Seasonality of cambial activity in lianas

open access: yes, 2012
Introdução e objetivos Apesar de ser um importante componente estrutural de florestas tropicais e causar impactos na dinâmica e funcionamento destas florestas, pouco se sabe sobre a sazonalidade do crescimento de lianas em seu ambiente natural.

Metabolomics and wood development [PDF]

open access: yes, 2013
The tree industry is one of Sweden's most important economic sectors, producing pulp, paper, wooden goods and wood as a bioenergy source. Understanding the biology behind the processes of tree growth and wood development is a key to maximizing the use of

Endogenous oscillations of electric potential difference in the cambial region of the pine stem. I. General characteristics of the oscillations

open access: yesActa Societatis Botanicorum Poloniae, 2014
Extracellular measurements of electric potential difference (PD) in isolated tissue blocks from Scots pine were performed. Endogenous transient PD changes (oscillations) generated exclusively in the cambial region were found.

Life‐history traits and phylogeny structure taxon‐specific species–substrate relationships in deadwood

open access: yesOikos, EarlyView.
To understand the structuring of species assemblages, integrating life‐history traits and evolutionary heritage in analyses is vital. This allows the assessment of a mechanistic link between species and their environment. Deadwood systems are vital for nutrient cycling and biodiversity support, governed by complex intra‐ and inter‐specific fungal and ...

CAMBIAL ACTIVITY IN POPLAR WITH PARTICULAR REFERENCE TO POLARITY PHENOMENA

open access: yes, 1936
Ringing experiments with the aspen poplar, Populus tremuloides Michx., lead to the conclusion that cambial activity is definitely not rigidly or unconditionally polar in its development in the root.

Investigation of the Evolution Mechanism and Multiphysics Coupling in Tree‐Contact Single‐Phase‐to‐Ground Fault

open access: yesHigh Voltage, EarlyView.
ABSTRACT Tree‐contact single‐phase‐to‐ground fault (TSF) is a common and hazardous type of failure in distribution networks. TSF is likely to occur when overhead conductors contact moist tree branches, potentially leading to insulation breakdown, posing serious threats to grid safety.

Origin of Intra-annual Density Fluctuations in a Semi-arid Area of Northwestern China

open access: yesFrontiers in Plant Science, 2021
Intra-annual density fluctuation (IADF) is a structural modification of the tree ring in response to fluctuations in the weather. The expected changes in monsoon flow would lead to heterogeneous moisture conditions during the growing season and increase ...

Conductivity Analysis and Thermoelectric Behaviour of Larch Standing Trees Under Lightning Currents: Role of Moisture Distribution and Carrier Motion

open access: yesHigh Voltage, EarlyView.
ABSTRACT The direct effects of lightning strikes on forest combustibles form the foundation for predicting lightning‐induced forest fires. Accurate assessment of lightning impact is hindered by limited knowledge of the conduction characteristics of standing larch trees.

Concomitant analysis of cambial abscisic acid and cambial growth activity in poplar [PDF]

open access: yes, 2018
Endogenous levels of cambial region abscisic acid (ABA) were quantified by immunoassay and assessed together with cambial growth activity in poplar (Populus nigra L.×P. maximowiczii Henry, clone Kamabuchi) over the course of a growing season.

Humble beginnings of the Australian giant wood moth (Endoxyla cinereus): A century‐old mystery solved

open access: yesInsect Science, EarlyView.
The Australian giant wood moth (Endoxyla cinereus) feeds within the galls of scale insects (Apiomorpha) before transitioning into its wood‐boring eucalypt larval phase. This transitionary phase may be key to its multi‐year development, at the end of which it can produce over 100 000 eggs.
