Investigation on leaf thickness, leaf weight, petiole weight, number and size of stomata, number and size of pollen grain of fifteen clones of Thai banana at different ploidy were conducted. Such characters were compared to those of wild diploid plants namely Kluai Pa (Musa acuminata) and Kluai Tani (Musa balbisiana) using X2-test in experimental analysis. The polyploid had significantly thicker leaves, heavier weight, greater number of stomata, and larger size of stomata and pollen grain. However significantly less dry weight of petiole and smaller number of pollen grain were noticed in the polyploids than in the diploid.
