Root hydraulic conductivity in three self-rooted and grafted table grape cultivars

<p style="text-align: justify;"><strong>Aim</strong>: Root hydraulic conductivity is one of the main factors that control water flow in the soil-plant system and ultimately affect crop irrigation requirements. This work sets out to estimate root water conductivity for three self-rooted or grafted table grape cultivars.</p><p style="text-align: justify;"><strong>Methods and results</strong>: We evaluated root water conductivity of the cultivars ‘Black Magic’, ‘Matilde’ and ‘Victoria’ grafted onto 1103 Paulsen rootstock or self-rooted. Measurements were performed on two-year-old table grapes grown in pots filled with pumice. Root water conductivity wa…
