Morfología del fruto plántulas sistema reproductivo tratamientos pregerminativos. Regeneration of bulbs of Hippeastrum striatum and Habranthus brachyandrus (Amaryllidaceae) subjected to longitudinal cutting. As an alternative for increasing the vegetative propagation of two ornamental promising species, Hippeastrum striatum and Habranthus brachyandrus, the capacity of vegetative regeneration of bulbs subjected to cut, was analyzed. For both species the number of bulblets was greater when the mother bulb was cut. In H. striatum 13 - 20 regenerated bulblets were obtained with diameters between 1.02 and 1.16 cm (x = 1.09 cm). In H. brachyandrus 16 - 23 new bulblets were obtained with diameters between 0.87 and 0.94 cm (x = 0.91 cm). The number of leaves in new bulblets varied between 5 to 0 leaves/bulb in H. striatum and between 3 to 0 in H. brachyandrus. For bulbs that were not subjected to cutting (control treatment), there was no production of bulblets in H. brachyandrus, instead, in H. striatum smaller size bulblets were obtained without signs of leaves development. The mechanical induction of bulblet development from mother bulbs, had a highly significant effect in the variables evaluated, stimulating the activation of basal scale buds giving rise to an asexual progeny of clonal origin. La capacidad de regeneración vegetativa de bulbos de Hippeastrum striatum y Habranthus brachyandrus sometidos a corte longitudinal, fue analizada como alternativa para la propagación vegetativa de estas especies ornamentales promisorias. En ambas, el número de bulbillos hijos producido fue mayor cuando el bulbo madre fue cortado. En H. striatum se regeneraron entre 13 y 20 bulbillos con diámetros que variaron entre los 1,02 cm y 1,16 cm (x = 1,09 cm). En H. brachyandrus se obtuvieron de 16 a 23 bulbillos con diámetros que variaron entre los 0,87 cm y 0,94 cm (x = 0,91 cm). La cantidad de hojas en los bulbillos regenerados varió entre 5 y 0 hojas/bulbillo en H. striatum y entre 3 y 0 en H. brachyandrus. Los bulbos que no fueron sometidos a corte (tratamiento control), no produjeron bulbillos en H. brachyandrus, en cambio en H. striatum se obtuvieron bulbillos de menor tamaño sin indicios de desarrollo de hojas. La inducción mecánica a través de corte longitudinal en los bulbos tuvo un efecto altamente significativo en las variables evaluadas, estimulando el proceso de activación de las yemas basales de las escamas originando la progenie asexual de origen clonal.
