Figure 4.

The dynamics of stigma receptivity and activity of POD, SOD and CAT over time after blossom. “−” means the stigma is not receptive; “−/+” means that some of the stigmas are receptive; “+” means the stigma is receptive, and more “+” symbols mean the stigma is strongly receptive. The red vertical lines refer to time of natural corolla abscission, and the blue vertical lines refer to time of corolla abscission after anti-robbing.
