Leaf removal is a pivotal operation on high-density vines which aims to improve air circulation, light exposure, and leaf gas exchange. The effects of leaf removal (LR) on vine physiology and berry composition in Cabernet Sauvignon grapevines were studied during the 2018\u20132019 growing season in the Bolgheri area, Tuscany, Italy. The basal leaves were removed at fruit set at two severity levels (removal of four basal leaves of each shoot (LR4) and removal of eight basal leaves (LR8)). The two treatments were compared with the not defoliated control (CTRL). The following physiological parameters of vines were measured: leaf gas exchange, leaf water potential, chlorophyll fluorescence and indirect chlorophyll content. The results showed that defoliation increased single leaf photosynthesis. In addition, qualitative grape parameters (phenolic and technological analyses) and daytime and night-time berry temperature were studied. The results showed that leaf removal had an impact on total soluble solids (\u00b0Brix), titratable acidity, and pH. The LR8-treated grapes had higher titratable acidity, while those in the LR4 treatment had higher \u00b0Brix and extractable anthocyanin and polyphenol content. Berry weight was not significantly influenced by the timing and severity of basal defoliation. Therefore, this research aims to investigate the effects of defoliation at the fruit set on vines performance.<\/jats:p>","DOI":"10.3390\/plants10061183","type":"journal-article","created":{"date-parts":[[2021,6,10]],"date-time":"2021-06-10T13:31:39Z","timestamp":1623331899000},"page":"1183","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Effects of Defoliation at Fruit Set on Vine Physiology and Berry Composition in Cabernet Sauvignon Grapevines"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6191-2044","authenticated-orcid":false,"given":"Eleonora","family":"Cataldo","sequence":"first","affiliation":[{"name":"Department of Agriculture, Food, Environment and Forestry (DAGRI), University of Florence, 50019 Sesto Fiorentino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5029-9926","authenticated-orcid":false,"given":"Linda","family":"Salvi","sequence":"additional","affiliation":[{"name":"Department of Agriculture, Food, Environment and Forestry (DAGRI), University of Florence, 50019 Sesto Fiorentino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesca","family":"Paoli","sequence":"additional","affiliation":[{"name":"Department of Agriculture, Food, Environment and Forestry (DAGRI), University of Florence, 50019 Sesto Fiorentino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maddalena","family":"Fucile","sequence":"additional","affiliation":[{"name":"Department of Agriculture, Food, Environment and Forestry (DAGRI), University of Florence, 50019 Sesto Fiorentino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3826-7304","authenticated-orcid":false,"given":"Giovan Battista","family":"Mattii","sequence":"additional","affiliation":[{"name":"Department of Agriculture, Food, Environment and Forestry (DAGRI), University of Florence, 50019 Sesto Fiorentino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1804","DOI":"10.21273\/HORTSCI.45.12.1804","article-title":"Effects of early defoliation on yield, fruit composition, and harvest season cluster rot complex of grapevines","volume":"45","author":"Sabbatini","year":"2010","journal-title":"HortScience"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"292","DOI":"10.5344\/ajev.2008.59.3.292","article-title":"Effect of leaf removal on grape yield, berry composition, and stilbene concentration","volume":"59","author":"Bavaresco","year":"2008","journal-title":"Am.
