Resumo
Solanum lycocarpum (lobeira) is a typical and abundant species of brazilian Cerrado, which
occupies mainly surrounding disturbed areas. It has interesting characteristics from the point of view of reproductive
biology, that probably are favoring the large occupation of habitats by the species. Based on the fact that the species
produces flowers and fruit during all the year, the present study had the purpose to verify the association between flower
and fruit production with environmental variables (temperature, relative humidity and precipitation), aiming to support
future studies referring to reproductive biology and ecology of plant species from Cerrado biome. A population of S.
lycocarpum composed of 34 plants in reproductive phase, situated in Morrinhos, south of the State of Goiás, Brazil, , was
evaluated. All the plants were geographically referenced with a GPS receptor. Observations were made monthly during 13
months (June, 2005 to July, 2006) quantifying open flowers and fruits produced in the intervals between the observations.
It was possible suggest high conversion of flowers in fruits. The Spearman rank correlation showed positive correlation of
flower number with precipitation and relative humidity. Fruit number was not correlated with the environmental variables.
