| Summary: | Under the climatic change scenario, drought is one of the most important constraints to affect crop growth, productivity and quality. Improving crops water stress tolerance is challenging and requires deep research into the plants’ adaptive responses. Phytohormones play an important role in regulating response mechanisms to face drought. In previous studies, the NIBER® pepper rootstock (F1 hybrid) showed tolerance to drought in production and fruit quality terms compared to the ungrafted plants. In this study, the objective was to shed light on drought tolerance strategies by the analysis of the hormonal balance modulation in young, grafted pepper plants under short-term water stress.
