Polyploidy is very common within angiosperms, and several studies are in progress to ascertain the effects of early polyploidization at the molecular, physiological, and phenotypic level. Extensive studies are available only in synthetic allopolyploids. By contrast, less is known about the consequences of autopolyploidization. The current study aimed to(More)
Intra-annual density fluctuations (IADFs) are anomalies of tree rings where wood density is abruptly altered after sudden changes in environmental conditions. Their characterisation can provide information about the relationship between environmental factors and eco-physiological processes during tree growth. This paper reports about the variability of(More)
Tree rings provide information about the climatic conditions during the growing season by recording them in different anatomical features, such as intra-annual density fluctuations (IADFs). IADFs are intra-annual changes of wood density appearing as latewood-like cells within earlywood, or earlywood-like cells within latewood. The occurrence of IADFs is(More)
Wood fibres are as sensitive to environmental conditions as vessels in tree rings with intra-annual density fluctuations (IADFs) in Mediterranean species. Forecasted environmental changes are likely to increase the frequency of intra-annual density fluctuations (IADFs) in Mediterranean tree rings. The interpretation of intra-annual anatomical variability of(More)
Our study aims to define isotopic and anatomical responses to fires of P. halepensis . Main results: decrease in tree growth and relative conductivity and increase in water use efficiency. We investigated the ecophysiological responses of a Pinus halepensis Mill. stand surviving two wildfires in southern France. Basal area, isotope composition and(More)
Polyploidy is an important factor in plant evolution that may trigger drastic genome reorganization and phenotypic differentiation. In the last decade, extensive studies have been carried to understand the consequences of allopolyploidization, where the effects of ploidy change may be confounded by interspecific hybridization. By contrast, less is known on(More)
The presence of NaCl in soil or water is one of the most critical environmental stresses limiting crop productivity worldwide. Seaweed extract (SWE) represents an important category of plant biostimulants able to improve crop tolerance to abiotic stresses, such as salinity. The current research aimed at elucidating the physiological and anatomical effects(More)
The response of higher plants to ionising radiation depends on factors related to both radiation properties and plant features including the species, cultivar, age, and structural complexity of the target organ. Adult plants of dwarf tomato were irradiated with different doses of X-rays to investigate the possible variations in leaf morpho-anatomical(More)
The analysis of the growth behaviour, wood anatomical, and eco-physiological traits of two Bougainvillea genotypes, trained to two shapes and subjected to different irrigation regimes, fully supports the idea that structural properties interact with cultural practices (i.e., training) in determining the adaptive capability of plants, hence their(More)
