strange tissue on tree

[woodyguy]

I wonder whether these are more common in Eucs that form lignotubers?

I wonder if a section was cut from the tree and placed on the soil surface or a planting medium, It would propagate? If so how small a section would be required to do so.

 

Funny you should say that, I think there has been research into de-budding to produce this type of tissue to be used as a means of propagating species that otherwise are difficult to grow from cuttings.

Lignowhats? Do tell!

As I understand it, Lignotubors are grown by eucs that evolved with fire. Once the tree becomes large, an average fire will quickly burn off, aided by the bark that hangs from the tree. The Euc branches and foliage is lost but quickly regrows from the trunk. If fire is delayed (these days by Aussies building houses where they shouldn't) then when a big fire comes through it will burn so hot that it kills the trunk. The lignotubor is a big underground swelling that is fairly fire proof and from whence the tree regrows. See a similar thing in Musa Basjoo that many of us grow (a hardy banana).
