Pound for pound, do pine needles vs. other kinds of leaves put out the same amount of oxygen? Deciduous vs. evergreen?

Possibly helpful:

Generally in temperate forests, deciduous trees might be expected to have higher rates of photosynthesis than needle-bearing evergreen trees. However, the situation might be expected to be the reverse in tropical forests where the evergreens are often broad-leaved.
