In the last two years (2019-2020) warm winters and very dry\u0000summers have led to the onset of budburst, almost simultaneously for all the studied\u0000cultivars, followed by a very weak growth and development of shoots (2020) and an\u0000acceleration development of phenophases, mainly berween veraison and ripening.\u0000Water stress during the vegetative period, a hygroscopicity below 60% between July\u0000and August and low vegetative apparatus influenced the growth ofthe berries,\u0000resulting small grapes, and a very low must yield in 2020.Concerning the quality of\u0000grape production, the studied cultivars achieved more sugar concentrations in\u0000berries up to 35.8 g/L (in 2019) and 36.0 g/L (in 2020), higher than the values\u0000obtained in normal years.

The current decrease of water resources leads to the\u0000urgent need to adopt a strategy which could be applied to efficiently utilize water\u0000without affecting the growth, yield and fruit quality. Therefore, deficit irrigation is an\u0000alternative. The crop studied was apricot, 'Orizont' cultivar, 13 years old, grafted on\u0000the 'Constanta 14' rootstock. The planting distance was 4 m between the rows and 5\u0000m between trees on the row. The split-plot experiment described here is monofactorial with irrigation strategy having three graduations. The irrigation regime\u0000consists of a fully irrigated treatment (b1, non-stressed) according to the irrigation\u0000needs (100% of ETc = ETo x Kc), a deficit irrigation treatment (b2) irrigated with half\u0000the amount of water in b1 (50% of ETc), and a control, non-irrigated treatment (b3).\u0000These plots comprised three adjacent fruit tree rows, with the central row containing\u0000five trees for measurements and observations. This research aims to study the effects\u0000of deficit irrigation on some quality indicators of apricot fruits after harvest and\u0000storage. Fruits in the b3 treatment were much firmer, followed by the fruits from the\u0000b2 treatment. The study suggests that moderate deficit irrigation can be profitable for\u0000enhancing key fruit quality characteristics.","PeriodicalId":52654,"journal":{"name":"Romanian Journal of Horticulture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49653052","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}
