Strength Properties of Juvenile and Mature Wood of Twelve Families of Loblolly Pine (Pinus Taeda L.)
The wood mechanical properties of progeny from twelve open-pollinated parent trees were examined. Six families were from parents which had high wood specific gravity and six were from parents which had low wood specific gravity. Thirty-two-year-old trees, that had been planted at Many, Louisiana, were sampled and juvenile and mature wood test specimens were prepared. Maximum crushing strength, ...
متن کاملcohesion and cohesive devices in a contrastive analysis between ge and esp texts
the present study was an attempt to conduct a contrastive analysis between general english (ge) and english for specific purposes (esp) texts in terms of cohesion and cohesive devices. to this end, thirty texts from different esp and ge textbooks were randomly selected. then they were analyzed manually to find the frequency of cohesive devices. cohesive devices include reference, substitution, ...
15 صفحه اولTradeoffs between hydraulic and mechanical stress responses of mature Norway spruce trunk wood.
We tested the effects of growth characteristics and basic density on hydraulic and mechanical properties of mature Norway spruce (Picea abies (L.) Karst.) wood from six 24-year-old clones, grown on two sites in southern Sweden differing in water availability. Hydraulic parameters assessed were specific hydraulic conductivity at full saturation (ks100) and vulnerability to cavitation (Psi50), me...
متن کاملThermomechanical Pulping of Loblolly Pine Juvenile Wood
Intensive forest management, with a heavy emphasis on ecosystem management and restoring or maintaining forest health, will result in the removal of smaller diameter materials from the forest. This increases the probability of higher juvenile wood content in the harvested materials. The purpose of this study was to compare the performance of loblolly pine juvenile and mature wood unbleached the...
متن کاملComparing Crown Growth and Phenology of Juvenile, Early Mature, and Late Mature Metrosideros polymorpha
A large sample of terminal (apical) twigs was marked in a l-yr study of crown growth of juvenile, early mature, and late mature Metrosideros polymorpha Gaud. (Myrtaceae) trees. Populations of terminal twigs in upper crowns ofjuvenile, early, and late mature trees increased by 10%,33%, and 5%, respectively. Vegetative flushing occurred at all times of the year. Length of dormancy before bud-brea...
