Rootstocks Influence the Growth, Biochemical Contents and Disease Incidence in Thompson Seedless Grapevines
Year: 2014
Type: article
Abstract: The variations in growth, powdery mildew and anthracnose incidence and biochemical changes in Thompson Seedless grapevines grafted onto Dog Ridge and 110-R rootstocks in comparison to the own rooted grape vines was investigated.Bud sprouting after pruning was achieved earlier in case of own-rooted vines.However, the vine growth pattern studied in terms of the shoot length, inter nodal length, shoot diameter and leaf area was highest in case of vines grafted onto Dog Ridge.Foliar powdery mildew and anthracnose incidence was highest in vines grafted onto Dog Ridge and own-rooted vines, respectively.The disease incidence was recorded least in vines grafted onto 110-R.The biochemical analysis was also influenced by the rootstocks.The leaves of vines grafted onto Dog Ridge recorded the highest reducing sugars and protein contents and the least total sugars and phenolic contents.The vines grafted onto 110-R topped in total phenolic contents and other phenolic derivatives.
