Can seed quality of hairy fleabane be reduced due to glyphosate resistance?

Revista de Ciências Agroveterinárias, 2018
The resistance to glyphosate may provide a penalty on plant growth and physiology. We investigate if the resistance to glyphosate reduces the seed quality of Conyza bonariensis by performing seed viability and vigor tests under a completely randomized ...
