James Prigioni grows tomato plants from McDonald's cheeseburger seeds

American blogger James Prigioni conducted an experiment to determine if tomato seeds from a McDonald's cheeseburger could successfully grow into viable plants. Prigioni extracted two small seeds from a tomato slice and cleaned them, while simultaneously planting an entire untreated slice in a separate container.

After seven days, sprouts appeared under specialized lighting. Prigioni later transplanted the seedlings, growing one in an open garden and another in a five-liter plastic pot without using chemical aids. Within three months, both plants developed into large, productive bushes.

The plant grown in the open garden produced an exceptionally high yield, with branches bending toward the ground under the weight of the fruit. Interestingly, the experiment did not produce the large, round tomatoes typically found in fast-food burgers; instead, the plants yielded Roma tomatoes, which are oblong, firm, and sweet. Prigioni noted that the plants grown from the burger seeds appeared even more robust than those grown from commercially purchased seeds of the same variety.
