Certain Morphological Characteristics in different Ploidy Level of Thai Banana

Abstract

The investigation on leaf thichnes, leaf weight, petiole weight, number and size of stomata, number and size of pollen grain off fifteen clones of Thai banana at different ploidy were conducted. Such characters were compared to thos eof wild diploid plants namely Kluai Pa (Musa acuminata) and Kluai Tani (Musa balbisiana) using X2 -test in experimental analysis. The results showed that 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 samller number of pollen grain were noticed in teh polyploids than in the diploid.
