| Abstract:
Treatment of tomato plants with trifluralin, diphenamid and chloroethyl phosphonic acid (CEPA) led to marked increases in rates of ethylene production by leaves, stems and apices; fluazifop-butyl had no such effect. The increased rates of ethylene production were to some extent correlated with the effects of the substances of growth and development. It is demonstrated that application of CEPA or ethylene to roots leads to enhanced rates of ethylene production in other plant parts. It is suggested that part of the effect of CEPA on ethylene production arises from stimulation of ACC synthesis in roots but that the major effect results from translocation of CEPA itself. | |
