Citologia de duas bambusáceas brasileiras
Cytological studies of two species of brazilian bamboos determination of their chromosome numbers
Júlio César Medina; Dixier M. Medina
SUMMARY
Chromosome numbers are reported for the first time for two species of Brazilian bamboos. One is Merostachys speciosa Sprengel (known as "taquara lisa") with n=21 chromosomes and the other Chusquea sp. (known as "criciuma") with n=20 chromosomes.
According to the cytological behavior they can be considered as diploid; this suggests that basic numbers other than X =12 may exist within the Bambusaceae tribe.
Further accurate studies need be made about South American species that might possibly form series with different basic numbers from those determined until now for the Asiatic species.
