It is not obvious, and requires some experience with ‘handle diving’ into graphics objects.

Try this:

H = tf([2 5 1],[1 3 5]);                    % Define System
pzmap(H)                                    % Create Plot
hm = findobj(gca, 'Type', 'Line');          % Handle To 'Line' Objects
hm(2).MarkerSize = 20;                      % ‘Zero’ Marker
hm(3).MarkerSize = 20;                      % ‘Pole’ Marker
