The following diagnostic features were identified: leaf—isolateral-palisade type of mesophyll leaf;thick-walled outer walls of the epidermis;the outline of epidermal cells is rectilinear, the projection is polygonal;amphystomatic leaves;submerged numerous stomata of hemiparacitic and anomocytic type;chlorophyll-bearing palisade and spongy parenchyma;closed collateral type of vascular bundles and more sclerified, due to sclerenchymal cells. Thorn—parenchymal-beam type of structure;thin-walled outer walls of the epidermis;under the epidermis is a lamellar collenchyma;closed collateral type of vascular bundles and more sclerified, due to sclerenchymal cells. The complex of the above features reflects the species specificity of the structure of the leaf and spines. Identified and described features that can be used in the taxonomy of the studied tribes and can serve to identify plant materials.展开更多

The results reveal large variability in fiber cell morphology and fiber cell dimensions. The species are classified on the basis of its fiber cell morphology and fiber cell length and recommended for their possible utilization for different purposes. Wood having fibre cells with broad lumen and thin wall could be suitable for the manufacture of paper documented in the literature viz. Acacia farnesciana, Caesalpinia mexicana, Cordia boisiieri, Diospyros palmeri, Forestieria angustifolia, Morus celtifolia, Prosopis laevigata. This technique can be used in preliminary screening of woody species for its utilization for different purposes. Further studies are needed to confirm.展开更多

Various factors affect the decline in crop productivity. Where weeds are the most important reasons that cause a huge loss in crop productivity. Studying agricultural ecosystems, knowing their components and explaining the relationship between all of their components, helps a lot in achieving the highest productivity of different crops in addition to benefiting from some types of weeds, as well as, identifying appropriate methods to control the growth of weeds. In this study, 60 species were listed. The most frequent plant families were Asteraceae, Poaceae and Zygophyllaceae. Annuals were the most common life span, as well as, therophytes were the most frequent life form. The most frequent floristic categories were Saharo-Sindian-Sudano-Zambezian and Saharo-Sindian regions. The most famous indicators of biodiversity (species richness, species evenness and species diversity) have been calculated. For managing and classifying data PC-ORD program (TWINSPAN and DCA analyses) was used.展开更多

There are many kinds of writer＇ s creation styles, among which the national style is a very prominent level, which can very excellently reflect the cultural characteristics of a nation. The Thorn Birds, which was created by Australian author Lynn McCullough, has the characteristics of a very strong national style. In the works, the national style of Australia is very well reflected from the depiction of the natural environment, the composition way of the novel, and the shape of character image.展开更多
