This study was to examine the effects of ethephon with calcium acetate on the maturation and qualities of 'Campbell Early' grapes (Vitis labruscana). The maturation of grapes was delayed 4 to 7 days when ethephon with calcium acetate was applied before and at veraison, but it was hastened 4 to 5 days when applied after veraison. Calcium acetate could not completely offset defoliation caused by ethephon treatment in weak vine and especially in vineyards under unfavourable environment for air drainage
