Plant scientists are now able to measure the time it takes for corn plants to move water from their roots, to their lower leaves, and then to their upper leaves.
Patrick Schnable, Iowa State University plant scientist, says, this new, low-cost, easily produced, graphene-based, sensors-on-tape can be attached to plants and provide new kinds of data to researchers and farmers.
This type of tool will allow researchers to breed plants that are more efficient in water use. “We couldn’t do this before,” says Schable. “But once we can measure something, we can begin to understand it.”
