In this study, we synthesized magnetic activated carbon (MAC) derived from Litsea glutinosa seeds, which was applied to eliminate methylene blue and nickel ions in the aeration tank of the biological treatment system. Structural characteristics and adsorption properties of MAC were studied. The obtained results revealed that the removal efficiency of these pollutants significantly improved as a combination of MAC and activated sludge, especially in the case of nickel ions removal.

In ebook "Ecophysiology of high salinity tolerant plants (Tasks for vegetation science 40)" the halophytes are highly specialized plants, which have greater tolerance to salt. They can germinate, grow and reproduce successfully in saline areas which would cause the death of regular plants. Most halophytic species are found in salt marsh systems along seashores or around landlocked inland lakes and flat plains with high evaporation.

Quinoa (Chenopodium quinoa Willd.) is a pseudo cereal crop, which is considered a new alternative crop due to its high nutritional value and tolerance to environmental stresses. Its seeds are rich in proteins and amino acids (e.g., lysine, threonine, and methionine) that are deficient in other pseudo-cereal crops. It also contains essential fatty acids, such as linoleic, and alpha-linolenic acids, and high quantities of vitamins, e.g., riboflavin (B2), and tocopherol (vitamin E), and inorganic nutrients.

Najas indica (Willd.) Cham. is a freshwater submerged aquatic vegetation. N. indica is an annual plant. Therefore, seeds in the sediment and the survival and growth of seedlings play an important role in reestablishing new populations of the species. The purpose of this study was to determine the seed density in the sediment, examine the effect of salinity on seedling germination from seeds, and assess the impact of the salinity on the growth of early seedlings of N. indica under the experimental condition.

Camellia luuana Orel & Curry is known only from its type locality, Ta Dung Nature Reserve, now Ta Dung National Park, Dak Nong Province, the Central Highlands of Vietnam. No characteristics of fruit and seeds, which are the most important to divide genera in Theaceae (Chang & Ren, 1998; Ming & Bartholomew, 2007; Sealy, 1958), were presented in its protologue.

This study also showed comparatively higher solubility percentage in ‘BARI TPS-1’ tuber than the other local varieties, suggesting rapid disruption of swollen starch granule and faster starch degradation in TPS than the other local potato starches. Scanning Electron Microscope (SEM) images of starch granule showed rapidly ruptured and clumped starch granules in ‘BARI-TPS-1’ than the others, indicating TPS starch might obtain gelatinization temperature within a shorter period of microwave heating than that of the other varieties.

Open-field farming involves successive major processes such as preparation of soil, planting the seed, adding pesticides and fertilizers, irrigation, cultivation, and harvest. The main aim of all processes is to achieve maximum yield out of the available agricultural landscape. It is necessary to collect geo-referenced descriptive data on soil characteristics, such as soil penetration resistance and electrical conductivity before starting all these processes.

The degree of dense planting affects the respiration characteristics of alfalfa artificial grassland. In the process of alfalfa seed production, high plant and multibranch forage can be obtained by reasonable close planting. Therefore, an analysis method of the effect of reasonable close planting on respiration characteristics of garden alfalfa artificial grassland is put forward. In this method, the density characteristics of alfalfa planting were determined from three aspects of plant horizontal density, vertical density and three-dimensional density.

Micromorphological characteristics of 13 Trifolium species, which are grown in the province of Bolu, were examined using a scanning electron microscope (SEM). The morphological characteristics determined from the study were subjected to morphometric analyses and their variation spectrums were defined. Tricolporate pollen grains showed two pollen shapes, prolate and subprolate, according to equatorial view. The smallest size of polar axis length (18.00 μm) was found in T. micranthum Viv. from section Chronosemium Ser.; the largest (88.95 μm) was found in T. hirtum All.

Hypericum turcicum (Hypericaceae) is described and illustrated as a new species from Beypazarı in Ankara Province in Northwest Anatolia, Turkey. The new species belongs to the section Oligostema, and it is closely related to H. aucheri. Diagnostic characters, description, detailed illustrations, ecology, and pollen and seed morphology are presented in this study. In addition, this study evaluates H. kazdaghense, which was previously accepted as a synonym of H. aucheri, as a distinct species and discusses the similarities and differences between H. turcicum and H. aucheri.

Characteristic features of seed and testa cells in 13 species of Allium, representing its five recognized sections, Compactoprason, Megaloprason, Procerallium, Decipientia and Pseudoprason were studied using both stereomicroscope and scanning electron microscope. The identified characters, such as seed shape, alignment and shape of testa cells, features of outer cell walls, verruca type, density of verrucae and granules, seed size as well as cell wall undulations were evaluated statistically. The our findings indicated the significance level of P ≤ 0.

High levels of polyunsaturated fatty acids in chicken spermatozoa make them susceptible to lipoperoxidation and reduce their fertility. This study was conducted to assess the effect of sesame seed suplementation in the diet on the semen quality of Ho cocks. Eighteen 13-14 month-old cocks were randomly divided into three groups and were assigned to one of the following treatments: 0% SS (control), 5% SS, or 7% sesame seeds per kg of diet for ten consecutive weeks after a two-week adaptation period. Semen characteristics were evaluated once a week.
