The aim of this study was to investigate vegetation composition in broadleaved and conifers plantations in 220 ha of Loblloly pine (Pinus taeda), alder (Alnus glutinosa( and poplar (Popolus deltoides) hardwood plantations and its comparison with natural forests in Bibiyanlu protected forest park, Astara. A total of 60 sampling plots of 1000 m2 were taken using randomly-systematic method with1...
pears (pyrus spp.) belongs to the rosaceae family, which have been cultivated formore than 3000 years. pears are among the most important fruits in all the temperateregions in about 50 countries of the world. the objectives of this study were to classifypear genotypes based on qualitative and quantitative characteristic and determination oftheir genetic distance. evaluation of genetic diversity...

Varga L. (2008): Hercinothrips femoralis (Reuter, 1891) – a new pest thrips (Thysanoptera: Panchaetothripinae) in Slovakia. Plant Protect Sci., 44: 114–118. Monitoring of pest species in plant production and extended trade on ornamental plant material, including precise identification, are the main goals of modern plant protection. As a result, a new species of phytophagous thrips – Hercinothri...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Frankia strains symbiotic with Ceanothus present an interesting opportunity to study the patterns and causes of Frankia diversity and distribution within a particular host infectivity group. We intensively sampled Frankia from nodules on Ceanothus plants along an elevational gradient in the southern Sierra Nevada of California, and we also collected nodules from a wider host taxonomic and geogr...
the present study aimed to investigate the possible effects of focused highlighted error feedback on grammatical accuracy of writing among iranian intermediate efl learners. after selecting 52 homogenous participants from among 70 university students attending azad university of rasht and randomly dividing them into two intact groups of 26 students, the researcher exposed the participants of th...
Branching in temperate plants is closely linked to bud fates, either floral or vegetative. Here, we review how the fate of meristematic tissues contained in buds and their position along a shoot imprint specific branching patterns which differ among species. Through examples chosen in closely related species in different genera of the Rosaceae family, a panorama of patterns is apparent. Pattern...
The response of soil properties to vegetation types is still not well understood and the relationship between vegetation types and soil properties has not been quantified in highland grasslands. A field experiment was conducted in highland grassland of the Loess Plateau in China to study the distribution of soil properties under different vegetation. 22 plant communities totaling 17 species tha...
Iran, possessing unique topographic and diverse climatic conditions, is the home of 8167 vascular plant species. Iran has a historical tradition in using plants for medicinal purposes. Approximately 2075 species over whole are popularly characterized as or aromatic. Medicinal trees shrubs compose significant percentage Iranian flora. Nonetheless, there no integrated databases on their applicati...
