Does sugar influence maple leaf colour?
« on: 18/07/2012 13:30:07 »
Jeff asked the Naked Scientists:
   
If I poured a pitcher of sugar water on the roots of a sugar maple tree every day, would the leaves produce different colours than normal during the fall season.  (In Southern California)

What do you think?

Plants are not made to absorb sugar via the roots.
So the sugar you use will be digested by bacteria and fungi in the soil, which might lead to a lower pH caused by acetic acid produced (at least before complete reaction to CO2).
If you really put a lot of concentrated sugar you might even prevent the plant of absorbing water because of osmotic pressure.
If you do not care about your tree, you can try it. But I assume that you rather kill the tree or make it severely sick, which in turn might change the colour of the leaves. :-)
