Drought stress in horticultural plants

Drought stress is one of the main factors limiting horticultural crops, especially in environments such as the Mediterranean basin, which is often characterized by suboptimal water availability. Global changes will determine the increase in semi-arid conditions, so all horticultural crops will have to cope with water scarcity. Appropriate plant selection and new cultivation methods, especially strategies of deficit irrigation, are crucial in improving crop cultivation performance. This Special Issue, entitled “Drought Stress in Horticultural Plants”, comprises 11 innovative publications, which could enrich our knowledge about the mechanisms of plant to drought stress.
