Determinación Del Cariotipo en Heliconias Nativas De México

Abstract: Heliconia es un género que agrupa a especies tropicales y subtropicales; se distribuye de manera natural desde Brasil hasta México; la vistosidad de su inflorescencia permite su uso con fines ornamentales. Estudios cariológicos en Heliconia reportan especies con 2n = 2x = 22, 2n = 2x = 24 y 2n = 3x = 36 cromosomas. Debido a que en las especies de México se desconoce el número y morfología cromosómica, el presente estudio tuvo por objetivo determinar el cariotipo de Heliconia uxpanapensis, endémica de México, H… Show more

“…Seeds were placed in Petri dishes with a moistened lter paper base and subjected to germination conditions in a germinator (Achieva Basic Style, Seedburo, USA) at 25 ± 1°C (Garcia-Ortiz et al, 2023). Then, for cytological study, root tips of 1 to 2 cm were collected and pretreated with 0.04% 8-hydroxyquinoline at 26 ± 1°C for 2 h. Treated roots were xed for 24 h with Farmer's 3:1 (ethanol:glacial acetic acid) solution (Ortiz-Curiel et al, 2018). Once the roots were xed, they were washed three times with distilled water for 30 min in each rinse.…”
