The effects of fire severity on ectomycorrhizal colonization and morphometric features in Pinus pinaster Ait. seedlings

Sawing simulation of Pinus pinaster Ait

The paper deals with the sawing simulation of Maritime pine (Pinus pinaster Ait.) and is a report from a project aiming to increase the knowledge in how different raw material characteristics and sawing factors are affecting on the sawing yield of Maritime pine. The conversion was executed by an integrated optimising software system, WooDCIM® developed at VTT Technical Research Centre of Finlan...

Influence of copper on root growth and morphology of Pinus pinea L. and Pinus pinaster Ait. seedlings.

We assessed the effects of Cu on root growth and morphology of stone pine (Pinus pinea L.) and maritime pine (Pinus pinaster Ait.) seedlings grown in culture solutions supplied with 0.012 (control), 0.1, 1 or 5 micro M CuSO(4). The presence of 5 micro M Cu in the nutrient solution completely inhibited root growth of both species within 3 days. In both species, taproot elongation was reduced in ...

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
