Vitis vinifera L. is a globally prominent species with socio-economic importance across many
countries, with diverse climates. The leaf blade of grapevines is the most exposed to abiotic
stresses. The study of the leaf blade is particularly important as climate change becomes an
increasingly common theme across the world, greatly affecting agricultural systems. This
review focusses on grapevine leaf morphoanatomy - leaf blade form, mesophyll and leaf
epidermis anatomy, which incorporates the cuticle, indumentum, pavement cells and stomata
- and their adaptation to abiotic stresses. V. vinifera xylem architecture and its adaptation
capacity when the grapevine is subjected to stress is also highlighted since grapevines have
been observed to exhibit a large variability in the way in which they respond to water
availability. The hydraulic properties of the petiole, shoot and trunk were summarised.
Senescence and the metabolic response of the grapevine when under stress were highlighted
as common adaptation strategies. These processes are also part of the grapevine’s recovery
cycle. Short-term strategies were addressed as a way of improving the coping capacity of
cultivars when confronted by climate change. These solutions include the use of kaolin,
irrigation and drought tolerant rootstocks and cultivars. In conclusion, this is a review of recent
advances relating to the adaptation of grapevine morphoanatomical features and hydraulic
architecture to abiotic stresses; heat and water stress, induced primarily by an ever-changing
global climate
