The influence of the chlorella suspension on morphometric parameters of different taxonomical groups plants seedlings

Abstract

Microalgae chlorella contains a pool of biologically active substances, which creates the preconditions for its commercial production for use in agriculture, medicine, cosmetology and other areas of human activity. Specialized substances that affect seed germination, seedling growth and development, yield and decorative properties of plants for in vivo use are a wide variety. However, they can be toxic to humans and animals, as well as to the plants themselves. Biostimulants and biofertilizers based on macro- and microalgae have managed to establish themselves as an actual replacement for toxic substances, demonstrating high efficiency on plants of various taxonomic groups. The use of a biostimulant based on a suspension of chlorella in the study of seed germination and biometric parameters of seedlings showed the following results: leaf mass and volume, germination, stem and root length increased in plants of spruce, marigold, rye, barley, spelled, triticale, melissa, while in pine plants the germination decreased, and in cabbage plants it remained at the same level, which indicates a difference in the perception of chlorella suspension by plants of different taxonomic groups.
