Use of organic acids in micropropagation helps the production of salinity tolerant strawberry

Abstract

Abstract Abiotic stresses cause numerous harms to crops, such as limited growth and reduced yield, salt stress being one of the main culprits. The search for plants that are more tolerant to abiotic stresses is necessary to increase yield. The objective of this study was to investigate whether humic and fulvic acids inserted in vitro promote salt stress tolerance in strawberry plants. Salt stress was induced in plants in vitro, as well as the insertion of humic and fulvic acids. After this process, the plants were taken to the greenhouse and grown under stress to determine the efficiency of the process. The in vitro concentration of NaCl used caused stress in the plants. It was observed that the concentrations of humic acid and fulvic acid influenced the increase in the activity of the plant's antioxidant system in response to the NaCl applied during the growth of seedlings in a greenhouse. Therefore, plants grown in the presence of humic acid or fulvic in vitro acid respond to abiotic stress more quickly, suggesting that humic substances can be used to produce strawberries that are more tolerant to salt stress.
