Variability of the stomata among 'Albariño' (Vitis vinifera L.) clones and its relationship with susceptibility to downy mildew

In grapevines the stomata are located on the abaxial epidermis of the leaves, arranged in no specific order. As in other plants, they regulate the communication between the internal tissues and the external atmosphere, playing a critical role in both photosynthesis and transpiration processes. Moreo...

As in other plants, they regulate the communication between the internal tissues and the external atmosphere, playing a critical role in both photosynthesis and transpiration processes.

Other authors have examined the differences concerning the number of stomata in different grapevine cultivars (DÜRING 1980, PALLIOTTI et al. 2000, BEN SALEM-FNAYOU et al. 2005), but none had evaluated the differences for this aspect between clones of the same cultivar.
