Would larger trees have stronger cells?
« on: 25/09/2014 22:30:01 »
Paul Anderson asked the Naked Scientists:
   If there are two pinus radiata trees given the same nutrition and in the same environment and if the idea is to stimulate the growth of one, then something has to be different. Either the larger tree has smaller cells and more of them, or  the  same number (approximately) but the sides of the cells are elongated. Would not this mean that a plank of wood made from the tree with elongated cells would be weaker than a plank of wood from the control tree?

If we then look at chemical growth factors being applied to human embryonic stem cells when trying to grow a replacement muscle might it then be inferior to a normally grown muscle?
What do you think?

Supossing both trees have the same genetic potential, nutrition and soil/climatic conditions, the only way to affect stem lenght would be applying plant growth regulators (hormones). The result would be elongated cells, and I guess they will be somewhat "weaker.
