Effect of nicotinic acid in defence of wheat plants against hypoxia under flooding stress

Aim. The aim of the research was to investigate induction Triticum aestivum L. non-specific tolerance by nicotinic acid hypoxia during flooding stress. Methods. Winter wheat plants cv. Ladyzhynka were grown in laboratory conditions and had been treated solution then stress started. hydrogen peroxide content leaves morphometric parameters measured experimental period. Results. It is shown that influence essential first hour After 96 hours balanced hydrogenous level close control. Conclusions. Nicotinic decreased under via regulation leaves. could on plant adaptation high humidity, decrease damage tissues prevent their loss flooding. be used as a perspective component for compound combinations induce complex stimulation defense against biotic abiotic stresses.
