The greatest amounts of ethylene were produced by the pistil, divided into the stigma, the upper and basal parts of the style, and the ovary, isolated from pollinated flowers. The level of ACC was also high in these parts. An increase in ACC content and ethylene production in the pollinated stigma suggests the participation of this hormone in processes occurring in the pistil after pollination. Considerable differences in the amount of ethylene produced by the corolla and the pistil show that these parts of petunia flowers differ greatly in their sensivity to this hormone
