Abstract
Vitis vinifera L. vines can be protected from the pests such as phylloxera and nematodes by grafting onto resistant rootstocks.
Grapevine rootstocks may have different absorption capability or tendency for some specific minerals.
High Pb, Cu, Zn and Cd concentrations may easily impair plant growth and development.
Cadmium (Cd) is one of the toxic heavy metals with great impacts on environment, plant and human health.
In this study, response of 12 grapevine rootstocks (5BB, 8B, SO4, 420A, 99R, 110R, 140Ru, 1103P, 1045P, Dogridge, Harmony and 41B) and grafted grapevine (Narince/41B) saplings to Cd toxicity were investigated.
CdSO4 was applied at the rates of 0, 5, 10 and 20 mg kg-1 to in a single dose to represent different Cd toxicity levels in soils.
Leaf mineral (Cd, N, P, K, Cu, Mn, Fe and Zn) concentrations were determined to see the effects of Cd treatments on mineral uptake of the plants.
Among the investigated rootstocks, 8B (2.20 mg kg-1 Cd) and 1103P (2.17 mg kg-1 Cd) transported the greatest quantities and the rootstocks SO4 (0.53 mg kg-1 Cd) and 1045P (0.69 mg kg-1 Cd) transported the least quantities of Cd to the leaves at Cd 20 treatments.
Present findings revealed that some rootstocks (1045P, SO4, 99R, 110R, Dogridge) transported less quantities of Cd to the leaves than the others under Cd toxicity conditions.
Such a case indicated genetic differences between the rootstocks with regard to Cd transport.
