INFLUENCE OF HEAVY METALS ON WHEAT STEM DEVELOPMENT

Plants that grow in contaminated soil absorb and accumulate heavy metals in its above ground organs. Research was conducted in which content of heavy metals in wheat stem in phenophases of tillering and beginning of stemgrowth, and also stem hight of wheat from soil level to tip of appical leaf. The aim of research was to determine the influence of heavy metals on first stages of wheat varieties Pobeda and Ljiljana. Trial was conducted in pots with controled conditions of heat and moisture with adding different concentrations of heavy metals mixture. Higher concentrations of heavy metals had significant effect reducing the growht and wheat stem development of both wheat varieties. Significant concentration of heavy metals was detected throug analisis in stems of wheat.
