Cytotypes and Meiotic Behavior in Mexican Populations of Myrtillocactus geometrizans var. geometrizans (Cactaceae)

Autor: Rocío Cid, Guadalupe Palomino

Publikováno v: CYTOLOGIA. 61:343-348

Meiotic and mitotic chromosomes were analyzed in plants of three populations of Myrtillocactus geometrizans var. geometrizans (Cactaceae). Plants were diploid, chromosome counts were 2n = 22, n =11 (x =11). Karyotypes showed 11 pairs of metacentric c
