EFFECT OF COPPER ON SEED GERMINATION AND GROWTH OF FABACEAE PLANTS

Abstract

The article presents the results of a study on the effects of copper salts of various concentrations on seeds of zoned varieties of peas and lentils. According to the results of laboratory experience, the positive effect of copper ions was revealed at concentrations of 1-10 mg/l. The most optimal concentration of Cu2+ copper ions in the form of sulfate according to various indicators was 5-8 mg/l for peas. In parallel experiments with lentil seeds, it was found that a noticeable increase in the length and mass of sprouts by about 20% is observed at concentrations of Cu2+ ions 5-15 mg/ l, to a greater extent for copper chloride than for sulfate. And the mass of the roots is more responsive when treating seeds with solutions of 5-10 mg / l of Cu2+ ions in the form of chloride. The optimal concentration of copper chloride in our experiments with lentils corresponded to about 5 mg/l Cu2+.
