Subject: Would watering a plant with sugar solutions positivly effect the grow of th

I introduced one of each carbohydrate (sucrose,fructose,glucose,lactose, 
and starch) solutions at 0.05m concentrations to different hydroponic units 
containing Brassica rapa after the Brassica were a week old. I expected the 
plants to incorporate the carbos into themselves by diffusion through the 
roots and then transport into leaves where they would be stored as starch 
molecules. In turn, I expected the starch concentration to increase along 
with growth of the plant. But I had some strange results; although the 
trend seemed to be a higher concentration of starch, the plants looked 
stunted and turned red/purple/yellow(they should be green!) maybe due to 
osmotic stress? We felt results were hard to interpret and wondered if any 
one had ever documented an experiment like this before. I have looked for 
days through several data bases and haven't found it yet.  I also wondered 
what kinds of carbohydrates are synthesized by Wisconsin Fast Plants 
(Brassica rapa). Could you please help or point me in the direction of a 
similar experiment? Thank you!
