Abstract:
... Tree peony (Paeonia suffruticosa Andr.) has a short and concentrated natural fluorescence, and forcing culture is frequently used for its annual production. We previously found that defoliation is critical for tree peony to reflower in the autumn. In this study, we investigated how defoliation induced this process in more detail. We found that partial defoliation with only three top leaves remaini ...
