In this paper, we present five species of owlet moths (Noctuidae), whose greater abundance was found in Slovenia in the period 2019-2022 as part of research and expert work in the field of plant protection. The greatest economic importance is attributed to the tomato looper (Chrysodeixis chalcites), which two years after its first strong appearance on the Slovenian coastal area is already causing major problems for tomato growers. We did not confirm the harmfulness of the caterpillars on cultivated plants for the silver-Y moth (Autographa gamma), the adult males of which are caught in large numbers using pheromone traps in central Slovenia, and the less numerous beet armyworm (Spodoptera exigua). We can confirm the same for the shark moth (Cucullia umbratica), whose adult males are caught in pheromone traps of the EU quarantine pest Spodoptera frugiperda and the copper underwing (Amphipyra pyramidea), for which we suggest the Slovenian name ‘bakreni podkrilec’, which appeared in, on or in the immediate vicinity of the pheromone traps of the spongy moth (Lymantria dispar) in the oak-hornbeam forest in Prekmurje.

This study aimed to identify the genetic diversity of date palm (Phoenix dactylifera L.) in the southwest of Algeria (wilaya of Adrar), as part of the Algerian date palm varieties conservation. The morphological characterization was adopted in terms of quality and quantity of 26 varieties. The main results showed a considerable genetic diversity of date palms in this agricultural territory. 7 cultivars counted in danger of extinction. The cluster analysis brought out significant differences between qualitative and quantitative traits. However, the cultivars of ‘Deglet Talmine’, ‘Maatouk’, and ‘Timidouele’ produced dates of high quantitative traits, however, of different qualitative traits. Also, some relationships were observed within clusters for other varieties. A variety named ‘Khalt’ was able to produce dates better than many cultivars. This work would help to know the focal traits of the plant genetic resources of date palm and preserve that are in extinction.
本研究旨在鉴定阿尔及利亚西南部(wilaya of Adrar)枣椰树(Phoenix dactylifera L.)的遗传多样性，作为阿尔及利亚枣椰树品种保护的一部分。对26个品种进行了质量和数量的形态鉴定。主要结果表明，该地区枣椰树具有相当大的遗传多样性。有7个品种濒临灭绝。聚类分析结果显示，质量性状与数量性状差异显著。然而，“Deglet Talmine”、“Maatouk”和“Timidouele”品种生产的枣子数量性状较高，但质量性状不同。此外，在其他品种的簇内也观察到一些关系。一个名为“哈尔特”的品种能够比许多品种生产更好的枣。这项工作将有助于了解枣椰树植物遗传资源的重点性状，保护濒临灭绝的枣椰树植物遗传资源。

The various crises are having a significant impact on the entire food sector and are changing the attitudes of Europeans as well as policies on the importance of food security and sustainably produced quality and safe food for consumer health. The paper focuses on the consumer’s fear of food security for the time of the first wave of COVID-19 and the associated concern for food security in the future and the changes in consumer behaviour. The online survey in Slovenia was conducted in June 2020 using a “snowball” method. The sample included 490 individuals. The results showed that both measured forms of fear (i) fear over food security during the first wave of COVID-19 crisis, and (ii) fear over food security in the future were statistically significant, moderately strong and positively associated with almost all forms of self-perceived behaviour change caused by the COVID-19 crisis. The respondents focused more on buying locally produced and processed food, food stockpiling and decreasing food waste. Only minor changes were expressed with regards to their food purchasing channels, with the elderly, the highly educated and those who classified themselves in a higher social class buying more often directly from farmers. In the future, the results of this research should be compared with other countries and the impact of an individual’s economic situation and the impact of promotional campaigns on agricultural products on changing consumer behaviour should also be analysed in more detail.

To evaluate the genetic diversity of Iranian Narcissus genotypes (e.g., Shomal, Shastpar, Shahla, Yasuj, Shiraz-1, Shiraz-2, Kuchak-e-Atri, Dutch, Khosf-1, Khosf-2, Birjand, and Tabas), different RAPD and ISSR primers were examined at the Plant Breeding Laboratory of the Faculty of Agriculture, University of Birjand, Iran. In sum, RAPD and ISSR primers produced 189 and 80 high-resolution bands. The average values of PIC, Ht, Hs, Nm, DST, FDT, NA, Ne, H, and I indices were 0.287, 0.369, 0.089, 0.486, 0.279, 0.760, 1.952, 1.459, 0.282, 0.437 for RAPD markers and equal to 0.297, 0.380, 0.099, 0.524, 0.278, 0.732, 1.978, 1.495, 0.303, 0.467 for ISSR markers, respectively. The analysis of molecular variance based on the RAPD and ISSR markers showed 23 and 13 % variations for intra-populations and 77 % and 87 % changes for inter-population variabilities, respectively. Cluster analysis based on the RAPD and ISSR markers grouped genotypes into four clusters. Based on RAPD and ISSR markers, the PCoA analysis also showed that the first three components justified equal to 96.9 % and 97.9 % of the total variance, respectively, indicating the dispersion of the primers used. In general, it was concluded that the genetic diversity of narcissus species could be employed for breeding programs.

The fall armyworm (Spodoptera frugiperda) is an invasive and highly destructive insect pest that has caused extensive damage to maize in Africa since its first report on the continent in 2016. Information on fall armyworm infestation and damage within African agroecologies is essential for the development of appropriate pest management strategies, but these are scant in Nigeria. Consequently, in this study, fall armyworm infestation levels and severity of damage to maize in the three major maize-growing agro-ecological zones (humid forest, derived savanna, and southern guinea savanna) of southwestern Nigeria was investigated using standard field sampling protocols. Results showed that maize infestation and damage severity varied across agroecological zones, with the humid forest being the most impacted. Information provided will enhance decision-making for effective management of the fall armyworm in southwestern Nigeria.

Developing biostimulants from salt-tolerant plant growth-promoting (PGP) bacteria is an emerging strategy for sustainable agriculture in the context of increasing soil salinization. This study aimed to isolate endophytic bacteria (EB) capable of promoting rice seed germination and seedling growth at different NaCl concentrations. Nine salt-tolerant EB strains were isolated and two, ST.6 and ST.8, with the rice seed promoting effect 99.3 and 99.7 %, respectively, were selected and identified as Pantoea dispersa and Burkholderia cenocepacia, respectively. ST.6 showed a higher value of the activity of phosphatase (617 mg P ml-1), production of indole-3-acetic acid (19.7 µg IAA ml-1), the activity of 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase (13.5 µmol mg−1 protein h−1), and production of siderophore (76.3 %). Especially, rice seedlings inoculated with strain ST.6 showed a significant improvement in root length (58.95 %), shoot length (16.6 %), dry biomass (7.0 %), the content of chlorophyll (46.2 and 57.1 % for chlorophyll a and b, respectively), carotenoids (22.2%), and proline (19.0 %). A decrease in antioxidant enzyme activities was also observed in the rice seedlings inoculated with either ST.6 or ST.8 strain under salt stress. Furthermore, the salt stress condition enhanced the colonization of roots by both studied endophytic bacteria. More experiments should be done to develop endophytic bacteria ST.6 and ST.8 as efficient bio-inoculants.
从耐盐植物促生长(PGP)细菌中开发生物刺激素是在土壤盐碱化日益严重的背景下可持续农业的一种新兴策略。本研究旨在分离不同NaCl浓度下能促进水稻种子萌发和幼苗生长的内生细菌(EB)。筛选出9株耐盐EB菌株ST.6和ST.8，促种效果分别为99.3%和99.7%，鉴定为分散Pantoea和cenocepacia伯克霍尔德菌。ST.6具有较高的磷酸酶活性(617 mg P ml-1)、吲哚-3-乙酸生成(19.7µg IAA ml-1)、1-氨基环丙烷-1-羧酸(ACC)脱氨酶活性(13.5µmol mg -1 protein h -1)和铁载体生成(76.3%)。其中，接种菌株ST.6的水稻幼苗在根长(58.95%)、茎长(16.6%)、干生物量(7.0%)、叶绿素含量(叶绿素a和b分别为46.2%和57.1%)、类胡萝卜素(22.2%)和脯氨酸(19.0%)方面均有显著提高。在盐胁迫下，接种ST.6或ST.8菌株的水稻幼苗抗氧化酶活性也有所下降。此外，盐胁迫条件增强了两种内生细菌在根上的定殖。将内生细菌ST.6和ST.8开发为高效的生物接种剂还需要进一步的试验。

Introducing grass pea genotypes with wide adaptability across diverse environments is important. Dry forage yield of 16 grass pea genotypes, tested in a RCBD design with three replicates across 4 locations over 3 seasons in Iran. The GGE biplot method based on SREG model facilitated a visual evaluation of the best genotypes. The first two principal components accounted for 77 % of the GE interaction and revealed six winning genotypes and four mega-environments. The average location coordinate (ALC) was used to examine both yield performance and stability and indicated IFLA-1913, IFLA-1961, IFLA-1812, and IFLA-2025 were the best genotypes. Based on the ideal-genotype approach, genotype G5 was better than all other genotypes and showed both high forage yield and stability across locations. According to G + GE sources of variations, the genotypes (IFLA-1913, IFLA-1961, IFLA-1812, and IFLA-2025) were the most suitable varieties for the grass pea-producing regions in semi-arid and rain-fed conditions. An ideal location should be both discriminating of the genotypes and representative of the average location, but we could not find such location in this research. Results confirmed that G5 (IFLA-1961) has high stability and high yield performance (4.92 t ha-1), and could introduce as favorable genotype for commercial variety release.
引入在不同环境中具有广泛适应性的草豆基因型非常重要。16种草豆基因型的干饲料产量，在伊朗3个季节、4个地点、3个重复的RCBD设计中进行测试。基于SREG模型的GGE双标图方法便于对最佳基因型进行直观评价。前两个主要成分占了转基因相互作用的77%，并揭示了6个获胜基因型和4个巨型环境。利用平均位置坐标(ALC)对产量性能和稳定性进行分析，结果表明IFLA-1913、IFLA-1961、IFLA-1812和IFLA-2025是最佳基因型。基于理想基因型方法，G5基因型表现出较高的产草量和跨地稳定性。根据变异的G + GE来源，基因型(IFLA-1913、IFLA-1961、IFLA-1812和IFLA-2025)是半干旱和雨养条件下草豆产区最适宜的品种。一个理想的定位应该是既能区分基因型又能代表平均定位，但我们在本研究中没有找到这样的定位。结果表明，G5 (IFLA-1961)具有高稳定性和高产性能(4.92 t ha-1)，可作为有利基因型引进，作为商品品种投放。

In recent decades, global production of poultry meat has increased due to its affordable prices and good nutritional value. The latter has been achieved by intensive selection of broilers for increased growth rate, feed efficiency, breast yield and reduced abdominal fat deposition. On the other hand, intensive selection and increasing demand for poultry meat, as well as some environmental stressors, such as changes in environmental temperature, feeding regime, breeding technology, and improper handling procedures before slaughter, lead to increased susceptibility of animals to oxidative stress, resulting in poorer sensory and technological characteristics of chicken meat. As a result of intensive broiler production and the increase in breast muscle, various breast muscle abnormalities or myopathies have been observed. The most common ones include deep pectoral myopathy, pale, soft and exudative like meat, white striping, wooden-breast and spaghetti meat, which mainly affect the pectoralis major breast muscle and negatively influence the sensory and technological characteristics of breast meat. The muscle abnormalities have a detrimental effect on quality and nutritional value of meat, affect consumer compromise consumers acceptance, and cause economic losses in the meat processing industry.

On the other hand, intensive selection and increasing demand for poultry meat, as well as some environmental stressors, such as changes in environmental temperature, feeding regime, breeding technology, and improper handling procedures before slaughter, lead to increased susceptibility of animals to oxidative stress, resulting in poorer sensory and technological characteristics of chicken meat. As a result of intensive broiler production and the increase in breast muscle, various breast muscle abnormalities or myopathies have been observed. The most common ones include deep pectoral myopathy, pale, soft and exudative like meat, white striping, wooden-breast and spaghetti meat, which mainly affect the pectoralis major breast muscle and negatively influence the sensory and technological characteristics of breast meat. The muscle abnormalities have a detrimental effect on quality and nutritional value of meat, affect consumer compromise consumers acceptance, and cause economic losses in the meat processing industry.","PeriodicalId":6884,"journal":{"name":"Acta agriculturae Slovenica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91102042","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}
This study aimed to identify the genetic diversity of date palm (Phoenix dactylifera L.) in the southwest of Algeria (wilaya of Adrar), as part of the Algerian date palm varieties conservation. The morphological characterization was adopted in terms of quality and quantity of 26 varieties. The main results showed a considerable genetic diversity of date palms in this agricultural territory. 7 cultivars counted in danger of extinction. The cluster analysis brought out significant differences between qualitative and quantitative traits. However, the cultivars of ‘Deglet Talmine’, ‘Maatouk’, and ‘Timidouele’ produced dates of high quantitative traits, however, of different qualitative traits. Also, some relationships were observed within clusters for other varieties. A variety named ‘Khalt’ was able to produce dates better than many cultivars. This work would help to know the focal traits of the plant genetic resources of date palm and preserve that are in extinction.
本研究旨在鉴定阿尔及利亚西南部(wilaya of Adrar)枣椰树(Phoenix dactylifera L.)的遗传多样性，作为阿尔及利亚枣椰树品种保护的一部分。对26个品种进行了质量和数量的形态鉴定。主要结果表明，该地区枣椰树具有相当大的遗传多样性。有7个品种濒临灭绝。聚类分析结果显示，质量性状与数量性状差异显著。然而，“Deglet Talmine”、“Maatouk”和“Timidouele”品种生产的枣子数量性状较高，但质量性状不同。此外，在其他品种的簇内也观察到一些关系。一个名为“哈尔特”的品种能够比许多品种生产更好的枣。这项工作将有助于了解枣椰树植物遗传资源的重点性状，保护濒临灭绝的枣椰树植物遗传资源。

The cultivation of Rhus coriaria has become necessary to preserve their wild populations. To be competitive in the international market, it is important to develop an efficient production chain to reduce costs and improve the quality of the products. The main objective of this study is to provide a method to determine the suitable areas to develop the R. coriaria cultivation with a case study in Gonabad County of Iran. A habitat suitability model (HSM) was applied to survey the distribution of R. coriaria and to identify the best areas the growing of its. Three different main criteria including environmental suitability, agronomic suitability, and social-economical suitability selected for the HSM. Then, each of the three main criteria and their multi-specific indicator was defined in Analytic Hierarchy Process (AHP) and the weights of them were calculated by pairwise comparison matrix. In the next stage, the weights are applied to their layers such as hypsometry, slope, slope aspect, mean annual precipitation, mean annual temperature, soil texture, landuse, water resource type, water resource quality and quantity, road network, and land ownership as roaster layers. The results of the HSM showed a weighted map of land suitability for the R. coriaria that included the maximum and minimum potential of areas for its planting. Based on these results, the areas with the highest suitability for the R. coriaria are strictly associated with precipitation, soil texture, and water resources type.
