The
objective of this work was to evaluate pollen
dispersal from
transgenic to non-transgenic soybean plants.
Non-
transgenic soybean plants were
cultivated surrounding transgenic soybean plants carrying the ahas (for herbicide tolerance against imazapyr) and gus
genes. Pollen
dispersal was evaluated by the presence of both dominant
genes in the progenies of non-transgenic plants. The highest amount of
transgenic pollen dissemination was observed in the first row, 0.5m
distant from the central plot (0.44% to 0.45%). The frequency of pollen
dispersion has drastically decreased in the row 2 (0.04% to 0.14%),
reaching zero by the row 13, which was 6.5 m distant from the central
plot.
