Mycorrhizae in Forest Tree Nurseries Michelle M. Cram and R. Kasten Dumroese Mycorrhizae are symbiotic fungus­ root associations. The colonization of roots by mycorrhizal fungi can benefit the host by improving nutrient and water uptake. In exchange, the host plant provides the mycorrhizal fungi carbohydrates (car­ bon) from photosynthesis.

Seedlings to be planted were nonmycorrhizal Douglas-fir and sugar pine stock grown in Ray Leach fir cells at Dean Creek Nursery, Oregon. Each seedling was placed in a planting hole to. Trappe, J.

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Many references and unpublished data on outplanting performance of mycorrhizal inoculated seedlings are summarized.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 Mycorrhizae on Douglas fir and Ponderosa pine seedlings book 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.

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.

It has been a major component of the forests of western North America since the mid-Pleistocene (30). Nurse logs such as the Douglas Fir decompose underneath the cascading root systems of Western Hemlock as they establish themselves, resulting in a root system that is stilted above the ground.

There is a growing body of research that recognizes the potentials of biochar application in agricultural production systems.

However, the diversity of ectomycorrhizal fungi and types of fungicide allows selection of the fungicide used depending on the fungus and situations that we desire to study. In general, herbicides and insecticides are less toxic to ectomycorrhizal fungi, and in nursery conditions and mainly in the field, their effects are low or by: 2.

As a first step in assessing the importance of plant-parasitic nematodes to California forestry, soil and root samples were taken from 32 kinds of trees in the major forested areas of California. Ninety-seven percent of the samples were from conifers, and 82 percent were from trees important in the lumber industry, mainly ponderosa and Jeffrey pines, coast redwood, Douglas fir, and red fir.

She recently launched a year experiment on Douglas firs, Ponderosa pines, lodgepole pines and western larch in 24 different locations in Canada. She calls it the Mother Tree Project.

We injured the Douglas fir by pulling its needles off [aww], and by attacking it with western spruce bud worm [ouch], and it then sent a lot of carbon in its network into the neighboring ponderosa pine. My interpretation was the Douglas fir knew it was dying and wanted to pass its legacy of carbon on to its neighbor, because that would be.
