Ash tree Question

[atree]

Why is it that ash trees have no signs of budding when every other tree is in full leaf?

 

And No they are not dead because every ash tree is the same with a maybe a few leaves starting to show life

 

Thanks

Old wives tale states........

 

"Oak before ash - in for a splash, ash before oak - in for a soak"

 

Not particularly scientific, but may have evolved from the observation of seasonal weather paterns over time.

 

what was your winter like ?

 

How far ahead are the Oaks?

Winter was not to bad,cold snap/bit of snow which never happends here (last time 60+years ago)

 

Oaks are in full leaf now same with most things.

Crow nesting low were gonna have snow,

Crow in the grass water up to your ass

 

Nature knows these things

Ash is generally the last tree to come into leaf. Ash wood (xylem) is classed as "ring-porous". This means that the tree has to grow a new ring of wood, containing the bundles of porous cells (tracheids and vessels) that can transmit water up to the leaves, before the leaves themselves are formed.

 

Therefore, although an Ash tree lookes dormant in the early spring it is in fact growing new wood.

Ah cool.Thanks

If it's of any consolation Adam we have the same thing here. I haven't known the Oak this full of leaf with the Ash showing no sign whatsoever. Had to triple check one the other day to make sure it wasn't dead and even then I still wasn't convinced. Meanwhile the Oaks have gone bonkers.

LoL

 

Yeah the oaks are normally the last to come into leaf down here anyway

But won’t the vessels from the previous couple of years be sufficiently “unlignified” to still have a vascular function? If your theory were true why is this characteristic not observed in all ring porous trees?

 

Could it be that the extended dormancy is an evolved trait (or what god intended depending on your belief system) that allows the tree to starve potential pathogens out before it shows the tender young shoots.

 

Could it be a combination of both

 

Either way at makes cracking firewood.

Thankyou for crediting me with the theory of ring-porous trees. I was actually paraphrasing from a book by Peter Thomas, Trees:Their Natural History page 49.

 

According to the theory ring-porous trees have evolved to combat air pockets developing in the water column (as a result of freezing and rapid thawing when in leaf) by growing wider and longer vessels in the early spring wood to move water more efficiently than the smaller, narrower vessel cells in diffuse-porous trees. However, because this is a risky strategy, they also produce smaller cells in the later wood. Should the large vessels become air-filled and stop conducting water then the smaller vessel cells from older rings are utilised. Ash appears to be the most extreme example of this trait but it is difficult to generalise about trees due to their independant evolution.
