The grafted tomato production must be managed through a profitable capitalization in a fresh state on the local market. Post-harvest temperature and other factors influence the lifespan and quality of tomato fruit. Some researches were carried out on the influence of certain storage conditions on grafted solano-fruit vegetables (eggplant, tomato) in the Horting Institute. The objective of this research has been to establish the influence of rootstock on the behavior in different storage conditions of grafted hybrid ‘Siriana’ obtained in the year 2017 in a Venlo glasscovered greenhouse. The biological material was composed of cultivars of Lycopersicon genus: a scion, ‘Siriana F1’ hybrid and two rootstocks, ‘Buzău’ (Romanian selection) and ‘Emperador F1’ (interspecific Dutch hybrid). The tomatoes have been deposited for 20 days in bulk in plastic crates and stored in hemibiosis (temperature to 25°C) and physioanabiosis (temperature to 7°C and relative humidity to 60%) conditions. The rootstocks have influenced the total losses recorded on tomatoes during storage, did not significantly influence the quality of the fruit, influenced positively the firmness of the tomatoes but do not influence the firmness The results obtained require during the storage period under research conditions. the continuation, respectively the extension of the researches and on other grafted vegetable species and other storage conditions.","PeriodicalId":52654,"journal":{"name":"Romanian Journal of Horticulture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47615636","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}

Oxathiapiprolin, the first member of the piperidinyl thiazole isoxazoline fungicides, was evaluated for efficacy on downy mildew in a field trial conducted in 2021 at the Research and Development Institute for Viticulture and Oenology Valea Calugareasca. Throughout the study, the rate range was narrowed from active ingredient (a.i.) at 200+1600 to 85+85 g a.i. to an optimal effective rate of 20+1000 g a.i./ha. Within that optimal range, the downy mildew incidence treated with oxathiapiprolin and competitive commercially available fungicides was significantly lower than the incidence in the nontreated grapevine with disease pressure. There were no significant differences in the efficacies of product Zorvec (oxathiapiprolin+folpet, co pack) (97,7-98,6%) and the standard fungicide Profiler (fluopicolide+fosetyl-aluminum), (96.9-97.8%). To avoid the development of resistant strains and at the same time to enhance efficacy, in the field, with favorable weather conditions for pathogen growth, two resistance management practices were considered: (I) a preventive foliar application, forecast (to determine the spray timing), with use the fungicides, typically used in IPM, only in tank mixtures or pre-packs; (II) an eradicative foliar application of the systemic fungicides with the purpose off cure existing infections.","PeriodicalId":52654,"journal":{"name":"Romanian Journal of Horticulture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43257099","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}

During conventional growing, the highest mean yields were recorded for ‘Jupânești’ (2.88 t/ha), ‘Valcor’ (2.77 t/ha), ‘Verisval’ (2.58 t/ha), 'Unival' (2.55 t/ha) and in the case of organic production the highest yields were observed for ‘Jupânești’ (3.5 t/ha), ‘Valcor’ (2.95 t/ha), ‘Unival’ (2.67 t/ha), ‘Verisval’ (2.62 t/ha), ‘Valrex’ (2.56 t/ha) and ‘Redval’ (2.54 t/ha). Nuts of these cultivars were subject to measurements regarding fruit size index, index of roundness, nut weight, kernel weight and kernel ratio. The nuts of each cultivar were divided according to class sizes for the international markets. Cultivars with more than 80% of nuts larger than 32 mm were: ‘Valcris’, ‘Sibișel 44’, ‘Valcor’, ‘Germisara’ and ‘Franquette’. The walnut cultivars were evaluated depending on the attack of walnut blight (Xanthomonas arboricola pv. juglandis) and anthracnosis (Gnomonia leptostyla) on leaves and fruits. Walnut blight and anthracnosis attacks were observed on ‘Sibișel 44’, ‘Germisara’, 'Velnița' and ‘Franquette’, while the least affected proved to be: ‘Valcor’, ‘Valcris’, ‘Unival’, ‘Jupânești’ and ‘Verisval’. As consequence, the following walnut cultivars have perspectives to be used for the ecological culture in Romania: ‘Valcor’, ‘Jupânești’, ‘Valrex’, ‘Verisval’, ‘Unival’, ‘Redval’, ‘Velnița’, ‘Timval’, ‘Germisara’, ‘Valcris’ and ‘Franquette’.","PeriodicalId":52654,"journal":{"name":"Romanian Journal of Horticulture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47009076","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}
