A study of the chromosome number as related to stomata size has been reported herein for certain varieties of pineapples grown in Puerto Rico. The diploid strains studied were: Red Spanish, Eleuthera, Hondureña, Pan de Azúcar, Amarelo Boituva, Natal, Smooth Cayenne, Golden Abachi, Inerme Paulista, and Instituto Mayagüez. The triploid strain was Cabezona. The average size of stomata in the diploid strains was found to be 23.46 x 23.16 microns. The stomata of the triploid strain averaged 27.88 x 26.84 microns. The difference in the size of the stomata of the diploid and triploid strains was found to be highly significant.
