We establish an almost sure scaling limit theorem for super-Brownian motion on R(d) associated with the semi-linear equation u(t) = 1/2 Delta u + beta u - alpha u(2), where alpha and beta are positive constants. In this case, the spectral theoretical assumptions required in Chen et al. (J. Funct. Anal. 254:1988-2019, 2008) are not satisfied. An example is given to show that the main results also hold for some sub-domains in R(d).
