Abstract Plant functional traits and their effects on rangeland ecosystem function have received much attention by ecologists. However, the importance of functional traits and the interactive effects of grazing exclusion and climate are poorly understood. This study, therefore, aimed to analyse the response of Leymus chinensis functional traits in long-term grazing exclusion in different habitats (rainless typical steppe and rainy meadow steppe). This study showed that although the sensitivity and variability of different traits were similar in two steppe habitats, phenotypic plasticity of L. chinensis in meadow steppe was significantly higher than typical steppes. With the increased degree of plasticity, the… More >

Abstract The objective of this study was to analyze the anatomy of stems and roots of Mnesithea selloana. Free hand cross sections were made from fresh material of reproductive stems and adventitious roots; they were colored with safranin and mounted on glycerin jelly. Observations were made using an Olympus CH2 light microscope and photographed. In cross section, the stems were circular towards the distal end of the synflorescence and semicircular toward the proximal end, and have two ribs. A uniseriate, continuous epidermis presenting a smooth and thick cuticle and no hairs was observed. Parenchyma cells increased in size towards the pith;… More >

Abstract The progress and development of crops like potato are harmfully affected by increased heat stress throughout the world. Stress caused by increased heat adversely affects germination and seedling growth which result in a reduced crop development and yield. The present research was carried out to know the influence of heat stress on growth indices and physiological processes of potato (Solanum tuberosum L.). The heat stresses C- Control (25 °C); T1-45 °C, and T2-40 °C were applied in separate growth chambers to the plants, after 25 days from their germination. Increased heat stress considerably decreased the chlorophyll a and b pigments… More >

Abstract Syntaxin-1 and 25-kDa Synaptosome-associated Protein (SNAP-25) are present in the plasma membrane of several different secretory cell types and are involved in the exocytosis process. In this work, the free-living amoeba Difflugia corona was studied in relation to ultrastructure, structural membrane proteins, and proteins such as Syntaxin-1 and SNAP-25. Our results obtained by scanning electron microscopy in the amoeba without its theca, showed many membrane projections and several pore-like structures. Using immunocytochemistry, we found structural proteins Syntaxin-1 and SNAP-25. More >

Abstract Materials selection is a multiple attribute decision making (MADM) problem. A lot of MADM methods are applicable to materials selection, and it may produce considerable differences between the results of materials selection. But it is unknown which MADM method is better. So it is desirable to decide reasonable final result of materials selection in consideration of the individual results from different MADM methods. In this paper, materials selection method combined with different MADM methods is proposed. The method is based on final ranks of alternative materials, where the final ranks are determined from the ranks of the alternative materials using… More >

Abstract The effect of scarification methods and silver nanoparticles on plantlets growth were tested on seeds of plants belonging to the Fabaceae family (Prosopis laevigata, Acacia farnesiana and Erythrina americana), which are predominant species in semi-arid ecosystems in Mexico. The scarification methods consisted in using coarse sand paper and two different concentrations of sulphuric acid (H₂SO₄ 98% and H₂SO₄ 50%); immersion of seeds in distilled water was used as a control. The percentage of germination was calculated and the Kotowski´s coefficient was determined. After scarification, the seeds were immersed in silver nanoparticles solutions at different concentrations i.e., 100 mg/L, 500 mg/L… More >

Abstract The aim of this investigation was to analyze the effect of vermicompost and phosphate rock on plant growth and biochemical responses of Moringa oleifera exposed to water deficit and waterlogging conditions. Treatments included 152 g of vermicompost (V) and 1.3 g of phosphate rock (PR) added to each cultivation bag. Control was prepared with 2.3 g of urea. All treatments were irrigated under different watering conditions [water deficit: irrigated at 20% water holding capacity (WHC); control (40% WHC) and waterlogging (60% WHC)]. The overall average in plant height was 90, 86 and 68 cm, whereas chlorophyll was 45, 40 and… More >
