Abstract: 

Peach has high nutritional values that can be used either fresh or processed. Thus, in this study, the effect of different levels of methyl jasmonate (0, 100 and 200mgL-1) and salicylic acid (0, 1 and 2mM), and their interactions on increasing qualitative and antioxidant characteristics at harvest time of “Elberta” peach were investigated. In doing so, trees sprayed in two stages of green tip and pink tip of bud, in a split-factorial experiment in a randomized complete block design with 4 replications under field conditions. At harvest time, many of the qualitative and antioxidant characteristics of fruits’such as total soluble solid, organic acids, vitamin C, carotenoids, anthocyanin, phenol content were studied. Generally, the results showed that spraying at both stage increased qualitative and antioxidant characteristics of fruits compared with control fruits and between treatments, methyl jasmonate 200mgL-1 and combined with salicylic acid ImM had highest effect on improving quantitative characteristics of fruits and spraying at green tip was effective compared with pink tip stage.
