Tolerance to Lime - Induced Chlorosis and Drought in Grapevine Rootstocks - Abiotic Stress: Plant Responses and Applications in Agriculture - page 287

contributes to the selection of lime-resistant rootstocks. Breeding efforts to get proper geno‐
types included successfully crossing between wild grape species, and some chlorosis-resistant
rootstocks are now available for the grapevine growers of the many calcareous areas world‐
wide (Fregoni, 1980; Pouget, 1980; Bavareso, Fraschini, Perino, 1993). Lime-tolerant grapevine
rootstocks have some specific physiological mechanism to overcome chlorosis when grown
on calcareous soils, including and improvement of root Fe uptake and reducing capacity
(Varanini & Magioni, 1982; Bavaresco, Fregoni, Fraschini, 1991).

Vitis riparia and Vitis rupestris are very important species in the history of the rootstock breeding
activities. These two species are not very tolerant to calcareous soils. Vitis berlandieri is
recognized for adaptation to calcareous soils. Vitis vinifera is species tolerant to calcareous soils
(Cousins, 2005). Knowing the characteristics of the important parental species and rootstock
varieties used in rootstock development helps us to understand the viticultural attributes of
individual rootstocks families.

Data about the tolerance of rootstocks to lime-induced chlorosis, as mentioned by Cousins
(2005) and Chauvet & Reynier (1979) are presented in Table 3.

From the viewpoint of the resistance to chlorosis, the rootstocks registered in the State Variety
Book of the Czech Republic can be ranked from the most resistant to the most sensitive as
follows: Craciunel 2 - SO 4 - Kober 125 AA - Kober 5 BB - Teleki 5 C - Amos - LE-K-1 . These
results are very important from the viewpoint of the use of rootstock varieties for propagation
and growing of grapevine in the Czech Republic (Pavloušek, 2008).

In table 4, the classification of rootstock variety, content of active lime and values of CPI are
described (Juste & Pouget, 1972 In: Huglin & Schneider (1998).
