MEDEIROS, Everton Maksud; BAUDET, Leopoldo; PERES, Wolmer Brod  e  EICHOLZ, Eberson Diedrich. Modifications in physical condition of carrot seeds with coating equipment. Rev. bras. sementes [online]. 2004, vol.26, n.2, pp.70-75. ISSN 0101-3122.  http://dx.doi.org/10.1590/S0101-31222004000200010.

The objective of this work was to evaluate physical quality of carrot seed run through an equipment developed for coating in function of adherence of several inert materials in different concentrations: agglomerate Vermiculite in proportions of 2:1 and 3:1; sticker Polyvinyl Acetate; and colorant "Color coat®", as well as addition of fungicide Thiram + Carbendazin (250ml for each 100kg of seed). Information was taken about carrot cultivar Tropical seed size, shape, weight and moisture. Using screens, it was detected that seeds remain isolated and modified size, weight and original form. The results obtained allow to conclude that the equipment for seed coating was functional in relation to the adherence of several layers, as well as the polymer + colorant produce satisfactory appearance to the seeds; the equipment was efficient in modifying size, shape and weight of carrot seeds; the Polyvinyl acetate was an efficient sticker for carrot seed coating and seed coating increased carrot seed moisture so seeds must be artificially dried for storage.
