Propylene and propene are synonyms for the same compound with the chemical formula C3H6.
If you meant "which is more reactive: propene or propyne", the former being the alkene (contains a double bond) and the latter being the alkyne (contains a triple bond), then propyne should be the more reactive.
This is, perhaps, due to the relatively higher steric accessibility of the 4 π(pi)-electrons in propyne (uncited).
