It is present in every part of the biosphere. Higher plants have small requirements towards Ni for their optimal growth and development. That is why its latent and acute deficiencies in nature rarely occur. Soil and water pollution with Ni is a global issue. This is the reason special attention is paid to the effects of higher Ni concentrations on plants metabolism, their organic production, as well as on the possibility of using plants for phytoremediation of Ni contaminated habitats. Depending on the present concentrations, nickel may favourably, unfavourably or not affect the metabolic processes of plants at all (enzyme activity, photosynthesis, respiration, water regime, mineral nutrition, etc.), and thus the growth and development of plants. There are still many questions about the mechanism of Ni influence on the physiological and biochemical processes of plants. Therefore, we believe the presentation of the previous knowledge about the effect of Ni on plants' life processes can contribute to a better understanding of the biotechnical and ecological significance of Ni, and it can indicate further research directions in this field.","PeriodicalId":31632,"journal":{"name":"Acta Agriculturae Serbica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71194351","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}

However, in organic farming, in order to maintain environmental safety and fulfill consumer demand for pesticide-free food, the control of this disease is a major problem. The use of biocontrol agents with the antagonistic mechanism of control of many phytopathogens is an innovative alternative for cost-effective and eco-friendly production. The antagonistic activities of Trichoderma viride and Bacillus subtilis were tested in vitro against Colletotrichum acutatum, one of major plant pathogens responsible for anthracnose. The microbial antagonists inhibited mycelial growth in the dual culture. T. viride exhibited strong antagonism against C. acutatum isolates (80%). The B. subtilis isolate also had a strong effect on inhibiting the development of C. acutatum (37.5%). The results of this study identified T. viride and B. subtilis as promising biological control agents for further testing against anthracnose disease in fruits.","PeriodicalId":31632,"journal":{"name":"Acta Agriculturae Serbica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71194047","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}

Eight formulations of mayonnaise were obtained with avocado pulp ranging from 51.2 to 70% and sunflower oil ranging from 30 to 48.68%, with all other constituents remaining constant. Sensory evaluation revealed that the mayonnaise made from 55% avocado pulp and 45% sunflower oil was the best when compared to marketed products in terms of sensory evaluation, proximate analysis, microbiological analysis, acid value, and peroxide value. The optimized product was superior in terms of color and overall acceptability than the control sample (P < 0.05). The chemical analysis, i.e., the moisture, fat, protein, ash and carbohydrate contents were found to be 40.54%, 51.1%, 1.22%, 1.71% and 6.23%, respectively, for the optimized product and 26.41%, 66.22%, 0.34%, 1.11% and 6.33%, respectively, for the control sample. Total plate count and yeast and mold count (cfu/g) were found to be 170.3 and 89.33, respectively, for the optimized product and 160.67 and 84, respectively, for the control product. There was an increase in both acid value and peroxide value at all temperatures during storage but a lower increase was found in the sample stored at 25°C. Using the accelerated shelf life technique, the shelf life of optimized mayonnaise like paste based on acid value was found to be 61 days, 41 days and 13 days at 25°C, 40°C and 50°C, respectively. Similarly, the shelf life based on peroxide value was found to be 35 days, 20 days and 12 days at 25°C, 40°C and 50 °C, respectively. Avocado incorporated mayonnaise with acceptable sensory quality and good spreadability can be prepared. Determinations of acid and peroxide values were carried out at regular intervals, ranging from 5 days to 30 days during the storage of mayonnaise. No chemical analysis was done for longer than 30 days, and also no microbiological analysis was performed for the entire storage period; these analyses would be necessary in further research to confirm the shelf life of mayonnaise.","PeriodicalId":31632,"journal":{"name":"Acta Agriculturae Serbica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71194024","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 paper describes the possibility to apply a \"dilute-and-shoot\" method for the determination of tentoxin, alternariol and alternariol monomethyl ether in wheat. The used chromatographic method was liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). The strategy involves extraction the samples with the acetonitrile and water mixture (84/16, v/v), followed by the vortexing, centrifugation and filtration before the injection into the LC-MS/MS system. The recovery was assessed by analysis of spiked samples with a mixture of standard solutions of all three mycotoxins at two spiking levels (0.02 and 0.1 mg kg-1) in six replicates. The obtained average recoveries and precisions (expressed as the RSDr, %) for \"dilute-and-shoot\" method were 76.3% (RSDr of 6.47%) for alternariol, 105.2% (RSDr of 2.16%) for tentoxin, and 86.0% (RSDr of 3.91%) for alternariol monomethyl ether. All the obtained validation data were in accordance with the Commission Decision 2002/657/EC and Commission Regulation (EC) No 401/2006. The main advantages of the present method are the simple and easy sample preparation, along with the high-sensitivity detection.","PeriodicalId":31632,"journal":{"name":"Acta Agriculturae Serbica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71194171","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}

Blood samples were collected from pregnant sheep and preserved at -20°C and further used for evaluating the concentrations of total antioxidant status (TAS), total oxidant status (TOS), malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and paraoxonase (PON-1). In pregnant sheep, TAS, TOS, MDA, SOD, CAT, and PON-1 values were significantly (P < 0.05) different. TOS and MDA increased from non-pregnant ewes to early, mid and late stages of pregnancy whereas TAS, SOD, CAT, and PON-1 significantly (P < 0.05) decreased with the progression of pregnancy. The study suggests that the use of oxidant and antioxidant markers along with the blood metabolic profile should be the recommended procedure for monitoring health status during pregnancy to evade reduced productive performance and economic losses.","PeriodicalId":31632,"journal":{"name":"Acta Agriculturae Serbica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71193767","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 allelic polymorphisms of ACS1 and ACO1 genes, encoding for ACC synthase and ACC oxidase, which catalyse the last two steps in the ethylene biochemical pathway, were analysed in nineteen indigenous apple accessions grown in individual growers' orchards in the regions of central and southwestern Serbia. A polymorphism was detected using the polymerase chain reaction (PCR) for the ACS1 gene and the additional enzymatic digestion of the PCR product with BamH1 and RsaI for the ACO1 gene. The ACS1-1 and ACS1-2 alleles of the ACS1 gene, as well as the a and c alleles of the ACO1 gene were identified. The polymorphisms observed upon PCRs and digestion with restriction enzymes were generated in two genotypes for both genes, i.e. the ACS1 gene - ACS1-1/1 and ACS1-1/2, and the ACO1 gene - aa and ac. Out of nineteen apple accessions, sixteen were homozygous for the allele ACS1-1 and three were heterozygous (ACS1-1/2); regarding the ACO1 genotype, fourteen were homozygous for the allele a and five were heterozygous (ac allelic constitution). The molecular survey in the current study provides an increase in the number of apple accessions with potential to be used as parents in breeding programmes, aiming to obtain high quality cultivars that retain fruit texture during long storage. Therefore, the heterozygous accessions for the ACS1 gene - 'J-LuN/1', 'Kraljica' and 'Šumatovka', may have an important position in future breeding programmes.","PeriodicalId":31632,"journal":{"name":"Acta Agriculturae Serbica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71193854","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 genotypes selected were: genotype G1, originating from the continental part of Croatia (Pitomača); genotypes G2 and G3, originating from the Mediterranean part of Croatia (Kukurini and Posedarje, respectively); and genotype G4, originating from the upland part of Croatia (Gračac). Fruits were harvested at optimum harvest dates in 2010 and 2012. Genotype had a significant effect on each studied pomological trait (length, width, geometric mean diameter, sphericity, volume, surface, shape index, weight, flesh weight, flesh ratio and total dry matter content), while year significantly affected all parameters except sphericity and shape index. The highest values for most pomological traits in 2010 and 2012 were found in the G4 and G3 genotypes, respectively.

Several centuries later, this technique is still used for a wide range of species. However, in order for this measure to be used successfully in production, it is necessary to find a solution for the successful storage of primed seeds. The storage potential of primed soybean seeds was determined by a temperature of 25 °C during the period of 90 days. Soybean seeds were primed with KNO3 (1%), AsA (100 mg L-1) and KCl (1%) solutions, and then stored in natron paper bags, and their quality was tested every 15 days. The results showed that a reduction in the quality of primed seeds was considerably faster than in non-primed seeds. Primed soybean seeds were successfully stored at a temperature of 25 °C for 60 days after priming, and then a significant reduction in their quality occurred. One of the causes of seed quality reduction was an increase in MDA content, especially after 75 and 90 days of storage. Also, free proline concentration was reduced while the content of vitamin C increased after 15 days primarily in seeds primed in AsA and KCl solutions, and decreased after 45 days.","PeriodicalId":31632,"journal":{"name":"Acta Agriculturae Serbica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71193842","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}
