“…Paucity of detail cytological data, as well as the conflicting chromosome numbers reported in the genus so far, may be largely due to the extremely small size but the high number of chromosomes, the inter-clonal variation of chromosome numbers and dense cytoplasmic contents which make difficult in the cytogenetical analysis. The intraspecific variation of somatic chromosome number from previous reports in different Piper species indicated the presence of multiple basic chromosome numbers which is originated through different types of numerical and structural variations of chromosomes (Mathew 1958, Sharma and Bhattacharyya 1959, Smith 1966, Jose and Sharma 1985. The parent having different basic chromosome numbers can lead the breeding program unsuccessful (Huq et al 2007, Dash et al 2017).…”

“…Previous researches reported on chromosome numbers and conventional karyotypes of about 16 Piper species (Darlington and Janakiammal 1945, Sharma and Bhattacharyya 1959, Dasgupta and Datta 1976, Samuel 1987, Jose and Sharma 1985, Samuel and Morawetz 1989, Mathew et al 1999, Vossen and Wessel 2000.

“…Apenas 34 espécies do gênero Piper, todas asiáticas, apresentaram o complemento cromossômico caracterizado de alguma forma, mostrando ampla variação de número cromossômico entre espécies e até mesmo dentro de espécies (Dasgupta & Datta, 1976;Samuel & Bavappa, 1981;Jose & Sharma, 1985;Samuel et al, 1986;Joseph et al, 1999;Mathew et al, 1999).…”

“…Das 34 espécies de Piper estudadas até então, apenas P. cubeba (Dasgupta & Datta, 1976;Jose & Sharma, 1985), P. subpetulatum (Dasgupta & Datta, 1976) e P. futokazura (Dasgupta & Datta, 1976) apresentaram 2n = 24. As demais apresentaram número cromossômico múltiplo de 13 (Samuel & Bavappa, 1981;Jose & Sharma, 1985;Samuel et al, 1986;Joseph et al, 1999;Mathew et al, 1999), o que indica que o conjunto de espécies de Piper citogeneticamente conhecidas constitui uma linhagem única com x = 13 e vários níveis de ploidia (2x, 3x, 4x, 6x, 8x, 10x, 12x e 16x).…”
