Trappe, J. M. Effects of the herbicides bifenox, DCPA, and napropamide on mycorrhiza development of ponderosa pine and Douglas-fir seedlings in six western nurseries. Forest Sci. 29 (3): – Google ScholarCited by: When we injured these Douglas fir trees, we found that a couple things happened. One is that the Douglas fir dumped its carbon into the network and it was taken up by the ponderosa pine. Secondly, the defense enzymes of the Douglas fir and the ponderosa pine were “up-regulated” in response to this injury. We interpreted that to be defense. Growth of Douglas-fir, lodgepole pine, and ponderosa pine seedlings underplanted in a partially-cut, dry Douglas-fir stand in south-central British Columbia Article Sep Abstract. Many references and unpublished data on outplanting performance of mycorrhizal inoculated seedlings are summarized. Two comprehensive tables are presented, one by fungus and one by host plant, as ready references to the literature for reforestation workers and scientists studying the effects of mycorrhizal inoculation on seedling performance after out-planting in the by:
Survival rates of artificial Pacific madrone regeneration were observed on 3 types of Douglas-fir-ponderosa pine stands in the Siskiyou Mountains of southwestern Oregon. The 3 stands were differentiated as: clearcut, 5 to 14 years old; a young conifer-hardwood stand, 50 to 80 years old; and an old conifer-hardwood stand, to + years old. Rhizopogon is a genus of ectomycorrhizal Basidiomycetes in the family s form hypogeous sporocarps commonly referred to as "false truffles".The general morphological characters of Rhizopogon sporocarps are a simplex or duplex peridium surrounding a loculate gleba that lacks a columnella. Basidiospores are produced upon basidia that are borne within the fungal hymenium that Class: Agaricomycetes. 1 DF = Douglas -fir, PP = ponderosa pine, SP = sugar pine. 2 Douglas -fir data are averages of shaded and unshaded seedlings. 3 Douglas -fir data for Blue Gulch, Miller Gulch, and Forest Belle courtesy of Pete Owston, PNW.

All of the Pinaceae (pine, Douglas-fir, and spruce) and most of the dicotyledonous, amentiferous trees, such as willow, oak, beech, walnut, and hickory, have ectomycorrhizae. The fungal symbionts of ectomycorrhizae are usually the common mushrooms that are found growing around trees during the late summer and fall. These fungi, onceCited by: 4.
Carbon assimilation by soil communities: mycorrhizae dominate the uptake and sub-service transfer of carbon between paired Douglas-fir seedlings. New Phytologist. Beiler, K.J., Simrd, S.W., Durall, D.M.(). Topology of Rhizopogon spp. mycorrhizal meta-networks in xeric and mesic old-growth interior Douglas-fir forests. Journal of Ecology. Old-growth interior Douglas-fir and ponderosa pine trees are able to minimize drought stress by keeping soil water potential high in shallow soils during drought via hydraulic redistribution (Domec et al., , Schoonmaker et al., ). Stomatal conductance and root embolism collectively aid in keeping shallow roots functioning and preventing Cited by: 5.

This revised and reorganized text is designed for a standard forest ecology course for undergraduates in forestry, natural resources, environmental science, environmental ecology, and field ecology programs.
