Aspirin shown to help native grasses grow on restored land

When restoring former industrial or agricultural land again to its pure state, it is vitally necessary to reestablish floor cover vegetation akin to native grasses. According to a brand new examine, the addition of aspirin helps these grasses grow.

The medicine that we all know as aspirin is definitely the artificial type of a pure compound known as salicylic acid, which is present in willow tree bark and in different vegetation. Previous research have shown that it boosts stress resistance in agricultural vegetation like tomatoes, making them hardier.

Led by Dr. Simone Pedrini, scientists at Australia’s Curtin University lately set out to see if the compound would have an analogous impact on wild vegetation. To that finish, they coated the seeds of three native grasses – Austrostipa scabra, Microlaena stipoides and Rytidosperma geniculatum – with “very low concentrations” of salicylic acid.


Subsequent area checks have been carried out at a farm within the state of Western Australia, a area the place all three grasses happen naturally. When in contrast to management crops grown from non-coated seeds, it was discovered that the survival and development charges of seedlings grown from the coated seeds have been considerably increased.

“Further research is now needed to test salicylic acid as a coating in other wild species to improve native plant resistance to drought, extreme temperatures, salinity, pathogens, and herbicides,” says crew member Prof. Kingsley Dixon. “Moreover, coating with salicylic acid in combination with other beneficial compounds should be tested on a broader array of plant species used in restoration, as their combined impact on seed germination, emergence, growth and plant establishment could improve the successful deployment of native seed onto degraded landscapes.”

The analysis is described in a paper that was lately revealed within the journal PLOS ONE.
