A, Ethylene production from pistils of dl and Nr in response to pollination. Individual pistils, isolated at anthesis (time 0) and at different times after pollination or mock-pollination, were enclosed in airtight vials and ethylene-sampled after 45 min. B, Ethylene production by petals isolated from pollinated and non-pollinated dl flowers. Flowers were pollinated or mock-pollinated at anthesis and collected after 24, 48, and 72 h. Isolated petals were enclosed in airtight vials for 45 min. Values represent means of at least 10 samples. Vertical bars represent se.
