Physiological mechanisms used by grapevine varieties to cope with water deficit

Abstract

Historically grapevines have originated from different environments and have evolved a range of physiological strategies to deal with abiotic stress. However, current irrigation practices do not always take into account the different responses that grapevine varieties display towards water deficit. In the semi-arid Murray- Darling region of Australia, irrigation is vital for grapevine growth, but experience with irrigating in this environment has shown that there may be an advantage in tailoring irrigation management strategies to take into account differences between cultivars in their responses to water deficits. Recent research has indicated the potential for categorising varieties based ..
