  In this paper, we study the GUP (Generalized Uncertainty Principle) modified
Hawking radiation of rotating polytropic black hole given in the
Boyer-Lindquist coordinates. To this end, the GUP modified Klein-Gordon
equation is applied for investigating the quantum tunneling of scalar particles
from the polytropic black hole. After reducing the obtained radial wave
equation to the one-dimensional Schr\"{o}dinger equation, we derive the
reflection and transmission probabilities of the radiation. A detail discussion
on how the reflection and transmission (greybody factor) probabilities are
derived for this black hole is given. The results are graphically depicted and
the relevant physical interpretations are made.
