Conteúdo: |
Pineapple cultivars are normally diploids, however some triploids have been found. The 'Gigante de Tarauacá' is a native pineapple that produces large fruits (as much as 15 kg) in the region of Tarauacá, Acre State, Northern Brazil. Hypothesizing that this feature is related with polyploidy, we investigated its genome by means of chromosomal counting and flow cytometry, using the traditional diploid cultivar Pérola as a control. The chromosomal counting was performed by means of the Feulgen reaction, and the ploidy levels were compared in histograms by flow cytometry after the nuclei were isolated and treated with Propidium Iodide and RNAse. The somatic chromosome numbers and ploidy levels identified in the histograms by flow cytometry revealed the triploid nature of the 'Gigante de Tarauacá' (2n = 3x = 75) and the diploid status of 'Pérola' (2n = 2x = 50). To the best of our knowledge this is the first report of the triploid nature of the Gigante de Tarauacá. |
