Perrenniophora on Plane

[alliaria]

Hi everyone, Scenario, sorry no pics, but I can post some if needed later, mature plane by a major road, P. fraxinea on two sectors, fairly large fruiting bodies. The tree was reduced by 40% one year ago,I know, showing peripheral canopy dieback and sparse foliage cover, little responsive/epicormic growth. The thing is that it is shedding/exfoliating bark from root and trunk. This is revealing underlying tissues which would obviously be vulnerable to a number of climatic factors.

Is this a response to reduced photosynthetic capacity?

Anyone got any info. on the effect of p. fraxinea on plane, Platanus x acerifolia syn. P x acerifolia.

Sorry about the length of this post.

Cheers.

is that the one by bedminster bridge?

Until now, in The Netherlands I've documented P. fraxinea on Platanus spp. three times. All trees were heavily reduced before, leaving the major roots and the endomycorrhizal microfungi associated with them no longer supplied with energy/sugars behind, which caused the no longer adequately protected and "nurtured" major roots to partially die without Platanus as a species being able to regenerate major roots insufficiently supported by a for the greater part defoliated crown. The mycelium first "empties" the sugar/starch rich radial rays before it starts decomposing the central wood column of the tree base at or below ground level.

Other (biotrophic) parasites attacking Platanus under these circumstances are Meripilus giganteus, after loosing its major roots triggering the tree to form a dense secondary root system of adventitious roots around the trunks base to supply the remaining crown with water and nutrients and Pholiota squarrosa, mainly undermining the buttresses, major roots and trunk's base beneath ground level and destabilizing the tree.

Thanks Gerritt,

It also has a rat nest between butresses under the pavement, never seen that before,

Yeah Sean, on York Road.

Cheers

This one of those great dilemas, the tree is colonised by a fungi, causing a hazard, the tree must be reduced to reduce the hazard, but the balance is often tipped by the defoliation in the fungis favour and terminal decline becomes more rapid.

 

It takes a lot of experience and good judgement to work a tree down in a way that maintains the balance in the battle between food production and defence. It isnt an exact science.

 

We have to remember that defence is the trees last use priority for reserves, putting survival and seed production and maintenance above defence.

 

We need ways to increase vitality if we want to retain compromised trees.

Hi Tony,

I,ve read your posts with interest, you are obviously a clever and committed person and your knowledge of fungi is very impressive.

However, I really dont need to be told about the balance of nutrition and canopy density/retention.

This tree is in a target rich environment and has an obvious defect that may result in whole tree failure. Increased nutrition or whatever, can only be achieved by trunk injection as the tree is tarmacced up to the trunk and surrounded on all other sides by concrete.

The reduction, which I did not spec. is obviously going to impact on the photosynthetic capacity, and will probably tip the balance in favour of the primary pathogen, but a reduction may be preferable to removal , lets see what happens.

My boss would laugh at me if I suggested trunk injections to increase vitality, there is no money out there.

Please dont treat us in a condescending way.

Cheers.

I was making a statement of the situation we face in similar circumstances, youll NEVER recieve another post from me, I apologise.

Hi Hama,

You do tend to condescending side, my apologies if i,ve offended you.

Hi Hama,

No not offended me, I just hate the thought that anyone feels condesention in my replies, other than when it is actualy just sarcasm, which it wasnt in this case.

 

and no one likes having their flaws pointed out do they!

 

I get it from both my father and grandfather, they cursed me with it!

 

It is the thing i would most like to change but at 39 i think ive stopped trying and just go with it now!

Apologies again, I get my argumentative side from my old man too.
