Abstract
Drought is currently the riskiest abiotic stress affecting the agricultural sector.
Every year, the proper food supply is compromised due to this problem.
The most important challenge of modern agriculture is to satisfy food needs while ensuring environmental safety.
To optimize water use, soilless cultivation has become one of the most popular farming systems in recent years.
Our trial provides data concerning the organoleptic and nutritional qualities of strawberry fruits (Fragaria × ananassa Duch.) obtained from plants cultivated in pots, under different water supplies.
Three strawberry genotypes developed by the UNIVPM breeding program were tested.
Three randomized blocks of 27 plants were differently irrigated: the control WW (about pF1 of the substrate’s water holding capacity), the first stress WS1 (among pF 1-1.7), and the second stress WS2 (about pF 1.7-2). The results highlight the possibility of reducing irrigation amounts without affecting strawberry yield or the content of healthy compounds in the fruit.
Specifically, folic acid, anthocyanins, polyphenols, antioxidant capacity, ascorbic acid, and phenolic acids were analyzed using spectrophotometry and high-performance liquid chromatography.
This confirms the higher resilience of the new genetic material obtained by the UNIVPM breeding program.
