Control of Dwarf Mistletoe
The dwarf mis t le toe Afeeu t 'hobh abietinum is a ser ious pa ras i t e of t r u e f i r s [Abies spp.) growing on the Pac i f i c Coast. Damage is most severe i n old-growth and unmanaged f i r stands. With information now avai lable , the fo res t manager can develop management guides f o r control of dwarf mistletoe. Such information includes parasite-host spec i f i c i ty , s i z e a t w...
متن کاملResistance of Ponderosa Pine to Western Dwarf Mistletoe in Central Oregon
Ponderosa pines with little or no dwarf mistletoe in infested stands on the Deschutes, Ochoco, and Rogue River National Forests in Oregon were tested for resistance to dwarf mistletoe (Arceuthobium campylopodum). Small trees produced by grafting scions from the resistant and susceptible candidates onto seedling rootstock were planted in 1967-69 beneath a heavily infested stand of ponderosa pine...

متن کاملNOTE / NOTE Dwarf mistletoe effects on fuel loadings in ponderosa pine forests in northern Arizona
Southwestern dwarf mistletoe (Arceuthobium vaginatum (Willd.) J. Presl ssp. cryptopodum) infests about 0.9 million ha in the southwestern United States. Several studies suggest that dwarf mistletoes affect forest fuels and fire behavior; however, few studies have quantified these effects. We compared surface fuel loadings and predicted fire behavior among four levels of dwarf mistletoe infestat...
متن کاملThermogenesis-triggered seed dispersal in dwarf mistletoe
Lodgepole pine dwarf mistletoe (DM), Arceuthobium americanum, is a parasitic flowering plant and forest pathogen in North America. Seed dispersal in DM occurs by explosive discharge. Notably, slight warming of ripe DM fruit in the laboratory can trigger explosions. Previously, we showed that alternative oxidase, a protein involved in endogenous heat production (thermogenesis) in plants, is pres...
