Growth of Stuckenia pectinata under greenhouse and irrigation canal conditions in the lower valley of the Colorado River (Argentina)
Stuckenia pectinata is an invasive submerged weed in the irrigation district in the lower valley of the Colorado River, Argentina. The objective of this study was to analyze the initial growth of S. pectinata from tubers, and its annual growth cycle in irrigation canals, in order to be efficient in...
