THE VIABILITY OF CARROT AND CHICORY SEED AS AFFECTED BY DESICCANT SPRAYS
In general the loss of seed viability either from treated or untreated plants of both species has been slight (up to 10% about), except for carrot seed from the third and, mainly, the second crop year, being of poor quality because of adverse environments during harvesting.
Diquat and paraquat treatments didn't give, as a rule, germination percentages significantly different from the control, except for carrot seed from the second and the third crop year. Glyphosate spray slightly increased the germination of carrot and chicory seed of the first year crop and decreased it in the second one. Endothal showed a phytotoxic effect on seed of both species, which gradually disappeared during a 30 months storage period.
