Biological basis of tree-ring formation: a crash course
Frontiers in Plant Science, 2016 Wood is of crucial importance for man and biosphere. In this mini review, we present the fundamental processes involved in tree-ring formation and intra-annual dynamics of cambial activity, along with the influences of the environmental factors.

The effect of stem girdling on xylem and phloem formation in Scots pine
Silva Fennica, 2017 Scots pine ( L.) is a resilient, wide spread species. This paper reports on the xylem and phloem cell formation process, before and after, the species was put under artificial stress by stem girdling.

Cambial growth season of brevi-deciduous Brachystegia spiciformis trees from south central Africa restricted to less than four months. [PDF]
PLoS ONE, 2012 We investigate cambial growth periodicity in Brachystegia spiciformis, a dominant tree species in the seasonally dry miombo woodland of southern Africa. To better understand how the brevi-deciduous (experiencing a short, drought-induced leaf fall period)

Antifungal effect and reduction of Ulmus minor symptoms to Ophiostoma novo-ulmi by carvacrol and salicylic acid [PDF]
, 2010 There are still no effective means to control Dutch elm disease (DED), caused by the vascular fungi Ophiostoma ulmi and O. novo-ulmi. Plant phenolics may provide a new strategy for DED control, given their known antifungal activity against pathogens and ...

Using longitudinal survival probabilities to test field vigour estimates in sugar maple (Acer saccharum Marsh.) [PDF]
, 2008 Tree mortality is a major force driving forest dynamics. To foresters, however, tree mortality is often considered a loss in productivity. To reduce tree mortality, silvicultural systems, such as selection cuts, aim at removing trees that are more likely

Seasonal variation of auxin in stem cambial region of Pinus sihestris L.
Acta Societatis Botanicorum Poloniae, 2015 Investigation of auxin from the stem cambial region of adult Pinus silvestris trees by diffusion to agar, and by extraction revealed both seasonal variation and gradients along the stem. Variation in dynamics of auxin efflux and the effect of the size of

Developmental biology of wood formation [PDF]
, 2003 The wood-forming vascular cambium is responsible for the production of a large part of the biomass on this planet. Yet, there is only limited knowledge on how cell proliferation and differentiation in the cambial meristem are regulated.
