WEST LAFAYETTE, Ind. (21Alive) – Researchers from Purdue University found lowering temperatures for two hours each day reduces the height of corn crops without affecting its seed yield—a technique that could be used to grow crops in a controlled environment.
They say isolated and enclosed environments can stop genetically modified pollen and seed from spreading.
Researchers installed a growth chamber with insulation and yellow and blue lamps in a former limestone mine in Marengo, Ind. to grow the corn.
By dropping the temperature they were able to reduce the stalk height without affecting the number and weight of the seeds.
Researchers add the technique could be particularly useful for growing genetically modified crops processed into medicine and pharmaceuticals.
