Cambial activity of Dipterocarpus costulatus in relation to different stem diameters and climate factors [PDF]
, 2014 This study investigated the seasonal cambial activity in Dipterocrpus costulatus trees with different range of stem diameter at breast height (dbh). Samples from main stem of D.

Agricultural and Forest Entomology, EarlyView.Damage caused by Phoracantha mastersi larvae are the primary cause of forest decline in Australia's subalpine forests. Behaviour of male adult beetles was tested in response to a suite of commercial semiochemicals and conspecifics engaged in active copulation within a Y‐maze.

Entomologia Experimentalis et Applicata, EarlyView.The emerald ash borer (EAB), Agrilus planipennis, threatens ash trees in North America and Europe. To assess the role of temperature on EAB reproduction, we reared adults at one of four temperatures (12°C, 15°C, 18°C, and 21°C) and measured reproductive success.

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

Molecular factors involved in the formation of secondary vascular tissues and lignification in higher plants [PDF]
, 2003 The formation of secondary vascular tissues involves complex processes and many steps, a number of which have been examined in detail in this study. A novel CuZn-SOD, with a high pI and thus denoted hipI-SOD, was identified and characterized in Pinus ...

Journal of Applied Entomology, EarlyView.ABSTRACT Norway spruce will likely remain an important tree species in Europe over the next few decades despite efforts to transform forests and reduce its distribution range more to its natural range. Consequently, Ips typographus will remain one of the most relevant forest pests the management of which will become increasingly challenging due to ...

Intra-annual cambial activity and carbon availability in stem of poplar [PDF]
Tree Physiology, 2009 Cambial activity is influenced by many environmental and physiological factors and among them, carbon acts as a source of energy for the growing meristems. This work has focused on the intra-annual stem growth of poplar compared with the carbon available for xylogenesis processes in cambium and outer wood.

Journal of Applied Entomology, EarlyView.ABSTRACT Flatheaded borers (Coleoptera: Buprestidae) are largely xylophagous insects. Larvae of flatheaded borers tunnel into the trunks of trees, with boring and feeding damage eventually appearing on the surface as discolored bark, sunken areas, bark splits or bark sloughing.

Apical control of xylem formation in the pine stem. I. Auxin effects and distribution of assimilates
Acta Societatis Botanicorum Poloniae, 2014 The effect of IAA upon cambial activity, xylem differentiation and translocation of assimilates from the lateral shoot was investigated in spring and late summer in decapitated and ring-barked young trees of Pinus silvestris in the forest stand ...
