    due to high electronegativity of nitrogen in CN it pulls pi electron from the cyclic ring ad therby reducing the resonance effect and that is why negative mesomeric effect.and the triple bond which is sp hybridised and s character is high so it pulls electron towards it from the cyclic ring,so less resonance effect.
