Abstract
The effect of the bacterial drug Rhizoactive and the stimulator Regoplant, as well as their combined use on the laboratory germination of seeds and the beginning growth stages of spring pea plants Oplot, were studied.Regoplant and the mixture Rhizoactive + Regoplant had the greatest influence on the processes of seed germination of spring peas during heterotrophic nutrition. Decrease in the crude mass of cotyledons was detected during the phase of transition of pea seedlings to autotrophic nutrition using the stimulant drug Regoplant and its combination with a bacterial preparation. It was accompanied by the activation of growth processes in the aboveground and underground parts of the seedling, in particular, an in crease in linear size and mass.The best indicators of sowing qualities of spring pea seeds were found when using a combined treatment of seeds with stimulant drug Regoplant and bacterial preparation Rhizoactive. There was an increase in germination energy by 3.0%, general germination by 2.0%, and germination simultaneity by 3.9% compared to control in this variant.
