Abstract

Ethylene was produced after the explants were cultured,and reached its maximum at the third hour and then decreased rapidly,when bud differentiation proceeded.The capacity of the cultured explants to produce ethylene was negatively correlated to its ability to differentiate.During bud diffrerntiation the level of ethylene production was low but it increased slightly before buds were formed.The ethylene antagonist Ag~(+)(1-10 #mu#mol/L) enhanced greatly the capacity of the explants to differentiate.Wounding may be the major factor reponsible for ethylene production of the culture explants.
