Tolerance to Lime - Induced Chlorosis and Drought in Grapevine Rootstocks - Abiotic Stress: Plant Responses and Applications in Agriculture - page 296

A good understanding of physiological mechanism that enable plants to adapt themselves to
the water deficit and to maintain growth also during stress periods could help within the
framework of individual breeding programs to screen and select stress-tolerant genotypes
(Winter et al ., 1988).

5. Conclusion

Regarding climatic changes and a more and more frequent occurrence of periods of drought
within the growing season, the problem of lime-induced chlorosis and drought damage of
grapevine plants becomes to be more and more important.

Hofäcker (2004) presented a general evaluation of the drought and chlorosis resistance of
rootstocks most commonly grown in Europe; results of this analysis are presented in Table 8.
