W przeprowadzonym doświadczeniu badano wpływ temperatury inkubacji na wzrost grzybni, kiełkowanie zarodników oraz indywidualny efekt biotyczny (IEB) grzybów Trichoderma harzianum, T. pseudokoningii i T. viride. Temperatury w zakresie 5-15°C hamowały wzrost grzybni i tworzenie strzępek kiełkowych badanych izolatów Trichoderma spp. Również wartość IEB zależała od temperatury. Wszystkie izolaty Trichoderma spp. silnie ograniczały wzrost patogenów tylko w temperaturze 20°C.
Seeds of 3 Polish cultivars: Jamira, Jastra and PN Mono 1 were steeped in water for 3 h, partially dried and then treated with water for 4 days at 25°C. This method was compared to the treatment with running water at 20°C for 2 h. Prolonged high temperature treatment decreased field and laboratory emergence and root yield. It had no significant influence on rate of emergence. Electrical conductivity of high temperature treated seeds water solution was very low (15 times lower than control seeds). Much better method of sugar beet seeds advancement seemed to be rinsing in running water for 2 h. This method decreased electrical conductivity about 3 times (comparing to the control), significantly increased field and laboratory emergence, rate of emergence and root yield.
