eucalypts, but more than 90% of the plantations are concentrated in nine species of the Subgenus Symphyomyrtus in the Sections Exsertaria, Latoangulatae and...

Many plants are able to synthesize essential oils (EOs), which play key roles in defense against weeds, fungi and pests. This study aims to analyze the chemical composition and to highlight the antioxidant, antimicrobial and phytotoxic properties of the EOs from Eucalyptus falcata, E. sideroxylon...
