BEDOYA-CORRALES, Laura Isabel et al. Comparative study of germination percentage for Lactuca sativa varieties: sustainable orchards in urban environments. Rev. P+L [online]. 2018, vol.13, n.1, pp.83-91. ISSN 1909-0455.  http://dx.doi.org/10.22507/pml.v13n1a10.

Introduction.

Urban agriculture promotes the cultivation of vegetables in the city, however seeds are required to germinate and obtain seedlings that allow to start this practice.

Objective.

The present research evaluates the percentage of germination of two varieties of lettuce (Lactuca sativa), Milanesa and Conconina, to determine if there is a significant difference in their germination to obtain seedlings.

Materials and methods.

A factorial design 22 was developed, taking into consideration the combinations of variety and luminosity; a statistical model was proposed to describe its behavior.

Results.

The most influential factor in the percentage of germination is the variety, the best results were found Milanesa variety under natural Light conditions.

Conclusions.

The Milanesa variety is a good option to generate seedlings and, under natural Light conditions, a germination percentage of 92.5% can be obtained, a value higher than that reported by the producer.

Palavras-chave : germination; lettuce; factorial design; sustainability; urban gardens.
