Chlorophyll index in maize plants grown from seeds treated with reglalg and hypothermic shock

The article presents the results of studies of the influence of the use of the biostimulator Reglalg and negative temperature stress (NTS) on the chlorophyll index of maize plants grown in field conditions at the experimental area of the Institute of Genetics, Physiology & Plant Protection, MSU. Growing maize from seeds treated before sowing with Reglalg and then subjected to temperature treatment at -4°C for 16 hours showed that the use of Reglalg reduces the negative effect of NTS and contributes to an increase in the chlorophyll index of leaves in the early period of plant growth.
