In watermelon crops in Southeastern Spain, important thermal differences appear during the first stages of plant development that can affect them. This work shows the effect of applying jasmonic acid and benzoic acid (JA+BA), inductors of systemic acquired resistance (SAR) and induced systemic resistance (ISR), respectively, on fruit quality parameters from a crop in a greenhouse in Southeastern Spain, where crops face a remarkable abiotic stress. We assessed two treatments of JA+BA, T1 (500+500 ppm), T2 (2000+2000 ppm) and a control test using an experimental design of randomized blocks with four replications. The results obtained for the parameters assessed (ºBrix, flesh firmness, rind thickness, polar and equatorial diameter) did not show statistically significant differences. The results showed that there was no metabolic cost in the plants when applying the assessed treatments of JA+BA.
