This study aimed to develop a rapid clonal propagation protocol using in vitro methodologies. The ironwort seeds were pre-treated with three concentrations of GA3 (250, 500, and 1000 mg l-1). During the inoculation stage, two types of culture media, Murashige & Skoog (MS) and Woody Plant Medium (WPM), were tested, and the effects of both GA3 concentration and culture media used were evaluated. For the subculture stage, three cytokinins (6-benzylaminopurine / BAP, kinetin, zeatin) at four concentrations (0.5; 1.0; 1.5; 2.0 mg l-1), were compared for the RGR index, while for the rooting stage, two different auxins (1-naphthaleneacetic acid / NAA and indole-3-butyric acid / IBA) at four concentrations (0.5; 1.0; 1.5; 2.0 mg l-1) were tested. GA3 at 500 mg l-1 and MS medium resulted as more effective. The highest value of the RGR index during the subculture stage was obtained in the MS nutrient medium supplemented with BAP at 1.5 mg l-1. For rhizogenesis response, IBA was more effective for roots and length number. Based on these results, in vitro methodologies can be a promising tool for the mass production of this endangered plant species and with possible applications for enhancing the production of valuable nutraceuticals.","PeriodicalId":6884,"journal":{"name":"Acta agriculturae Slovenica","volume":"56 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89145516","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}

Eleven genotypes of mango various cultivars were examined for variability, heritability, and genetic advance, as well as multivariate analysis based on cluster and principal component analysis (PCA) for yield and some of its contributing traits during the two growing seasons, 2021 and 2022. All studied traits showed significant differences, and the phenotypic coefficients of variation (PCV) were found to be higher than genotypic coefficients of variation (GCV), supporting the idea that morphological (genetic) traits are more prevalent than environmental influence. All traits had substantial heritability ranging from 75.63 to 99.93 %, and the highest significant genetic advance (119.09 %) was for the number of fruits per tree than other traits. Four clusters were formed, i.e., clusters I and IV had four genotypes, cluster II had two, and cluster III had one genotype. The highest cluster mean values for fruit diameter, fruit mass, yield per tree, and the number of fruits per tree were found in Cluster II, followed by cluster I. Greater genetic divergence was found between ‘Zebda’ or ‘S9’ or ‘S10’ with most other genotypes, indicating that these genotypes may be used to study the characters’ broad range of variability and to yield high-quality recombinant lines. In light of the fact that mango is a very heterozygous crop, our current genetic results can be used for the selection of the appropriate parents in hybridization programs and in vegetative propagation to yield selective traits.","PeriodicalId":6884,"journal":{"name":"Acta agriculturae Slovenica","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81081046","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}

In this context, we are interested in peroxidase (POD), an important enzyme in plant physiology but whose activity seems to be conditioned by the presence of insecticides in the soil. This work aims to study the impact of locally used insecticides (chlorpyrifos and dimethoate) on the activity of POD in parsley, onion, celery and garlic grown in soils treated or not. POD extraction was performed using Tris-HCl buffer (pH 7.3); its activity was measured using the substrate o-dianisidine in the presence of H2O2. Our result showed that POD activity for insecticide treated parsley, celery and onions increased by 30 % 127 % and 341 % respectively, however did not change significantly for garlic. Thus, the action of these chemicals is not trivial because they may alter non-target pathways, especially when doses are not adjusted accordingly. We found that insecticide stress would increase POD activity in all vegetables except garlic, which showed tolerance to insecticides. Our findings suggest that organic farming conditions could minimize peroxidase activity in parsley, celery and onion. We add that overproduction of POD negatively affects the quality and reduces the shelf life of vegetables, thus would be a very interesting biomarker of insecticide stress.","PeriodicalId":6884,"journal":{"name":"Acta agriculturae Slovenica","volume":"49 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86179024","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}

It has been established that the intensive dissemination of the species of the quarantine ragweed weed occurs both naturally and anthropically. Monitoring of the dissemination and growth of ragweed species is noted in all types of phytocenoses of the steppe. The increase in the areas of dissemination of aggressive species of ragweed weeds poses a widespread threat to all plant populations. Studies show a tendency to increase the number of ragweed plants in such plant groups as agrophytocenoses, phytocenoses of planted forests, phytocenoses of urban areas, meadows and pastures. For the period 2011-2002 the number of ragweed plants increased in meadows by 7.5 times, in pastures by 14.8 times, in agrophytocenoses by 2.95 times, in phytocenoses of urban areas by 1.68 times, in phytocenoses of planted forests by 1.28 times. Due to the lack of control over the dissemination and appropriate eradication measures, the largest increase in the number of ragweed plants over the past 10 years has been observed in meadows and pastures. It is recommended in phytocenoses of planted forests and urban areas in meadows and pastures, total mowing of ragweed plants before their flowering 5-7 times during the growing season in order to prevent replenishment of the seed stock of this weed in the soil during the growing season.","PeriodicalId":6884,"journal":{"name":"Acta agriculturae Slovenica","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81495844","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}

Severe drought stress had a significant effect on plant height. Plant height reduced 31.8 % after using 50 % of PWR compared to the control conditions. Although drought stress negatively affected the 1000 seed mass and seed yield, GABA foliar application alleviated these effects. After using 50 % of PWR, 10 mg l-1 of GABA increased the seed yield and harvest index up to 21.22 and 15.5 %, respectively, compared to the non-foliar application. The reduction in PWR from 100 to 50 % led to increasing in P and K concentrations, as well as sugar and proline contents. In the same conditions, the use of GABA or V had a significant effect on improving these traits. A similar trend was also recorded in relation to water use efficiency.

Two field experiments were conducted during 2017-2018 and 2018-2019. Three cropping regimes (monocropped wheat, monocropped faba bean, and intercropped wheat-faba bean) and three nitrogen levels N0 (0 kg N ha-1), N1 (50 kg N ha-1), and N2 (100 kg N ha-1) were evaluated. Compared with monocropping, intercropping (N0 level) reduced the incidence of stripe rust by 71–120 % and severity by 244–337 % in 1st and 2nd experiments respectively. In addition, the incidence of septoria was reduced by 236 % and severity by 276 %. Obviously, the intercrops significantly decreased the total weed biomass by more than 40 % in both experiments. Black aphid populations in faba bean were reduced by 80 %. In contrast, the nitrogen fertilizer increased the attack of diseases and black aphids. It is concluded that wheat-faba bean intercrops can be used as a method of reduction of inputs, reduction of environmental impacts of crops, and stability in the face of biotic factors.","PeriodicalId":6884,"journal":{"name":"Acta agriculturae Slovenica","volume":"57 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81627663","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}
