In this study, which was carried out in Yeşilhisar/Kayseri, it was aimed to determine the heavy metal accumulation in soil, leaves and fruits in apple orchards located on the Kayseri-Niğde highway. In the study carried out in 2021, samples were taken from rows 0, 100 and 200 meters from the highway in orchards at 3 different locations. According to the results of the study, Aluminum (Al), Cadmium (Cd), Cobalt (Co), Chromium (Cr), Nickel (Ni) and Lead (Pd) contents of the samples at 0 meters distance from the road in the orchards were higher than those at 100- and 200-meters distance. A similar trend was observed between samples at 100 meters distance and samples at 200 meters distance. In general, it was determined that Al content was higher in leaf sample, Cr content was higher in fruit sample, and other metals were higher in soil sample. Element contents in fruit sample were listed as Al > Pd > Ni > Co > Cr > Cd. Although fruit sample at 0 meters from the highway accumulate higher heavy metal elements than at other distances, they are still within acceptable limits. The results obtained can give an opinion on the new orchard establishment, especially in the lands close to the highways.
本研究在ye ilhisar/Kayseri进行，旨在测定Kayseri-Niğde高速公路旁苹果园土壤、叶片和果实中的重金属积累。在2021年进行的这项研究中，样本是从距离高速公路0,100和200米的三个不同地点的果园中采集的。研究结果显示，果园中距离道路0米的样品中铝(Al)、镉(Cd)、钴(Co)、铬(Cr)、镍(Ni)和铅(Pd)含量高于距离道路100米和200米的样品。在距离为100米和距离为200米的样品之间观察到类似的趋势。总的来说，叶片样品中Al含量较高，果实样品中Cr含量较高，土壤样品中其他金属含量较高。水果样品中重金属元素含量为Al > Pd > Ni > Co > Cr > Cd，虽然距离公路0 m处水果样品重金属元素积累量高于其他距离，但仍在可接受范围内。所得结果可为新果园的建立提供参考，特别是在靠近公路的土地上。

Thuja occidentalis L. is originated from Eastern North America and it is cultivated in Europe as an ornamental tree. Thuja can be multiplicated generatively and vegetatively, however nurseries are propagating them by vegetative method because in this way the plants inherit the genetics from the mother plants. Furthermore, it is a faster method. Tree highly used Thuja occidentalis varieties: `Europa Gold` (TOE), `Smaragd` (TOS), and `Danica` (TOD) were selected for the research and were subjected to two different propagation periods (May and July). There were selected 5–10 cm, 10–20 cm, and 20–25 cm length stem cuttings. Our data showed different results at the selected varieties: at TOE, the 20–25 cm length cuttings reported a higher rooting at the July propagation period; at TOS were determined that the 10–20 cm cuttings and the May propagation period obtained the highest rooting percentage; in the case of the TOD an increase in rooting percentage was observed at the cuttings propagated in May, moreover the 5–10 cm length. It can be concluded that propagation time and stem cutting length could be an important factor, however is a variety-dependent process.

Enzymes with very important duties, form part of our lives and are useful in various fields. Owing to both the intensity of use and the amount of effective production in standard conditions, the production and use of bacterial-originated enzymes are used continuously in agriculture, health, food and many other industrial areas. Among them, transglutaminases (EC 2.3.2.13) are both intracellular and extracellular enzymes included in the transferase group that catalyse cross-links between proteins. Microbial transglutaminase enzymes are frequently used in the food and pharmaceutical industries to change the functional properties of proteins since it increases viscosity, elasticity and water holding capacity. Particularly the positive effects in meat, dairy, and bakery products such as gelling, increasing mechanical strength, and reducing structural deformations, specifically the texture. It also contributes to reducing the use of additives in diets with low protein and fat content. Furthermore, it reduces the time for cooking processes as well as sensory properties enhancement. Transglutaminase enzymes are also being used in other fields such as tissue culture, biochemical and biomedical research, textile, and leather industries. In this review, a broad perspective is presented on the literature dealing with bacterial transglutaminase studies, especially those belonging to the genus Bacillus. In Bacillus spp., transglutaminase gene was mostly reported in B. subtilis, B. amyloliquefaciens, B. cereus, B. nakamura, B. circulans species and also recently in the whole genome of local Bacillus thuringiensis (Bt) SY49.1 strain (JAHKEZ010000474.1) using the RAST database. It was determined that the Bt transglutaminase gene was 93% identical to that of B. cereus species. The presence of transglutaminase gene in agriculturally indispensable Bt strain can confer them a superficial characteristic due to their water holding capacity in terms of increasing the yield and quality of plant products.

In the study, it was aimed to determine whether the essential oil components (geraniol, carvacrol, citronellol and thymol) and their different concentrations (0, 2, 5, 10 and 20 ml/petri) would cause any allelopathic effects on the germination of wheat seeds. The experiment was carried out in the laboratory environment according to the divided plots experimental design in random plots. The effects of allelochemical species (Carvacrol, Thymol, Geraniol, Citronellol) and their doses were found to be statistically significant (p<0.01) on the germination rate and seedling dry weight of wheat seeds. The effects of allelochemical species (p<0.05) and doses (p<0.01) on seedling fresh weight were found to be statistically significant. As a result, it was determined that some of the herbal allelochemicals used were effective on seed germination and seedling growth in wheat, and the effect ratio increased as the dose increased. It is thought that some essential oil components can be used in the production of bio-herbicides for winter grass weeds, provided that similar studies are carried out on winter crop plants.

Some results regarding the influence of some Solanum rootstocks on eggplant crops from Romania are in this study. Eggplants are popular vegetables all around the world. Among the grafting aims are fruit yield and quality. Eggplant grafting has been a tradition for over 15 years at the Horting Institute from Bucharest. Grafting combinations used have been the S. melongena scions (Aragon F1 from Hazera, Israel and Luiza variety from the Research–Development Institute Vidra, Romania), the S. lycopersicum x S. habrochaites rootstock (Emperador F1 from Rijk Zwaan, Nethelands) and the S. melongena rootstock (L23B eggplant hybrid from germplasm colection of the Research Station Buzău, Romania). By comparing the fruit yield and carbohydrates content of the grafted or non-grafted variants, the grafted eggplants have had outstanding results, values higher than at control eggplants. Production increment has been up to 25.44% (Luiza x Emperador). Carbohydrate content has increased up to 0.14% (Aragon x Emperador). Researches on the identification of some rootstocks compatible with eggplant scions continues in Romania.
本文就罗马尼亚产茄属植物的一些砧木对茄子作物的影响进行了研究。茄子是世界上最受欢迎的蔬菜。嫁接的目的之一是果实的产量和品质。在布加勒斯特的霍廷研究所，茄子嫁接已经有超过15年的传统。所使用的嫁接组合是S. melongena接穗(来自以色列Hazera的Aragon F1和来自罗马尼亚Vidra研究所的Luiza品种)，S. lycopersicum × S. habrochaites砧木(来自荷兰Rijk Zwaan的Emperador F1)和S. melongena砧木(来自罗马尼亚buzuru研究站种质收集的L23B茄子杂交品种)。通过比较嫁接和未嫁接茄子的果实产量和碳水化合物含量，发现嫁接茄子的产量和碳水化合物含量均显著高于对照茄子。产量增量高达25.44% (Luiza x Emperador)。碳水化合物含量增加了0.14%(阿拉贡x皇帝)。罗马尼亚继续进行与茄子接穗配种的一些砧木的鉴定研究。

The Danube river basin collects water from 19 continental European countries, covering an area of 801,463 km2 (according to ICPDR), and making it the most international river basin in the world. Giurgiu Environmental Protection Agency monitors water quality quarterly and the quality of sediment annually, taken from the sectors corresponding to kilometers 502, 511 and 520. The research in this paper is part of this monitoring program. The present work "Studies on the quality of the Danube in Giurgiu area", aims to achieve the following objectives: Determining the structure of phytoplankton biocenosis; Determining the dynamics of the seasonal variation of the physical-chemical parameters in the studied period; Correlation of the variation dynamics of phytoplankton density with the main physical-chemical parameters; Determining the ecological status of water quality in the studied sector. Both sampling areas are characterized by a good ecological status - the values of biological, hydro-morphological and physical-chemical elements have moderate deviations from the values characteristic of unaltered (reference) areas or minor anthropogenic alterations. In the future, it is recommended to monitor the Danube River in order to prevent possible sources of negative anthropogenic impact and to monitor it with an annual frequency in order to make sure that the ecological quality status is maintained at least at the current level.

Soil salinity is one of the major problems in agriculture, most saline soils are found in arid and semiarid regions. As in other plant species, soil salinity also affects melon production. It is important to use tolerant varieties to be least affected by soil salinity. In present study, two local Turkish cultivar and three their crossed population (Semame, Uzbek, SemamexAnanas, AnanasxSemame and MidyatxAnanas) were tested under in vitro and pot experiments using different NaCI conditions(0, 100,150 and 200 mM). The results have shown that selection for salt tolerance high salt concentration (150 mMol) has negative significant effect on melon performance. Among the five tested cultivars, Midyat x Ananas and Uzbek showed more tolerance compared to other cultivars. In greenhouse, plant heigh, stem diameter and leaf length of Midyat x Ananas had their highest value at 100, 150 and 200 mM, respectively. Meanwhile, best performances of Uzbek for plant height, root dry matter content, root length, leaf length and diameter were obtained at 100 mM. Except for MidyatxAnanas, increase in salt concentration had less impact on plant growth. There was more correlation among morphological and physiological variable in greenhouse experiment compared to in-vitro experiment, therefore it is advised to select melon plants once they start flowering or at least after three months as it has been demonstrated in this experiment.
土壤盐碱化是农业的主要问题之一，大部分盐碱化土壤分布在干旱和半干旱地区。和其他植物种类一样，土壤盐分也影响甜瓜的生产。重要的是选用耐盐品种，使其受土壤盐分的影响最小。以2个土耳其本地栽培品种和3个杂交群体(Semame、Uzbek、SemamexAnanas、AnanasxSemame和MidyatxAnanas)为研究对象，在不同nacl浓度条件(0、100、150和200 mM)下进行了离体和盆栽试验。结果表明，高盐浓度(150 mMol)选育对甜瓜生产性能有显著负向影响。在5个受试品种中，Midyat x Ananas和Uzbek表现出较强的耐受性。温室条件下，冬青株高、茎粗和叶长分别在100、150和200 mM处达到最大值。同时，乌孜别克在100 mM处株高、根干物质含量、根长、叶长和直径表现最佳。除乌孜别克外，盐浓度的增加对植株生长影响较小。与体外栽培相比，温室栽培中形态和生理变量之间的相关性更强，因此建议在甜瓜植株开始开花后或至少在三个月后进行选择，正如本试验所证明的那样。

Non-timber forest products have a lot of other terms which are more or less synonyms like „natural products, wild products”. Non-timber forest products (NTFP) represent a category of products which are provide of wild plants and animals from the forest or from any other natural vegetation types. Around the world humans harvested NTFP from the oldest time. The most common types of NTFP at global level are forest fruits, medicinal plants, fauna of hunting interest and edible mushrooms. Romania has a high potential regarding the harvesting of these types of products due to big diversity of forest and forest site conditions. The aim of this study was to highlight the most important non-timber products from Alba county. First of all was made a selection of most common non-timber products and then were realized a ranking using a set of 19 criteria. The study conclusion was that the most important NTFP from Alba county are honey and hazelnuts follow by golden Chanterelles (Cantharellus cibarius) and Christmas tree.

As part of an approach for selecting potential mycoinsecticides for biocontrol control of weevils, the physiological properties of the strains are to be considered. The paper aimed to investigate the temperature effects on the vegetative growth, conidia germination, and viability of the fungal strains Beauveria bassiana CNMN-FE-01. As a result of the provided analyses, it was shown that the radial growth of the investigated strain follows a linear model. Based on the rate of average radial growth data, the optimum temperature growth at 25°C was determined, while at 35°C, the growth stops. Furthermore, it was found that the maximum rate of sporulation and germination of B. bassiana strain CNMN-FE-01 are at 25°C. At this temperature, the strain maintains the viability of the spores in a proportion of 86% for 90 days. However, temperatures above 25°C significantly reduce the viability of spores. The inhibition in growth of the investigated strain Beauveria bassiana CNMN-FE-01 at 30°C and higher and considerable reduction of its spore viability after extended exposure to 30°C testify to the need for repeated application when used as a biological control agent.

In recent years, with the effect of the climate change, drought is accepted as one of the most important natural disasters. In the planning, development and management processes of water resources, studies on the analysis of past droughts and the decreasing of possible negative effects in the future, have become even more substantial. The best adaptation to drought risk can only be achieved by adopting holistic approaches. In this study, Dörtyol-Erzin Plain, which is located in the south of Turkey and covers the fertile agricultural lands of the Asi River Basin with a drainage area of approximately 7800 km2, was preferred as the case study for hydrological drought analysis. In the literature, it is stated that there is a slow drought progress for the Asi River Basin. It is highlighted that decreasing trend in groundwater and increasing trend in evaporation and temperature parameters are remarked. Since the agricultural irrigation of Dörtyol-Erzin Plain is dependent on groundwater and surface resources, hydrological drought analysis over the long period will be beneficial for the future studies. Accordingly, Streamflow Drought Index (SDI) method was used for the hydrological drought analysis by using 35 years of flow data between the years of 1986-2020. The open source “SPI_SL_6.exe” program via National Drought Mitigation Center (NDMC) was operated in the calculations. Drought results were analyzed at different time scales of 3, 6, 12, 24 and 48 months, afterwards relevant graphs and tables were created. Consequently, the longest dry period has been determined between 2008 and 2012 water years, while the wet period has been evaluated between 2003 and 2007 ones. Furthermore, it is concluded that SDI values decreased as the monthly time periods increased, while the maximum indice values were obtained with SDI-3 in all drought periods. When all graphs are examined detailed, it can be expressed long-term droughts for certain water years are notable.
