In Sudan, traditional healing practice by herbalists is prevalent among tribes in remote areas that are deprived of modern health care. Barti tribe is a small Arabic speaking community moved from North Darfur state in early dry periods to the Fangoga area in Sennar State. In this study ethnobotanical survey on traditional medicinal plants used by this community was conducted in July 2016. The data was collected from a total of 85 informants with a mean age of 62 years using semi-structured questionnaires. Informants were asked about the plants and the harvested parts they use to cure the prevalent diseases, methods of preparing the herbal remedy, and administrative details. The study documented 53 medicinal plants used to treat various ailments. The most utilized plant families were Leguminosae followed by Apocynaceae and Malvaceae. Based on plant habits, herbs recorded the highest proportion of the medicinal plants (36%) followed by trees (34%) and shrubs (30%). Of the total plants 77% are wild and 23% are cultivated species. Commonly treated diseases are jaundice, rheumatic pain, stomach pain, and snake bites. Further pharmacological and phytochemical research studies are needed to identify active components in the reported plants, and their efficiency to cure the diseases.

: Seed priming is a pre-sowing treatment which enables the seed to germinate more efficiently and improves seedling vigor as well as yield. Hydro-priming is an important seed treatment technique for rapid seed germination and pre-sowing of seeds with halo-priming is also known as an effective tool. Therefore, a study was conducted with the aim of evaluating the effect of different priming sources with various durations on okra seeds germination and development. Two varieties of okra viz. BARI Dheros 2 (V 1 ) and Green finger okra (V 2 ) having four treatments (T 1 , non-primed seeds; T 2 , seed soaking with normal tap water ± 25ºC for 12 hr; T 3 , priming with hot water 50ºC for 5 min; T 4 , priming of seeds with 3% NaCl for 12 hr) were investigated in a completely randomized design (CRD), each treatment being replicated three times. Results of the study showed that maximum seed germination percentage (92.79%), seed vigor index (1019 cm), first flowering days, days to harvesting maturity, 1000 seeds weight, and total number of fruits per plant (29.5) were observed when the seeds primed by hot water 50 º C for 5 min. In this study, seed germination and all other parameters were also increased by normal water and halo-priming (3% NaCl). Our results showed that hydro-priming (with hot water) were found superior to hydro-priming (with normal water) and halo-priming (3% NaCl). Both priming influenced performance of two varieties, though green finger variety showed slightly better performance in almost all the parameters over the variety BARI Dheros 2. Our results suggest that hydro-priming and halo-priming can improve okra seed germination as well as okra production

The use of nanotechnology can fulfill food problems through crop improvement in future time. Nanoparticles can enhance the morphological growth and fruit yield of plants. Titanium is considered beneficial for the growth rate of plants. Titanium dioxide (TiO2) nanoparticles were synthesized by precipitation method. The nanoparticles were carried out at room temperature using TiO2, NaOH and HCl as precursors. Its characterizations were completed by PSA (Particle Size Analyzer), UV-Vis Spectroscopy, XRD (X-Ray Diffraction) recorded result was ranging from 60 to 200 nanometers and crystalline nature and SEM (Scanning Electron Microscopy) of TiO2 nanoparticles. In this research study, we treated Phaseolus vulgaris seeds with five different type 15, 30, 60, 120 and 240 mg l TiO2 nanoparticles concentrations for 1 week (7 days) in the culture tubes and examined morphological such as germination rate and time of seeds, root and shoot growth, height, number of leaves, pods and seeds and biochemical changes. Low concentrations 30 and 60 mg l boost root and shoot growth rate of seedlings and mature plants parameters. The high concentration 240 mg l affected these parameters in a negative manner. At the low concentrations increased height of plants, number of leaves and changed structure and chlorophyll content and weight of seed in treated plants.

The study investigated the germinable soil seed bank along three soil depths in a Tectona grandis plantation (Taungya farm) in Akure forest reserve, Ondo State, Nigeria. Three sampling plots of 50 by 50 m using systematic line transect were laid. Composition of the established plantation was assessed by taking fifteen different soil samples (0–3, 3–6 and 6–9 cm depth) at each plot and the seed banks composition was determined by greenhouse germination over a period of 3 months. In the soil seed bank seedling, the Shannon-Wienner index had 2.8. The result of other biodiversity indices were; 2.8 for species evenness value. For Margaref’s index of species richness, Taungya farm had value of 123.9. Species abundance in seedlings germinated from soil seed bank was observed as 349 species from Taungya farm. On the other hand, sapling densities, the common tree saplings in this plantation were Baphia nitida, Ficus exasperata and Rauvolfia vomitoria. The species abundance from the sapling was also observed in Taungya farm with the total of 27 seedling m.The value in the other biodiversity indices; Margalef’s index of species richness (4.19), Pielou’s species evenness index (0.9) and Shannon Weiner index (2.97). The similarity between the composition of the seed bank flora and that of the above vegetation (sapling) and established plantation was low throughout the study. The seed bank density and diversity for most species in this study were found to be greatly influenced by environmental factors. At low soil depth layer, richness is greater and herbaceous species dominate while at higher soil depth layer (0–9 cm) species richness diminishes and less dominates.

An ethno-ecological study on medicinal and wild edible plants was conducted in Sheka Zone, Southwestern Ethiopia. The objective was to document and analyze the floristic composition and the associated ethnobotanical knowledge of medicinal and wild edible plants. The study applied a combination of standard plant taxonomic, plant ecological and ethnobotanical methods. Ninety five plots of 30 m by 30 m for trees, 10 m by 10 m for shrubs and 5 m by 5 m for herbs were used to collect vegetation data. Four hundred fourteen informants were involved in the ethnobotanical data collection using semi-structured interviews and discussion with informants. Data were analyzed using R Statistical Software version 3.2.3 and analytical methods of ethnobotany. A total of 555 plant species of which 266 (48%) those used as medicinal; 35 (6.31%) wild plants consumed by people were recorded. The plant species recorded indicated high taxonomic diversity as they belong to 341 genera and 115 families. Eight plant community types were identified. In addition to climatic variability, five environmental factors including altitude, slope, aspect grazing, and disturbance had significant contributions in determining plant community types where altitude is the most influential. Fourteen major plant use categories were identified including the medicinal and the wild edibles. The medicinal plants are distributed within the eight plant communities constituting 46% to 72% of their species composition. Of the 35 wild edible plants, 85.71% were also said to be medicinal. Increasing population, commercial agriculture and firewood collection were among the major threats to the vegetation. Plant communities: Ficus-sur-Croton macrostachyus, Schefflera abyssinica-Syzygium guineense, Ilex mitis-Macaranga capensis and Arundinaria alpina-Lepidotrichillia volkensii plant community types constituted more than 65% of their species composition as medicinal, hence, need priority attention for conservation.

A total of 28 tree species were recorded in 0.024 ha in all along with the sampling plots. The higher individual plant density of trees was recorded for Shorea robusta followed by Schima wallichii and Pinus roxburghii.The high IVI exhibited by Shorea robusta is largely due to its higher relative frequency, relative density and relative dominance compared to other species. The occurrence of many species with low IVI values indicates that most species are rarely distributed in the forest. The result of species diversity showed the highest diversity index for trees (2.78) followed by sapling (2.55) and seedling (2.38). The value of species richness in the present study was found to be falling between ranges 15.81 to 37.81. According to girth classes, the tree species Shorea robusta and Tectona grandis followed almost a normal distribution curve with less trees belonging to smaller and big GBH classes suggesting a fairly stable population in the study area. A reverse J-shaped curve for Lagerstroemia parviflora, Schima wallichii, Pinus roxburghii, Terminalia crenata which depicts more of the characteristics of a stable population is found. Quantitative evaluation and analysis of the community structure are important for accurate assessment of biodiversity.

The serious health and environmental problem arises due to arsenic, across the globe. Several researcher have drawn their attention to these problems, arsenic mainly found in soil, aquifer water/drinking water through naturally. In the present study, physicochemical and arsenic content were observed in two types of soil from different agricultural sites of district Ballia, one type of agricultural sites were irrigated by BWDI and other agriculture sites were not BWNDI. Agricultural soil sites (∑N= 209) of BWDI revealed that all soil samples have arsenic content and maximum arsenic concentration (55 ppb) were observed at sites of Basdih, district Ballia, while arsenic content was not detected on the soils of other agricultural field sites (N=∑30) which were based on BWNDI. Interesting and significant observation observed on the surveys based on farmers of the chosen sites, there are no industries or activities found who are able to correlate the high concentration of arsenic in soil except bore well water. Arsenic contents were observed in the 250 bore well water samples and their concentrations were varied with bore well depth. Beyond the 100 feet depth of bore well water showed the maximum concentration of arsenic as compared with 40 feet depth. The high concentration of arsenic, as well as its more retention time, reduces seed viability of radish and carrot plants.

In this study, Hypericum triquetrifolium which grows naturally in western of Turkey (Kazdağ Mount / Edremit Balıkesir) were investigated essential oil content, essential oil composition, diurnal and ontogenetic variabilities. The diurnal and ontogenetic variabilities of the species were first studied. Essential oils in part of the aerial plant raised during flower ontogenesis and achieved the highest level at full flowering and decreased at the fresh fruiting phase. The highest level at full flowering is 0.30% while the lowest level of fresh fruiting is 0.09%. As a result of the study, 27 components were detected from the aboveground parts of H. triquetrifolium at the before flowering, beginning of flowering and full flowering stages. The major components were obtained caryophyllene (32.9%) and caryophyllene oxide (10.8%) at the before the flowering stage, 3-methyl nonane (17.1%) and caryophyllene (14.9%) at the flowering stage and 3-methyl nonane (43.5%) and α-pinene (17.6%) at the fresh fruiting stage.
金丝桃属包括在替代医学和现代医学中用作抑郁和伤口愈合的特别种。本研究以土耳其西部天然生长的金丝桃(Kazdağ Mount / Edremit Balıkesir)为研究对象，对其挥发油含量、挥发油成分、日变化和个体发生变化进行了研究。首先研究了该物种的日变异性和个体发生变异性。部分地生植物的精油含量在花的个体发生期间升高，在完全开花时达到最高水平，在鲜果期下降。盛花期最高为0.30%，鲜果期最低为0.09%。结果表明，在花前、花初和盛花期，三毛三叶草地上部分共检测到27种成分。花期主要成分为石竹烯(32.9%)和石竹烯氧化物(10.8%)，花期主要成分为3-甲基壬烷(17.1%)和石竹烯(14.9%)，鲜果期主要成分为3-甲基壬烷(43.5%)和α-蒎烯(17.6%)。

The present study was undertaken in four major forests (Teak forest, Sal forest, Pine forest and Oak forest) along an altitudinal gradient between altitude 300 m – 2080 m of Kumaun Himalaya. The total density and basal area of trees ranged between 470 ind. ha and 916.67 ind. ha and from 37.82 m ha to 67.41 m ha respectively. Maximum species richness for trees was reported at site KD (17) and minimum at site MG (7). The maximum beta diversity index was recorded for KD forest (5.46) and the minimum was reported for BP forest site (3.12). Regeneration status of forest sites varied from good regeneration to poor or no regeneration. Site MG was found very poor in regeneration. Proportionate distribution of trees, seedlings and saplings showed that site KD contained maximum density of seedlings in comparison with other sites. The minimum density of seedlings was recorded at site MG. This is due to heavy livestock grazing pressure at this site. The results of the study provide baseline data to conserve and recover different forests along the altitudinal gradient and will also help to formulate conservation strategies of forests in Himalaya.
