Oxygen is emitted as trees ad mass (wood or leaves) and create sugar for cell food. No tree has been identified as being more efficient than any other for this activity.The amount of oxygen generated by tree is dependant on the speed of its growth and the length of the growing season. As a consequence the youngest trees (saplings) are adding woody mass quickly and are producing oxygen at a high rate. Similarly the trees in tropical rain forests have a longer optimal period to grow and can emit oxygen for more days in a year.
You cannot determine which top ten trees produce the most oxygen. It does not go by the type of tree as much as it goes by the individual tree. A tree's age, and health impact how much oxygen is produced.
The most popular type of Christmas tree in the US is the Pine tree.
