I don't have enough information to answer that, but I do know one pedalai tree nearby that is about 8 years old, very healthy, beautiful thick side-branching all the way up, very wide, about 10m tall, and all the leaves have been non-lobed or only slightly lobed for a few years, but it has never fruited. On the other hand, in this same area I know several marang trees that fruited after 6 or 7 years. The climate here is always warm, but never hot, about 20° from the equator, so maybe pedalai will fruit faster in a hotter climate.
