In western forest ecosystems of North America, numerous dwarf mistletoe species are considered to be serious forest-borne disease agents.Severe dwarf mistletoe infection can result in a reduction in tree growth, premature tree mortality, reduced seed and cone development, and reduced wood quality, and increases the susceptibility of the host tree to pathogen and/or insect attack.
Mistletoe has many mythic associations, but the most popular by far is the Christmas tradition of compelling people to kiss under it. With white, red, or pink berries, and its romantic ...
