Effect of sunlight intensity on Malbec
- Increased altitude = Increased sunlight intensity.
- Increased sunlight intensity = Increased
photosynthesis.
- Increased photosynthesis = Increased secondary
metabolism.
- Increased sunlight intensity = Increased synthesis
- f beta-ionnona (Malbec).
- Increased sunlight intensity = Increased synthesis
- f phytoalexinas (resveratrol).
SLIDE 13
Physiological Effect of Sunlight Intensity on Malbec
Increased thickness = Increased concentration
- f anthocyanins & polimerized taninns.
