desert tree with cool survival technique
I know of a shrub, manzanita (Arctostaphylos spp.) which often has one
strip of living bark and wood connecting shoots with roots. You would see a seemingly dead bush, with just one leafy shoot and one stripe of red down an otherwise bleached-out trunk. Iris Cohen schreef I assure you it still has all the requisite parts, including the cambium layer. Iris + + + I guess that if it were really to come down to it a tree with living wood only will have a better chance of 'survival' than a tree with living bark only. Trees store their reserves in the wood. Wood often contain 'spare' growth points, from which a new axis can sprout. This will be a poor grade of survival, at least in the short term. Loss of bark and cambium will almost always result in the death of the tree-as-it-existed-before. It is somewhat academic anyway since much of the wood holding the reserves will be in the roots, which presumably must be more or less intact for any chance of survival to remain. PvR |
