Seed treatments with zinc, boron, biostimulant Coveron and MIX (zinc + boron + Coveron)
were applied to three lettuce and three celeriac cultivars. Seeds of three wheat cultivars were treated
under laboratory conditions with Trichoderma harzianum and eight Bacillus spp. Seed germination,
seedling growth, and the presence of the following pathogens were determined: Fusarium sp., Al‐
ternaria sp., Penicillium sp., and Mucor sp. The Coveron treatment was the most effective on lettuce
seeds tested in the germination cabinet. Seed germination was higher by 4% than in the control.
Alternatively, germination of seeds treated with boron in the greenhouse was higher by 12% than
in the control. The Coveron treatment had the highest effect on the shoot length, which was greater
by 0.7 and 2.1 cm in the germination cabinet and the greenhouse, respectively. This treatment was
also the most effective on the root length. Zn, B, and MIX treatments increased celeriac seed germi‐
nation by 14% in the germination cabinet. The Zn treatment was the most efficient on seeds tested
in the greenhouse. The germination was higher by 15%. A significant cultivar × treatment interac‐
tion was determined in both observed species under both conditions. The maximum effect on wheat
seed germination (8%) was achieved with the T. harzianum treatment in the Salazar cultivar. A sig‐
nificant interdependence (p ≤ 0.01 to p ≤ 0.001) was established between seed germination and the
seedling growth. The interrelationship between seed germination and pathogens of all cultivars was
negative.
