fire, as a natural ecological disturbance factor in forest, this study located in the marivan region, northern zagros forest, and western iranian state of kurdistan. in each burned and unburned area 30 circle sample plot (1000 m2) were collected by randomized–systematic method in the 100×200 m net (in total 60 plots). in every sample plot the kind of species, number of tree, the height of coppi...

Abstract Aims Cropland agroforestry systems are land-use with numerous environmental advantages over monoculture croplands including promotion of soil life. This study aimed to investigate tree-species and tree-distance effects on biota in a temperate system. Methods Our was conducted at paired alley-cropping cropland The tree rows the system comprised blocks poplar Fritzi Pauley, Max 1 or blac...

In this study, 253 of 18S rDNA sequences, 155 ITS2 63 rbcL and 23 tufA sequences were collected on GenBank to evaluate analyse the taxonomic complexity Chlorella clade. C. vulgarisand sorokiniana had most DNA barcoding. Analysis phylogenetic tree results showed that strains these two species divided into 2 3 small groups with genetic differences. addition, different belonging same clade in tree...

Adventitious rooting is an essential step in the vegetative propagation of economically important horticultural and woody species. Populus has emerged as an experimental model for studying processes that are important in tree growth and development. It is highly useful for molecular genetic analysis of adventitious roots in trees. In this short review, we will highlight the recent progress made...

n the present work, isolation and identification of some plant beneficial bacteria vermicompost were conducted. A total ten bacterial isolates selected characterized morphologically biochemically. Molecular characterization using 16S rRNA gene sequence analysis phylogenic tree According to percentages homology with closest NCBI strain, all belonged six species (

OBJECTIVES To evaluate the resolution and reliability of the rpsA gene, encoding ribosomal protein S1, as a novel biomarker for mycobacteria species identification. METHODS A segment of the rpsA gene (565 bp) was amplified by PCR from 42 mycobacterial reference strains, 172 nontuberculosis mycobacteria clinical isolates, and 16 M. tuberculosis complex clinical isolates. The PCR products were ...

To optimize nursery practices for efficient plant production procedures and to keep up to the ever growing demand of seedlings, identification of the most suitable species of arbuscular mycorrhizal fungi (AMF), specific for a given tree species, is clearly a necessary task. Sixty days old seedlings of Neem (Azadirachta indica A. Juss) raised in root trainers were inoculated with six species of ...

0099-1112/12/7810–1079/$3.00/0 © 2012 American Society for Photogrammetry and Remote Sensing Abstract We developed a neural network based approach to identify urban tree species at the individual tree level from lidar and hyperspectral imagery. This approach is capable of modeling the characteristics of multiple spectral signatures within each species using an internally unsupervised engine, an...

BACKGROUND Female sand flies of subgenus Adlerius are considered as probable vectors of visceral leishmaniasis in Iran. The objective of this study was to determine the morphological and genotypic variations in the populations of this subgenus in the country. METHODS Sand flies collected using sticky traps from 17 provinces during 2008-2010. The morphometric measurements were conducted with a...
