Hedron Rover landfall play land in response to magic gathering rules

[SlowFast]

If its my turn and I havent played my land for the turn yet

and someone lighting bolt my Hedron Rover

can I respond by playing my land and saving it from death?

No. You can only play a land if the stack is empty.

However, keep in mind that if it's your turn (and your main phase), your opponent has to give you the chance to play a land before he can do anything.

However, also keep in mind that he can just Bolt the Rover in response to its triggered ability and kill it anyway.
