Abstract
We prove that every triangle-free planar graph of order n and size m has an induced linear forest with at least 9n−2m11 vertices, and thus at least 5n+811 vertices. Furthermore, we show that there are triangle-free planar graphs on n vertices whose largest induced linear forest has order ⌈n2⌉+1.
