Abstract
El objetivo del trabajo fue realizar observaciones en las protofilas de plántulas de tacaco. Se sembraron 50 semillas de tacaco, y se evaluaron las protofilas de las plántulas emergidas, hasta los 91 días después de siembra. Se encontraron protofilas con uno, dos, tres, cuatro, cinco, seis y siete lóbulos cada una. En la presente investigación se informa por primera vez sobre la existencia de heteroblastia (diferente número de lóbulos) en las protofilas de tacaco, lo que representa un hallazgo que puede ilustrar los cambios evolutivos recientes de esta especie.
The objective of the study was to make observations on the protophylls of tacaco seedlings. 50 tacaco seeds were sown, and the protophylls of the emerged seedlings were evaluated, up to 91 days after sowing. Protophylls with one, two, three, four, five, six and seven lobes each were found. This is the first notice about the existence of heteroblasty (different number of lobes) in tacaco protophylls; this could illustrate the recent evolutive changes of this species.
