Influence of simulated imazethapyr soil residues on the whole protein content in different crops roots

The bioassay conducted in controlled conditions was used to investigate the sensitivity of selected crops (maize, sunflower, wheat, sugar beet, oilseed rape and mustard) imazethapyr carryover. dešendence whole protein content test plants roots measured regard different concentrations soil. rates were established at 240, 120, 60, 30, 15, 7.5, 3.75 1.875 mg A.I. kg-1 soil (ppbw). After sowing, grown a growth chamber for 14 days afterwards carefully removed from pots intact, while root system by gentle thorough washing. Whole contents based on nitrogen using distillated method. Each treatment performed four replications bioassays each plant species repeated twice. Statistical analysis ANOVA, Tuckey determine significant differences. There no dependence herbicide concentration. A slight increase determined maize roots. same goes mustard rape. In wheat sunflower there decrease some treatments comparison control (imazethapyr ≥ 15 soil, ≤ 7.5 sunflower). If results obtained this study are considered together with earlier level imazethapyr, one can say that highly sensitive is always an when compared control. (the least tested here) observed only higher concentrations.
