Strange callus and poor growth

[Tony Croft aka hamadryad]

the brown looking decay is that of hispidus, you also have what appears to be a borer in that those vertical holes are a feasting creeping beastie!

 

Sounds like these trees have had a tough time!

 

what was the site before planting? brownfield?

[chris cnc]

I understand spheroplast as a scientific term but that it is applied to describe the loss of cell wall structure....

Spheroplast - Wikipedia, the free encyclopedia

 

Spheroblast appears to be an invented term...( I can find no reference on internet either)

I do know what you mean chris cnc...I have a couple which I cleaned up and oiled and they sit on a mantle piece as " oddities/junk". They were taken from the floor around cedars....

Oh well....any one else with any thoughts as to either the meristematic disruptions or spheroplasts?

 

are they by any chance related to / the same thing as "burrs" ?

[Tony Croft aka hamadryad]

no, burrs and spheroblast are different things altogether, a speroblast is caused by an "iritation" of the area at least in my readings. interesting stuff, and something im going to have to go back to my books for, always love a chalenge!

[chris cnc]

theres a biiiiig old beech near me which has these "spheroplasts", or whatever theyre called, all over the underside of its main horizontal branches, im thinking it might have something to do with compression. just speculation, ill get some pics next time im passing

Did you find the quid in the tree as well?

 

 

Cracking top pic tho

 

He did say it was a cash tree

Seems like they've had it tough!

 

Strangely the site is incorporated into original farmland and what appears to be an ancient lane. Old hedgerow trees, oak, ash, field maple, hazel and thorn.

 

Just seems strange that only these planted ash have suffered.

Dave...Have you any references for the the term "spheroblast" ?

 

 

Hi Bundle 2

 

Sorry but this may be a duplicate reply (ones just got lost in web space) if you use the terms spheroblast combined with tree in google books there are a number of relevant entrys that differ in their description of spheroblast. Some entries state they only occur in mature trees and vary in size from that of a pea to the size of a walnut? other references state that a spheroblast is a tumorous growth within the trees tissues (which directly links to your description). to add further confusion to the issue:confused1:we have a mature Prunus avium on site that has a spheroblast ( or not) the size of a tennis ball 3m up the main bole?

 

love a good discussion

 

regards

Dave

[arb culture]

the brown looking decay is that of hispidus

 

How can you tell?

[arb culture]

Graham, a bit of a guess, but is there any chance the ash were shaded out by neighbouring trees?

 

Have you got any pictures showing a wider view of the growing location?
