Resumo: | Commercially bulbs of Hippeastrum hybridum are propagated by twin scales, which are cultured in wet vermiculite in the darkness until bulbil appearance. We showed that twin scales kept under sun light produced bulbils, that once transferred to the field, did not undergo severe light stress. They had higher bulb dry weight and due to the presence of green leaves they grew faster when transplanted to the field than bulbils produced from scales kept in the darkness. An intermediary treatment (a period of darkness followed by transference to light) confirmed the advantages of producing bulbils under sun light conditions. It appears that in the field, growth of bulbs from dark grown bulbils was retarded due to the strong competition among leaves and roots for nutrients and assimilates.
