In most populations of Solidago altissima, a small proportion of plants have a growth pattern in which the stem bends early in the season so that the apex is pointing downward (i.e., a ‘‘candy-cane’’ stem) then straightens up again later in the season. The majority of plants, however, do not show this pattern. Instead their stems remain erect from emergence through flowering and senescence. It ...

Plant traits, used by the invasive insect herbivores to find and select suitable hosts, can play an important role in host range expansion. With regard Lycorma delicatula, it is not well explored, however, how plant origin affects selection, whether native introduced plants differ their morphology, lifespan, as environmental requirements for growth. We addressed this issue our study through com...

Methanolic extracts from the aerial parts and roots of two Scutellaria species, S. alpina and S. altissima, and five polyphenols from these plants demonstrated a significant ability to inhibit the formation of advanced glycation end-products (AGE) in vitro. S. alpina, which is richer in polyphenolic compounds, had strong antiglycation properties. These extracts demonstrated also high activity i...
