Summary This study addresses relationships between leaf phenology, xylogenesis, and functional xylem anatomy in two ring‐porous oak species, the temperate Quercus robur sub‐Mediterranean Q. pyrenaica . Earlywood vessel ( EV ) formation phenology were monitored 2012 2013. Ten individuals per species sampled at each of three sites located NW Iberian Peninsula. areas measured on microcore sections used to calculate hydraulic tree diameter D h ), order model phenology. Thermal requirements...
Summary Environmental conditions and the structure of dormant cambium are assumed to affect seasonal patterns cambial activity, hence controlling allocation non‐structural carbohydrates ( NSC ) growth. However, dynamics xylogenesis, their connections with content size, have been rarely assessed along an environmental gradient. We monitored xylogenesis leaf phenology during 2012 2013, in 2012, for drought‐sensitive Quercus robur drought‐tolerant pyrenaica a water‐availability gradient...
Abstract. Non-structural carbohydrates (NSC) play a central role in the construction and maintenance of tree's vascular system, but feedbacks between NSC status trees wood formation are not fully understood. We aimed to evaluate multiple dependencies among anatomy, winter NSC, phenology for coexisting temperate (Quercus robur) sub-Mediterranean (Q. pyrenaica) oaks along water-availability gradient NW Iberian Peninsula. Sapwood concentrations were quantified at three sites December 2012 (N =...
Summary The kinetics of wood formation in angiosperms are largely unknown because their complex xylem anatomy precludes using the radial position vessels and fibers to infer time differentiation. We analyzed xylogenesis ring‐porous ash ( Fraxinus angustifolia ) diffuse‐porous beech Fagus sylvatica over 1 yr proposed a novel procedure assess period vessel fiber enlargement referential file (RRF). Our approach captured dynamics provided robust estimation enlargement. In beech, had similar...
Despite lignin being a key component of wood, the dynamics tracheid lignification are generally overlooked in xylogenesis studies, which hampers our understanding environmental drivers and blurs interpretation isotopic anatomical signals stored tree rings. Here, we analyzed cell wall formation silver fir (Abies alba Mill.) tracheids to determine if lags behind secondary deposition. For this purpose, applied multimodal imaging approach combining transmitted light microscopy (TLM), confocal...
Tree-ring anatomy, microdensity and isotope records provide valuable intra-annual information. However, extracting signals at that scale is challenged by the complexity of xylogenesis, where two major processes - cell enlargement wall thickening occur different times rates. We characterized space-for-time association in tree rings three conifer species examining duration, overlapping, inter-tree synchronicity interannual stability during across regular tree-ring sectors (portions equal...
Abstract Background and Aims The onset of spring growth vessel formation were examined within three deciduous woody plant species, Acer rubrum, Populus balsamifera ssp. trichocarpa Quercus rubra. We broadly interested in the lag between girth expansion mature hydraulically conductive vessels new xylem. Methods Dendrometers installed on 20 trees (6–7 per species), both bole distal stems was monitored throughout growing season a common garden. For each four to six harvested every other week...
ABSTRACT The wood anatomy of Copaifera lucens Dwyer was studied with an emphasis on its growth ring boundaries. Growth rings are visible to the naked eye and demarcated by marginal parenchyma bands and, sometimes, thick-walled fibers in latewood. Secretory canals associated bands, but not all canals. Paratracheal is vasicentric lozenge-aliform. Rays 1–4-seriate, heterocellular non-storied. Vessels eye, diffuse, predominantly solitary, some multiples, sometimes filled gums. Crystals present....
