Genetically modified Norway spruce

Genetically modified Norway spruce

These trees are from the Forest Research Institute’s 2000 field trial of genetically modified trees. All the trees were sprayed with the same herbicide in varying amounts, from 1 kilogram per hectare to 4 kilograms per hectare. The trees at the bottom were genetically modified to make them resistant to herbicide. When sprayed, they survived, while the unmodified trees above died. Genetic modification remains a controversial issue in New Zealand.
