The amount of Wood effect isn't related to the colour of the leaves, as these two photographs show. First a pair of trees, of definitely different colour ...

When you look at the same trees through a 720 nm filter you can see that they look basically the same ...

Incidentally, the Wood effect happens in very deep red, rather than in true near-infrared. You can prove this if you have a 720nm filter. Go outside on a sunny day and look through the filter at some foliage. It will be very faint, but you will see the glow.
