Is it true that plants begin to consume oxygen around 45°C?

I used to work with a guy who had three PhD's. (two in Europe, one in the US). He had them in math, chemistry and biology. He said a few fairly outlandish things over the timeframe that I knew him, but every one I ever dug into it turned out was basically accurate.

One of the things he mentioned in passing, but which I haven't been able to confirm to my satisfaction is that when plants reach certain high temps, they start producing H2O2 instead of H2O. (around 45 Celcius)

I've read a few papers that seem to indicate that part at least is true, but I've never found anything that says whether or not this puts plants into the 'consumer' column for oxygen.

Anyone here able to point me to something that has this answer? or anyone here know the answer, even if it's not specifically been published yet?
