| Abstract:
It was found that the induction of gum formation by methyl jasmonate in the second internode of tulip stem was not affected by the inhibitors of ethylene production,  -aminooxyacetic acid and cobalt chloride, but these compounds inhibited ethylene evolution in a stem.
Application of ACC alone greatly stimulated ethylene production in tulip stem without induction of gum.
On the other hand application of ACC together with methyl jasmonate greatly accelerated gum formation in comparison to the JA-Me treatment alone. Based on of these results, the role of ethylene in gum formation induced by methyl jasmonate in tulip stem is discussed. | |
