Abstract
Three seed coat sterilants were evaluated for effectiveness as surface sterilants and for effects on seed germination. Several exposure times in sodium hypochlorite, hydrogen peroxide and peracetic acid were evaluated. Seeds of the following crop plants were used: wheat (Triticum aestivum L.); sorghum [Sorghum bicolor (L.) Moench]; soybean [Glycine max (L.) Merrill]. All treatments reduced germination of wheat and soybean seed, but only the most severe peracetic acid treatments substantially reduced germination of sorghum seed. Considering both sterilization effectiveness and seed germination, a treatment with 5% sodium hypochlorite for 45 min appeared to be the most satisfactory of the treatments used.
