Abstract: In order to explore the wound signal induced by mechanical damage in fresh-cut bamboo shoots, the effect of fresh-cut treatment on the damage signal transmission of bamboo shoots at different distances from the cutting site and the influence of methyl jasmonate (MeJA) on the synthesis MeJA and transmission of signal molecule in fresh-cut bamboo shoots were investigated with the exogenous signal molecule and its synthetic inhibitor salicylhydroxamic acid (SHAM). The results showed that the wound signal substance was generated at the cleavage site, and it could be transmitted to the adjacent uninjured tissue to increase the activities of phenylalanine ammonia lyase (PAL) and peroxidase (POD). MeJA treatment could increase the activities of PAL, POD, superoxide dismutase (T-SOD) and ascorbate peroxidase (APX) in fresh-cut bamboo shoots, while SHAM treatment had a certain inhibitory effect. Thus, it was hypothesized that MeJA could induce and participate in the synthesis and transmission of some damage signal after mechanical damage in fresh-cut bamboo shoots.
