The Mycorrhizae Reddit


The Mycorrhizae Reddit

Mycorrhiza - a symbiotic association between a fungus and the roots of a vascular host plant. The term mycorrhiza refers to the role of the fungi in the plants' rhizosphere, its root system. Mycorrhizae play important roles in soil biology and soil chemistry.

In a mycorrhizal association, the fungus colonizes the host plant's root tissues, either intracellularly as in arbuscular mycorrhizal fungi (AMF or AM), or extracellularly as in ectomycorrhizal fungi. The association is generally mutualistic, but in particular species or in particular circumstances, mycorrhizae may be variously pathogenic in the host plants.

Wikipedia: mycorrhiza

Arbuscular mycorrhiza - a type of mycorrhiza in which the fungus penetrates the cortical cells of the roots of a vascular plant. (Not to be confused with ectomycorrhiza or ericoid mycorrhiza.) Arbuscular mycorrhizas are characterized by the formation of unique structures, arbuscules and vesicles by fungi of the phylum Glomeromycota. AM fungi help plants to capture nutrients such as phosphorus, sulfur, nitrogen and micronutrients from the soil. It is believed that the development of the arbuscular mycorrhizal symbiosis played a crucial role in the initial colonisation of land by plants and in the evolution of the vascular plants.

It has been said that it is quicker to list the plants that do not form endomycorrhizae than those that do. This symbiosis is a highly evolved mutualistic relationship found between fungi and plants, the most prevalent plant symbiosis known, and AMF is found in 80% of vascular plant families in existence today.

The tremendous advances in research on mycorrhizal physiology and ecology over the past 40 years[when?] have led to a greater understanding of the multiple roles of AMF in the ecosystem. This knowledge is applicable to human endeavors of ecosystem management, ecosystem restoration, and agriculture.

Searching for Piriformospora indica

I've been trying to find a source for some piriformospora indica in the states or even abroad if it can be shipped. I can see that there's a fair amount of university and private research being conducted so I know it's obtainable. However, I've had no luck on a vendor. Any help would be appreciated, thanks!

Vaccinating 2" caliper B&B oaks with an Ecto-injectable

Hey folks, I am looking to inoculate a few dozen B&B oak trees in our nursery with the Horticultural Alliance's "DIEHARD Ecto-Injectable" product. I don't have access to one of the fancy expensive devices that you would usually use for deep "feeding" trees, so I was wondering if anyone has thoughts on an effective way to use this product for a person on a tight budget. For those unfamiliar, B&B rootballs are quite dense (think hardened clay), so a drench is not really possible without wasting a lot of the product. I was thinking to maybe create some wells in the root ball, apply the powder dry into the well (the product is water soluble), and then deep water afterwards. Thoughts or better ideas appreciated!

Mycorrhiza spores communicate?

Henlo. :)
If you pour spores to a deep pot and after a time the mycorrhizae connected to a plant at the top already but at the bottom is plenty spores they'll said to each other to "hey come up we are connected, why don't you join?" or the bottom spores only activated when the root connected to them / the already connected mycorhizzae touches them?

I hope it understandable.https://ibb.co/LkBFjDh

Thank you :)

Possibly a stupid question: Can processed sugar be fed to mycorrhizae?

I hope my question is not completely off base. Some tropicals do not like large amounts of calcium found in the molasses that I use to feed the mycorrhizae. I was wondering if other types of sugars could be used to feed beneficial fungi? Thank you.

Any mycorrhizae growers on here still active?

Hi fungus fans - Saw the last post here was about a year ago and wanted to see if there were still any active myco growers here.

Ericoid mycorrhiza

Hi folks,

I'm looking to buy some Ericoid Mycorrhiza for my blueberries. Any ideas where I might find some. I've looked on the net and can't find any in Canada. Closest I came was a UK website. Is this stuff that hard to come by?

Thanks

Here's an example of a so-called "trees knee", that is, a living stump of a Douglas-fir that has healed over with bark and is kept alive via mycorrhizal fungal connections between its roots to the roots of living trees surrounding it, who send it nutrients to survive in this sort of zombie nub state

Mycorrhizae in potted plants

Hi guys, I've been having a bit of a hard time finding actually photos of mycorrhizal fungi in potted plants. I think I found one, would someone please confirm these are mycorrhizae? Thank you,

Fungi treatment for stressed old maple ?

Hello, I am worried about an old maple which showed signs of disease or stress last summer.

Might a mycorrhizal treatment help support its recovery ?

I cannot think of any other treatment.

Cacao mycorrhizae?

Hey folks! Just found this sub and I have a noob-ish question about mycorrhizal fungi. I have a cacao plant that I'd like to inoculate w/mycorrhizal fungi. I found some scientific articles talking about the species that are generally associated w/ Theobroma cacao and I am curious if cacao will form a mycorrizal association with other fungus or if it has to be the specific fungus from their native range. https://link.springer.com/article/10.1007/BF00041370 This is one of the articles. In general, do plants form this kind of relation with only one or a few fungi or are they more accepting of a wide variety of fungi? Sorry I know this is a strange question, I'm having trouble finding answers online. I just don't know if I can buy some mycorrhizae online and expect them to colonize the roots of my cacao.

I want to inoculate my nursery container stock of oaks and other trees with wild mycorrhizae. Anyone have experience with this?

I work at a native plant nursery and riparian buffer installation company. We want our oaks to survive better and i wondered if taking soil from a succesful oak tree in the forest and putting small amounts of it in the containers in the nursery would reliably inoculate the oaks and give them better survivorship out in the field. I assume mycoapply would have the right species, but we'd rather do it for semi-free.
