Critical steps and troubleshooting in sample preparation for wood and phloem formation: from sampling to microscopic observation

Les, 2022
We present a technical note that supplements published procedures on optimal sample preparation for performing wood and phloem formation analyses. Before beginning sampling, it is important to learn about the characteristics of the tree or shrub species

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.

Adjustment capacity of maritime pine cambial activity in drought-prone environments. [PDF]

PLoS ONE, 2015
Intra-annual density fluctuations (IADFs) are anatomical features formed in response to changes in the environmental conditions within the growing season.

The effects of throughfall exclusion on xylogenesis of balsam fir [PDF]

Tree Physiology, 2013
A 20-40% reduction in soil moisture is projected for the boreal forest of Eastern Canada for the period 2070-99 relative to 1971-2000. In order to better predict the effects of a reduced water supply on the growth of balsam fir (Abies balsamea (L.) Mill.), a dominant tree species of the boreal forest, we simulated 2 consecutive years of summer droughts

Phloem- and xylogenesis in Scots pine stems in the post-fire period [PDF]

Сибирский лесной журнал, 2023
The influence of natural ground fire of varying intensity on the growth processes in the stems of Scotch pine (Pinus sylvestris L.) trees growing in the Krasnoyarsk forest-steppe was studied. The primary reaction is the decrease in the number of cells in

Plant-Programmed Cell Death-Associated Genes Participation in Pinus sylvestris L. Trunk Tissue Formation

Plants, 2022
Molecular genetic markers of various PCD (programmed cell death) variants during xylo- and phloemogenesis have been identified for the first time in Scots pine under lingonberry pine forest conditions in Northwest Russia (middle taiga subzone).

Xylogenesis in black spruce: does soil temperature matter? [PDF]

Tree Physiology, 2011
In boreal ecosystems, an increase in soil temperature can stimulate plant growth. However, cambium phenology in trees was better explained by air than soil temperature, which suggested that soil temperature is not the main limiting factor affecting xylogenesis.

Seasonal Vascular Tissue Formation in Four Boreal Tree Species With a Focus on Callose Deposition in the Phloem

Frontiers in Forests and Global Change, 2019
We studied the seasonal dynamics of xylem and phloem formation in four boreal tree species that differed in leaf phenology (evergreen vs. winter-deciduous) and wood anatomy (angiosperms vs. gymnosperms).

Intra-annual dynamic of opposite and compression wood formation of Pinus massoniana Lamb. in humid subtropical China

Frontiers in Forests and Global Change, 2023
Radial growth of trees can result in opposite wood (OW) and compression wood (CW) due to the varying impact of stem mechanical stress, such as that caused by gravity or wind.

Catechin promotes growth of Arabidopsis thaliana with concomitant changes in vascular system, photosynthesis and hormone content

Biologia Plantarum, 2011
Catechin is associated with several functions in animal and plant systems, with little information available regarding its role in plant growth. Low concentrations of catechin (50 and 100 μM) were found to enhance length of primary and lateral roots ...
