The effect of insufficient nutrition on the development of the sunflower (Helianthus annuus, L.) root system

Popis výsledku v původním jazyce

One of the basic conditions for "physiologically normal" plant growth and development is a good supply of nutrients in the soil. The plant takes up nutrients from the soil solution via the root. The intensity of this uptake is based on a number of factors. One is the size of the root system and particularly the density of the root hairs. In a one-year vegetation experiment we studied how a deficiency of basic macro nutrients (N, P, K, Ca and Mg) affected the development and growth of the root system andaboveground mass of sunflower (Helianthus annuus, L.). The experiment was established as a pot experiment in the form of nutrient solutions (hydroponics) with known composition and concentration of ions. The development and growth of the root system innutrient-deficient conditions was evaluated during the initial stages of sunflower development using the LCR-meter (ELC-131D) which measures the root surface on the basis of electric conductivity. In the experiment we also monitored the a
