hi Mj
im not really knowledgeable enough to explain it, but it's a bit of an old wives tale really, leaves do reflect more green light than red or blue but not a huge amount more, and they only reflect certain wavelengths of green not all green light (depending on the shade of the leaf). also some green light passes through the leaf.
afaik, red and blue light is absorbed near the surface of the leaf and after a certain level the efficiency of it's use diminishes, whereas green light penetrates more deeply into the leaf and is absorbed there. also the fact it is both reflected by and passes through leaves makes it bounce around and penetrate the canopy - in theory anyway
