Drought impact on wood formation and antioxidant protection of Scots pine cambial zone [PDF]
Сибирский лесной журнал, 2015 The effect of drought on the 8-9-year-old seedlings of Scots pine (Pinus sylvestris L.) was simulated in the field by isolating trees from precipitation.

Gibberellin-Mediated Synergism of Xylogenesis in Lettuce Pith Cultures [PDF]
Plant Physiology, 1987 Major gibberellins (GAs) in lettuce (Lactuca sativa L. cv Romaine) pith explants have been identified by gas chromatography-mass spectrometry (GC-MS) or GC-selected ion monitoring (GC-SIM) as GA(1), 3-epi-GA(1), GA(8), GA(19), and GA(20). Treatment of pith explants with indole-3-acetic acid (IAA) (57 micromolar) plus kinetic (0.5 micromolar) induced ...

Intra-annual transfer of hydrogen and oxygen isotopic signals from water and sugar precursors to tree rings: Processes and mechanisms. [PDF]
New PhytolIntra‐annual radial growth of beech and spruce in 2021 and 2022. Summary The oxygen (δ18O) and hydrogen (δ2H) isotope compositions of leaf and xylem water shape tree‐ring isotope baselines, while the fraction of sugars undergoing isotopic modification downstream of leaves (fO, fH) determines the dominant hydrologic signal.

On growth and flow: hydraulic aspects of aboveground meristems. [PDF]
New PhytolSummary Water is essential for plant growth under both normal and stress conditions. Aboveground, two key meristems control plant development: the shoot apical meristem and the vascular cambium. Here, stem cell maintenance and cell differentiation are affected by hydraulic fluctuations across seasons, days, or even hours. Water fluxes, turgor pressure,

Xylogenesis of Pinus pinaster under a Mediterranean climate [PDF]
Annals of Forest Science, 2013 & Context The knowledge on cambial activity in water-limited environments, such as the Mediterranean, is still fragmentary. Dendrochronological studies have determined that spring precipitation plays an important part in determining tree-ring width and the properties of tracheids.

Xylem Cell Wall Formation in Pioneer Roots and Stems of Populus trichocarpa (Torr. & Gray)
Frontiers in Plant Science, 2019 Regulation of gene expression, as determined by the genetics of the tree species, is a major factor in determining wood quality. Therefore, the identification of genes that play a role in xylogenesis is extremely important for understanding the ...
