Resumo: In vitro morphogenesis of garlic plants (Allium sativum L.) is controlled by substances added to culture media and by environmental factors. The objective of this study was to assess the effects of vernalization of bulbils and of photoperiod on the process of in vitro induction of garlic bulbs. Shoot meristems were excised from bulbils vernalized for periods of 0, 30, 60 and 90 days and cultivated in vitro either under conditions of short photoperiod (11h) or long photoperiod (16h). Regardless of the photoperiod they were exposed to, plants micropropagated from meristems extracted from those bulbils vernalized for 30 or 60 days showed a rate of bulbing of 100%. Interaction between photoperiod and temperature was detected only in bulb fresh weight and plant height, thus showing the dependence between these environmental factors in the micropropagation of garlic. The time of exposure of plants to cold decreases the sensitivity to photoperiod for bulbing induction. Garlic plants grown in vitro present morphogenetic answers to the induction and development of thermo and photoperiod-dependent bulbils.

Este estudo teve como objetivo avaliar os efeitos da vernalização de bulbilhos e do fotoperíodo no processo de indução de bulbos de alho in vitro. Meristemas caulinares foram excisados de bulbilhos vernalizados por períodos de zero, 30, 60 e 90 dias e submetdos ao cultvo in vitro sob condições de fotoperíodo curto (11h) ou longo (16h). Independentemente do fotoperíodo a que foram expostas, as plantas micropropagadas a partr de meristemas extraídos de bulbilhos vernalizados por 30 a 60 dias apresentaram 100% de taxa de bulbifcação. Detectou-se interação entre fotoperíodo e temperatura apenas para massa fresca de bulbo e para altura de plantas, indicando, portanto, que há dependência entre essesfatores ambientais na micropropagação do alho. O tempo de exposição das plantas ao frio reduz a sensibilidade ao fotoperíodo para a indução da bulbifcação. As plantas de alho cultvadas in vitro apresentam respostas morfogenétcas positvas para a indução e o desenvolvimento de bulbos do tpo dependende de termofotoperíodo.
