Table 5. Evaluation of drought tolerance of individual rootstock varieties (Carbonneau, 1985).
It is well-known that there are really remarkable differences in tolerance to drought. Some
rootstocks (e.g. 101-14 and Schwarzmann) show a low tolerance while in others (e.g. Lider
116-60, Ramsey, 1103 Paulsen, 140 Ruggeri, and Kober 5 BB) this property is better (Sommer,
2009). Also Cirami et al. , (1994) observed a good tolerance to drought in rootstocks Ramsey,
1103 Paulsen, and 140 Ruggeri.
Table 6 presents tolerance to drought in some rootstocks varieties after Lavrenčič et al. (2007)
and Pouget & Delas (1989).
