“…1b). The occurrence of the diffuse stage has been reported in several plant species (Sybenga 1992). It may be of the complete type in which whole chromosomes undergo decondensation, or it may be partial, where some part of the genome undergoes decondensation.…”

“…Avaliações realizadas por Techio et al (2006) confirmaram a ocorrência de anormalidades no processo meiótico desse acesso, indicando ser esta a possível causa da menor viabilidade do pólen. A condição artificial do meio, os reguladores de crescimento, o genótipo e a idade da planta têm sido apontados como principais fontes causadoras das alterações citogenéticas (Bayliss, 1980; Peschke e Phillips, 1992; Sybenga, 1992), que variam de não disjunção e duplicação cromossômica à aberrações cromossômicas estruturais (Sybenga, 1992 Os corantes nucleares utilizados (orceína acética e carmim propiônico) mostraram alta taxa de pólens funcionais (acima de 90%, Tabela 1; Figura 1D e E). Essa frequência de pólens viáveis não era esperada, uma vez que híbridos entre P. purpureum x P. glaucum são descritos como estéreis devido à irregularidades meióticas (Jauhar, 1968(Jauhar, e 1981Techio et al, 2006).…”

“…Our findings on quadrivalent pairing are in line with a previous review of autopolyploid meiosis which found a mean multivalent frequency (trivalents and quadrivalents) of 28.8% over 93 different studies (Ramsey and Schemske, 2002). It has also been shown that low numbers of multivalents does not necessarily suggest that preferential pairing behavior occurs (Sybenga, 1992;Sybenga, 1994).…”
