Abstract
Pre-harvest treatments with 2 mM salicylic acid (SA) and 0.2 mM methyl jasmonate (MeJA) significantly reduced lesion
diameters on sweet cherry fruit caused by Monilinia fructicola compared with control post-harvest treatments. Pre-harvest
treatment of sweet cherry with SA or MeJA induced -1,3-glucanase, phenylalanine ammonia-lyase (PAL) and peroxidase
(POD) activities during the early storage time. The efficacy of inducing resistance in sweet cherry fruit pre-harvest-treated
with SA or MeJA to M. fructicola was better than that for fruit with post-harvest treatments, especially, at 25
?
C. Activities of
-1,3-glucanase and PAL in SA- or MeJA-treated cherry fruit stored at 25 ?C for both pre- and post-harvest treatments were

C. SA with a concentration of 2 mM showed direct fungitoxicity on M.
ructicola and significantly inhibited mycelial growth and spore germination of the pathogen in vitro. MeJA at 0.2 mM had little
nhibitory effect on mycelial growth and spore germination of M. fructicola. The fruit treated with MeJA pre-harvest expressed
igher activity of -1,3-glucanase and PAL than fruit treated with SA and the control during the early storage time.
