Key messageDouble-stained microsections from highaltitudePinus nigrawood cores highlighted unlignified latewood cells possibly linked to abrupt temperature reduction at the end of the growing season. More consolidated detection could increase their role in dendroecology. Abstract Cambial activity...
Key messageThis review article contributes in more understanding of most aspects ofCalotropis procerabiology and extend our knowledge about its behavior. Abstract Calotropis procera (Aiton) W.T (Asclepiadaceae) (Giant milkweed) is a xerophytic perennial shrub or small tree. It is native to tropical and subtropical Africa,...
Key messageThe density-integral approach worked well for estimating whole-tree and dominant stem vertical biomass profiles, and performed better than the constant-density approach for biomass prediction. Abstract Integrated whole-tree biomass equations are in great demand due to the simultaneous need to improve estimation of forest carbon stocks and to quantify the...
Key messageTranspiration in conifer species was controlled by wind speed, similar to broadleaf species, indicating that caution is required when using the simplified Penman–Monteith equation. Abstract The significance of aerodynamic controls on tree transpiration ( E ) is critical when modeling E using the simplified Penman–Monteith equation...
Key messageComparative proteome analysis revealed the proteins that are differentially expressed during the processes of tetraploid black locust (Robinia pseudoacaciaL.) adventitious root formation, which are involved in carbohydrate binding, energy and metabolism, and stress response. Abstract The tetraploid black locust (...
Key messageLeaf to sapwood area ratio inCastanea sativais constant within a branch, but decreases with branch height. We propose a modeling approach to mitigate this effect. Abstract The pipe model theory postulates the constancy of the relationship between leaf to sapwood area among single parts and for a whole tree. By analyzing 218 branches...
Key messageThe most dangerous stage of cryopreservation of embryonic axes of maple seeds is tissue dehydration, as excessive desiccation leads to membrane lipid peroxidation and irreversible loss of semi-permeability. Abstract We attempted cryopreservation of the embryonic axes (EAs) from orthodox seeds of Acer platanoides (Norway maple) and recalcitrant...
Key messageFoliage clumping can be estimated from logarithm averaging method in LAI-2000. The spatial scaling of clumping effects considered by the instrument is dependent on the sensor’s azimuthal view. Abstract Accurate estimates of foliage clumping index ( Ω ) are required to improve the retrieval of leaf area index ( L ) from...
Key messageAnalyses of tree-ring anatomical features showed to be more sensitive to specific intra-seasonal environmental factors than tree-ring width inTectona grandisandPinus caribaeagrowing in a subtropical region. Abstract Earlywood vessels (EWV) and intra-annual density fluctuations (IADFs)...
Key messageUnderstanding the mobility and distribution of chemical elements in wood is necessary to apply dendrochemistry. Crystals are likely stable and could be used to analyze changes in nutrient supply. Abstract Dendrochemistry uses the variation in wood chemical composition to infer about past environmental conditions and possible effects on tree growth. Elemental...
Key messageRed spruces are less severely impacted by the parasite eastern dwarf mistletoe than white spruce. Differences in stem vulnerabilities to cavitation do not seem to explain this pattern. Abstract Parasitic dwarf mistletoes are damaging forest pathogens, yet the physiological mechanisms by which infections contribute to host decline remain poorly...
Key messageThis study shows that two emergent tree species growing in a nutrient-limited tropical peat swamp forest use different mechanisms for nutrient regulation. Abstract The main aim of this study is to understand the contribution of litterfall to nutrient supply and regulation of two emergent tree species in a tropical peat swamp forest (TPSF) in Peninsular Malaysia...
Key messageAcaciasenegalandAcacia seyalpresent different drought stress coping mechanisms that are independent of substrate fertility. Higher substrate fertility increased aboveground plant growth, even with low watering. Abstract The potential of native African tree species for...
Key messageThis manuscript describes the characteristics and climate-growth responses of Chinese pine in different age classes; and determines the climate-growth response of Chinese pine in North China is age independent. Abstract The Chinese pine ( Pinus tabulaeformis Carrière) is a widespread conifer species in North China and has been widely...
Key messageAccording to biomechanical processes, tree morphology (trunk inclination, height-to-diameter ratio and crown area) explains statistically silvicultural effects on growth stress variation. Abstract Growth stresses constitute the main mechanism allowing the tree to control its posture against its mechanical environment, but are also among the most...
Key messageThe study describes an efficient regeneration system and encapsulation of nodal segments inF. caricaaccompanied with frequent root formation in microshoots under the influence of salicylic acid. Abstract The present study describes an improved protocol for clonal propagation and a short-term conservation strategy using an encapsulation...
Key messageBesides stem temperature, seasonality and vertical gradient in stem diameter growth strongly affect both seasonal and vertical variations in stem CO2efflux. Abstract Stem CO 2 efflux ( Es ) is known to vary seasonally and vertically along tree stems. We measured Es ...
Key messageThis study shows that deficit irrigation can be encouraged in productive activities like plant nursing, especially with the most resistant species. Abstract Drought acclimation is attained by avoidance mechanisms in the short term and by adaptation changes in the long term. In this study, we applied deficit irrigation at nursery stage to elicit species-specific...
Key messageGenetic diversity ofMonoon tirunelvelienseis reported here from India to facilitate its conservation and to take up such studies for conserving threatened plants from different parts of the world. Abstract As endemic and threatened species are susceptible to loss of genetic variation due to stochastic factors, investigation was...
Key messageWe aim to develop, for the first time, poplar species-specific mitochondrial SNP markers which can be employed as diagnostic tool, e.g., to identify mitochondria belonging to different poplar species used in protoplast fusion experiments and for population genetics approaches. Abstract In most higher plant species, the inheritance of chloroplasts and mitochondria...
