To investigate the effect of different types and amounts of jasmines on the quantitative and qualitative characteristics of two strawberry cultivars, a factorial experiment was conducted in a completely randomized design in Sadra Hydroponic Greenhouse of Shiraz University in 2018. Experimental treatments include two types of jasmonate (jasmonic acid and methyl jasmonate) each in five concentrations (0, 0.5, 1, 1.5, and 2 mM) and (0, 0.25, 0.5, 1, and 1.5 mM) with four replications and three pots in each replication and two strawberry cultivars (Selva and Parus). Analysis of variance showed that the effect of experimental treatments on all studied traits except fruit weight and vitamin C was significant. The results showed that foliar application of jasmonate reduced chlorophyll content and leaf dry weight in both strawberry cultivars, while the highest number of fruits in Selva cultivar was obtained by foliar application of 2 mM jasmonic acid. The results also showed that increasing the concentration of jasmonates by reducing the total acidity and increasing fruit anthocyanins in both cultivars, improved the quality properties of strawberries. In general, Selva cultivar is more effective than jasmonate by producing soluble solids and the ratio of soluble solids to total acidity is more significant and the amount of total acidity is lower than Parus cultivar, it is more desirable in terms of quality.
