Sažetak
In the context of climatic change, designing plants able to overcome drought is an essential goal. Grafting is an environment-friendly technique to improve water stress tolerance, using “robust” rootstocks. Pepper is a species sensitive, so it is crucial searching tolerant rootstocks. The objective of this study was to evaluate the short-term effects of drought (24h after PEG 5%) on pepper plants grafted using a tolerant rootstock (A25). Plants treatments used were A (scion), A/A (grafted onto itself) and A/A25 (grafted onto A25). After 24 h photosynthesis, water and osmotic potential, nitrate reductase, lipid peroxidation and total radical scavenging were evaluated. A/A25 tolerated better water stress treatment, because could maintain water relations and obtained the less decrease in enzymes capable of reducing reactive species. In conclusion, grafting onto a tolerant rootstock can decrease the negative impact of drought easing the productivity.
