Temperature and drought are the most important factors that limit the distributions of many crops. Olive tree (Olea europaea L.) is mainly growing in the Mediterranean where prolonged droughts may occur during the vegetative period. This species has developed a physiological mechanisms to tolerate drought and resist low temperatures. We evaluated sensitivity to low temperatures and resistance to drought in 5 varieties of olive during summer and winter in the Patagonian steppe (45º 47?S, 67º 30?W).
