Plant traits and ecosystem effects of clonality: a new research agenda.

abstract：BACKGROUND AND AIMS:Flavonoids have the potential to serve as antioxidants in addition to their function of UV screening in photoprotective mechanisms. However, flavonoids have long been reported to accumulate mostly in epidermal cells and surface organs in response to high sunlight. Therefore, how leaf flavonoids actu...
