Eucalyptus globulus (Myrtaceae) originated in Australia and has been introduced in countries with temperate weather in order to obtain wood for cellulose extraction and building purposes. In this work, we analyzed the potential stimulation of growth in height and trunk diameter as well as the content of holo-cellulose, α-cellulose (long cellulose chains), essential oils and polyphenolic compoun...

The impact of gnawing by Microcavia australis on the survival of Geoffroea decorticans plants was studied in the Monte Desert of Argentina. Sampled ( ) plants N s 105 were selected randomly from two different colonies of M. australis. For each plant sampled the following properties were measured: the diameter of the trunk at ground level; the distance to the nearest burrow of M. australis; the ...

Nacrtak Rot is one of the most important defects in timber assortments of Norway spruce (Picea abies). With the aim to investigate this phenomenon, we analyzed 1,334 spruce trees from 65 locations across Slovenia. The study showed that the incidence of rot was higher in even-aged stands compared to uneven-aged stands. Lower-trunk rot (for the purpose of this study, lower-trunk rot is rot that a...

many characteristics of pear trees such as growth, fruit size and yield, are influenced by the genetic characteristic of the rootstocks. in iran, mainly european pear seedlings (pyrus communis l.) are used as the rootstock in the pear orchards. thus, evaluation of pear seedling rootstocks is an important task. this experiment was conducted in 2009 and 2010 growing seasons in order to explore th...

this study was conducted with the main purpose of investigating genetic variation among 13 selected sweetcherry (prunus avium cv. siah mashhad) genotypes, i.e., the most important iranian sweet cherry cultivars based on their pomological, morphological, and phonological characteristics. the experiment was laid out in a randomized complete block design with three replications at khorasan-e-razav...

Epidermal cyst is the most commonly observed cutaneous tumor. It usually involves the scalp, neck, face, back, and trunk. A commonly seen epidermal cyst is usually a slow-growing tumor of a diameter of 1-2 cm. Cysts with a diameter of more than 5 cm have rarely been reported in the literature. Herein we report a case of a giant epidermal cyst localized in the scalp of the occipital area, diagno...

As part of a project to develop predictive ecosystem models of United Kingdom woodlands we have collated data from two United Kingdom woodlands - Wytham Woods and Alice Holt. Here we present data from 582 individual trees of eight taxa in the form of summary variables relating to the allometric relationships between trunk diameter, height, crown height, crown radius and trunk radial growth rate...
