Let PL(n) be the number of all plane partitions of n while pp(k)(n) be the number of plane partitions of n whose trace is exactly k. We study the zeros of polynomial versions Q(n)(x) of plane partitions where Q(n)(x) = Sigma pp(k)(n)x(k). Based on the asymptotics we have developed for Q(n)(x) and computational evidence, we determine the limiting behavior of the zeros of Q(n)(x) as n -> infinity. The distribution of the zeros has a two-scale behavior which has order n(2/3) inside the unit disk while has order n on the unit circle.
