The relationship between the growth retardative effect of CCC and ethylene production.
The ethylene production of the hypocotyls of CCC-treated bean plants was studied, and it was concluded that the treatment induced changes in the quantity of ethylene produced by the apical and basal hypocotyl parts. The ethylene production of the basal hypocotyl parts showed considerable increase on the effect of the treatment, in comparison with the control. The obtained results suggest a possible relationship between the longitudinal-growth inhibiting, stem-thickness inducing, root-formation stimulating effects of CCC and the effect exerted on ethylene production.
