The toxicity Al is one of the major limitations that inhibits the growth and development of plants in acidic soils. In acidic soils (pH <5.0), phytotoxic aluminum (Al3+) rapidly inhibits root growth and subsequently affects the absorption of water and nutrients by plants. Stationary fertilization experiments with wastewater sludge compost treatments to blueberry plants were evaluated. In the spring of 2020, an experiment with increasing doses of compost of 0, 20, 40, 60, 80 t /ha in vegetation pots, under soil water controlled conditions, was organized. Three years after compost fertilization, a 4.2 pH level (strong acid) was experimentally induced in the soil of all vegetation vessels planted with blueberries. The content of phytotoxic forms of aluminum increased with increasing dose of compost, compared to unfertilized control. At the induction of the soil pH of 4.2, in the variant fertilized with the maximum dose of compost (80 t/ha) the mobile and phytotoxic content of Al increased 30 times compared to the same experimental variant from the pre-acidification conditions. In the same time, under the newly created conditions, the mobile phosphorus content in the soil decreased dramatically. In the compost maximum fertilization dose, the mobile phosphorus content from the soil was significantly lower than the unfertilized control.","PeriodicalId":37667,"journal":{"name":"Fruit Growing Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48727657","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}

Therefore, in fruit growing, the aim is to keep the spectrum of weeds below the economic damage threshold (EDT). In this sense, different methods are used: biotechnical (mulching), mechanical (mowing), agrotechnical (black field worked, weeding between rows) or chemical (pre- or post-emergent herbicide use). The paper presents the results of research undertaken between 2019-2021 on the effectiveness of 6 post-emergent herbicides (4 total, based on glyphosate and 2 including other molecules - cycloxidim 100 g / l and oxifluorfen 240 g / l). The application of the products was carried out in an experimental module with the apple varieties 'Jonathan / M9' and 'Idared / M9', 5-7 years old, in variants and replications arranged randomly. Observations and determinations were performed according to the European Weed Research Society (EWRS) scale showed that, from the whole spectrum of weeds followed in the experimental device, the most difficult or difficult to control were the dicotyledonous weeds such as: Equisetum arvense (note 8-9), Cirsium arvense, Gallium aparine, Galinsoga parviflora, Malva neglecta, Matricaria chamomilla, Ranunculus repens, Rumex spp., Stelaria media (note 5).

Integrating the equipment in the technology, it is possible to obtain plant material that will be the basis for the production of mulch, which will be used in the technologies of organic fertilization of fruit/vine plantations. The advantages of this technology are the fact that the fruits obtained will no longer contain chemical compounds, contributing to the preservation of consumers’ health and at the same time the branches or canes resulting from cuttings will be used efficiently. Also, the chopped wood material can be used to make pellets or briquettes, contributing to solving the global problem of harmful emissions into the atmosphere.","PeriodicalId":37667,"journal":{"name":"Fruit Growing Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43190568","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}

C.K.Schneid.) are main traditional fruit tree culture in Romania and represent an economically important fruit species with limited information on its genetic structure. Our objective was to fingerprint 33 cultivars using four Sequence-Related Amplified Polymorphism (SRAP) primer pairs to estimate the genetic relationships among local and international cultivars. The primer pairs amplified a total of 70 alleles ranging from 14 to 21 alleles per marker. A wide range of fragment length was detected among the accessions, from 65 to 2000 bp. The mean number of alleles per primer combination was 17.5, with the most alleles obtained with SRAP80 (21 alleles), range between 65-1800 bp and the fewest alleles (14) were obtained with SRAP95, range between 150-2000 bp. The neighbor-joining dendrogram, based on Rogers genetic distance, of the plum germplasm studied, consisted of two main clusters of different sizes: 23 entries were grouped into cluster 1 and the remaining 10 entries were grouped into cluster 2. It is interesting that cultivars representing plum species with 6x and 2x ploidy levels were clustered together. Another interesting aspect observed refers to plum genotypes clustered closely on the dendrogram according to their pedigree, such as 'Dani' (P14) - 'Tita' (P15), 'Roman' (P7) - 'Early Rivers' (P9), 'Zamfira' (P6) - 'Pescăruș' (P33). Accessions within the Romanian landrace/old autochthonous cultivars group were not clustered together. Regarding the PCA, the first two principal axes accounted for 12.91% (CP1) and 10.46% (CP2) of the total variation, respectively, together explaining 23.37% of the total variability. Our results showed that SRAP markers represent valuable tools for genetic diversity study on Prunus domestica. To our knowledge, this is the first study using SRAP markers for characterization of P. domestica germplasm. In the future, this molecular genetic information can be combined with phenological and biochemical data to identify genes, quantitative trait loci (QTL) and molecular markers that can be used to improve the plum crop breeding program.","PeriodicalId":37667,"journal":{"name":"Fruit Growing Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49472064","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}

A set of 527 apple cultivars from the apple gene bank collected at Research Institute for Fruit Growing (RIFG) Pitești was evaluated for the incidence of scab (on leaves and fruits) and powdery mildew (on leaves and top shoots) in three consecutive years (2018, 2019 and 2020). Phenotypic results were compared to data reported at the evaluation made in 2006. Unfortunately, the incidence of both scab and powdery mildew increased significantly in the last years. In 2021, 48 Romanian apple cultivars were analyzed with molecular markers linked to Rvi2, Rvi4, Rvi5, Rvi6, Rvi8 and Plw. The markers linked to Rvi6 was detected in 31 cultivars. Alleles linked to Plw were expressed from three cultivars. The information on resistance / susceptibility of apple genetic resources towards economically important diseases is important for breeding.
