Abstract
For the purpose of estimating heat shock as a protection activator, the aerial portion of seedlings of Fragaria×ananassa Duch. cv. Tochiotome were dipped in water at various temperatures. Salicylic acid accumulation and the expression of defense related genes after the heat shock treatment were examined. The results indicated that treatment at 50℃ was most effective, accompanying the accumulation of salicylic acid and mRNA of defense related genes. These results suggested that the heat shock treatment induced systemic acquired resistance in strawberry plants.
