Almond is a type of fruit that grows both economically and naturally in many regions of Turkey. In this study, leaf and fruit characteristics of 3 different almond varieties of foreign origin grown in Ürgüp district of Nevşehir province in the Cappadocia region in 2021 and 2022 were determined. Ferragnes variety with a value of 23.47 mm in terms of leaf width, Ferragnes variety with a value of 67.9 mm in leaf length, and Ferraduel variety with a value of 13.62 in terms of petiole length formed the highest values in the leaf characteristics examined. Considering the fruit data, it was determined that Ferragnes variety had the highest value in terms of fruit length with 40.62 mm, Ferragnes variety had the highest value in fruit width values with 23.99 mm, and Ferragnes variety had the highest value in terms of fruit weight with 6.24 g. When the kernel weight data were examined, the highest value was found in Ferragnes variety with 1.61 g, and when the kernel width and kernel length data were examined, the highest values were determined in Ferragnes variety with 14.55 mm and 27.70 mm, respectively. The results of the study are thought to be important in terms of shedding light on future studies, especially since limited studies have been carried out in this region.

This study was carried out to determine the performance of 6 different day-neutral varieties (Albion, Monterey, Portola, Sweet Ann, Kabarla and San Andreas) and 1 local genotype in open field in the ecological conditions of Yahyalı (Kayseri/Türkiye) in the 2021-2022 growing season. In the research, the first flowering date of the varieties was 19 March (local genotype) and 27 March (Portola), the harvest start date was 19 May (Kabarla) and 25 May (Albion), the end of harvest date was August 17 (local genotype) and 20 September (San Andreas). The harvest period was determined between 87 days (local genotype) and 122 days (Kabarla). In the experiment, the highest fruit weight and fruit firmness were determined in Sweet Ann variety with 11.74 g and 0.75 kg-force, respectively. It was determined that the total soluble solid (TSS) content amount in the cultivars varied between 6.16% (Sweet Ann) - 13.16 (local genotype), titratable acid content ranged between 0.48% (Sweet Ann) - 0.77 (San Andreas), pH value varied between 3.23 (San Andreas) - 4.03 (local genotype). While the highest lightness (L) fruits were obtained from Portola variety (31.09) in the experiment, the color intensity (chroma) varied between 31.22 (Albion) and 40.75 (Portola), the color angle value (hº) ranged between 38.61 (Albion) and 50.34 (Monterey and Portola). As a result, in Yahyalı (Kayseri) ecological conditions, in terms of yield and fruit quality characteristics such as fruit weight, color, firmness and TSS amount, Albion variety was found to be suitable, and then Sweet Ann and Kabarla varieties were important.

The study focused on germination parameters as the most critical stage of plant development in dry bean cultivars under different salt treatment. For two used cultivars (Akman-98, Karaman-2016) the data on germination percentage, mean germination time, seedling shoot length, seedling root length, seedling length and seedling vigor indexes were reached under the different salinity levels of irrigation water (0 mM, 25 mM, 50 mM, 100 mM, 150 mM, and 200 mM of NaCl) in Petri plates. The data indicates that these parameters could be used as screening the dry bean cultivars against salt stress levels. This study was carried out in a Completely Randomized Design (CRD) with a total of 12 treatments (6 salinity x 2 cultivars) for the germination and seedling data each comprising of three replicates. The results demonstrated that; i) From the overall observation of the germination characters, at 100 mM and over salt treatments showed decreasing in the germination percentage, the seedling length and the seedling vigor index in the mean of the cultivars, ii) Significantly decreasing in the seedling shoot length were observed in the mean of the cultivars at just after 25 mM and gradually at all salt concentrations, iii) Although the root length showed increasing in 25 and 50 mM treatments than the control plants, a sudden decrease occurred after 100 mM salt treatment in the mean of the cultivars and in each cultivars separately, iv) The mean germination time were sharply in increasing starting with 25 mM treatment in the mean of the cultivars, v) Except the seedling shoot length, in the mean of all the salt treatments between the cultivars did not show statistically differences in the calculated parameters, vi) Any correlation was found between the salt concentrations and the cultivars.

By using biofertilizers consisting of beneficial microorganisms instead of synthetic chemicals, plant growth is increased, damage to the environment is largely prevented and soil fertility is preserved. This study was conducted using seven standard cultivars (Scarlet Spur, Red Chief, Fuji, Jeromine, Galaxy Gala, Granny Smith, and Golden Reinders), which were budded onto M9 and MM106 rootstocks commonly used in the region. During the experiment, nitrogen and phosphorus solvent rhizobacteria were applied three times over a 15-day period in the spring. The application of rhizobacteria had a positive impact on the catalase (CAT), superoxide dismutase (SOD), and peroxidase (POD) activities observed in the leaves across all scion-rootstock combinations. This effect ranged from 4.0% to 30.0% for CAT, from 5.2% to 21.7% for SOD, and from 13.7% to 29.1% for POD. In this study, very significant results were obtained on the effects of rootstocks and rhizobacteria application on enzymatic activity. The results of the present study may provide significant leads for further studies on this subject.

Since ancient times, plants were used for different purposes: even we talk about medicine, construction materials, food or feed. In modern times, plants are a huge factory of compounds which can replace synthesis and hazardous compounds, being appreciated like raw materials in different fields. In the field of cultural heritage protection there is an urgent need to develop innovative, eco-sustainable, and safe solutions, so, plants’ constituents can be an excellent choice. In this context, our short review intends to present a critical opinion on aspects regarding obtaining methods of plants extract, some aspects regarding chemical active compounds, and their application in the cultural heritage domain, being a starting step for a future trans disciplinary study, which offers links between multy disciplinary sciences: chemistry, biology, restoration and conservation.

The relationship between humans and nature is in a constant state of transformation. Humans interpret nature differently, but the undeniable need for a connection with natural areas persists. The value of natural soundscapes in overcrowded and noise-polluted cities is often overlooked. The current survey and conceptual plan aim to develop proposals for the use of the Homorodlok area, taking into account its unique natural characteristics and sounds, as well as the needs of the local population. An important aspect is to showcase the mountainous landscape, highlighting its values while also presenting the impact of human activity on nature. Homorodlok is located in the northern part of Căpâlnița settlement, in Harghita county, Romania, and covers an area of 3.82 hectares. Locals use the area for various events. The diversity of land use in the outskirts of this settlement creates opportunities in some places and problems in others, making it essential to adapt the area for everyday life. The proposal aims to resolve the rural public space of Căpâlnița and strengthen the area's connection with the settlement by developing a plan that considers natural components, including changes in land use, alongside people-centered perspectives.

The objective of this study is to identify and characterize the different types of livestock systems in the region of Sfissifa, wilaya of Nâama (Western Algeria). To this end, 50 livestock farmers were surveyed in this region, and the results of the field investigations revealed three main categories of livestock farmers: semi-sedentary to sedentary livestock farmers, small sedentary livestock farmers, and large livestock farmers. The livestock farmers surveyed had acquired at least one level of education thanks to the reforms undertaken by the public authorities in terms of rural development, at a time when livestock farming was no longer the preserve of illiterate people. 42% of the farmers surveyed are between 51 and 67 years old, and the animals raised are of the Ouled Djellal and Rembi breeds, in view of their hardiness and productive potential in terms of growth. The viability of any breeding system depends on the conciliation between its three poles: the breeder needs the ewe, and the ewe needs the food provided by the environment.

In the assortment of cut flowers, carnations (Dianthus caryophyllus L.) fall in the first places, with a large number of varieties, of various colors, being appreciated on the cut flowers market. Carnations flowers that cannot be sold immediately after harvest, being a time of year when the market offers an abundance of cut flower species, they are prone to rapid depreciation under normal environmental conditions. Carnation is an important ornamental plant, which is used as a potted plant as well as a cut flower. One factor that influences the shelf life is temperature. From the flowering stage to the total depreciation of the inflorescence, it plays an important role. In this experiment, the flowers were harvested on two different dates for about a month. The temperatures at which the varieties were kept had 6 graduations (from 10 to 22 °C). The parameters followed were: bud height, corolla height above the calyx, bud diameter and flower stem length. Storing flowers in water at 4 °C for 6 to 15 days, did not increase the diameter of the flower bud. In flowers kept at 22 °C for 6 days, the values of several parameters of cell senescence fell below the values of fresh flowers. However, in flowers kept at 4 °C there was no expected slow decrease in these parameters, but rather an increase above the levels found in fresh flowers. We conclude that storage at low temperatures has effects on carnation cut flowers, other than slowing down the aging process.

A comprehensive analysis of alien flora from Dâmbovița county (Romania) was performed both on data from literature and personal observations in the field. The assessment of alien flora was focused on taxonomy, species origin, way of introduction, invasiveness status, introduction period, lifespan, bioforms, characteristic habitats and population size. There were identified 187 alien species of which 70 taxa are invasive and potentially invasive. A number of 138 species have been introduced intentionally in the area of Dâmbovița county, most of them being neophytes. There were identified some hotspots where 11 alien taxa have a high density, as follows: Ambrosia artemisiifolia, Sorghum halepense, Amaranthus retroflexus, Erigeron canadensis, Xanthium orientale subsp. italicum, Reynoutria x bohemica, Solidago canadensis, Reynoutria japonica, Erigeron annuus subsp. annuus, Robinia pseudoacacia, Eriochloa villosa. The largest populations of alien species were recorded in natural and anthropogenic habitats such as: railway embankments, roadsides, vacant lands, abandoned arable lands, wastelands, croplands, riparian habitats and degraded grasslands.

The assessment of alien flora was focused on taxonomy, species origin, way of introduction, invasiveness status, introduction period, lifespan, bioforms, characteristic habitats and population size. There were identified 187 alien species of which 70 taxa are invasive and potentially invasive. A number of 138 species have been introduced intentionally in the area of Dâmbovița county, most of them being neophytes. There were identified some hotspots where 11 alien taxa have a high density, as follows: Ambrosia artemisiifolia, Sorghum halepense, Amaranthus retroflexus, Erigeron canadensis, Xanthium orientale subsp. italicum, Reynoutria x bohemica, Solidago canadensis, Reynoutria japonica, Erigeron annuus subsp. annuus, Robinia pseudoacacia, Eriochloa villosa. The largest populations of alien species were recorded in natural and anthropogenic habitats such as: railway embankments, roadsides, vacant lands, abandoned arable lands, wastelands, croplands, riparian habitats and degraded grasslands. The information regarding the habitats, size of populations and spreading of alien species are useful in order to take specific measures for their control.","PeriodicalId":254664,"journal":{"name":"Current Trends in Natural Sciences","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114649580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of microalgae in biotechnological processes, such as bioenergy production and wastewater treatment have been and continue to be of great interest. However, the commercialization of their potential is hindered due to various technical challenges, with biomass harvesting being the largest and most expensive energy consumer among them. Therefore, a major challenge is in finding an efficient harvesting method with high economic feasibility. In this study, a rapid-sedimentation freshwater green microalga was used for batch treatment of artificial wastewater. This strain, in addition to its ability to efficiently remove and use N, P as a source of nutrients, has the advantage of a fast-sedimentation innate feature that allows for a rapid biomass settling (less than 10 minutes) without the addition of any flocculant. This green microalgal strain grows in the form of macrocolonies that significantly favor harvesting by rapid natural gravitational sedimentation. Thus, as this microalga will not require centrifugal harvesting, which is expensive and energy-consuming, its use at both bench and pilot scale could be a promising, cost-effective, and environmentally friendly approach for biotechnological applications.
