Abstract
Summer-grown Hydrangea macrophylla subsp. macrophylla var. macrophylla (Thunb.) were exposed for 1 week to C2H4 at 0, 0.5, 2.0, 5.0, 50, or 500 mul.liter-1 in dark storage at 16C for defoliation before cold sto rage. The number of leaves remaining per shoot for all cultivars decre ased with C2H4 concentration, and >5 mul C2H4/liter was effective in d efoliating 'Kasteln', 'Mathilda Gutges', and 'Todi' but not 'Merritt's Supreme'.
