Phytotoxicity of simulated napropamide residues for wheat and oat crops
Fitotoksičnost simuliranih ostataka napropamida za useve pšenice i ovsa
Apstrakt
The sensitivity of wheat and oat to simulated napropamide residues was tested using bioassay based on morphological parameters. The difference in calculated EC50, EC20 i EC10 values for root length, root fresh weight and shoot fresh weight indicate the difference in sensitivity of the species tested. Oat showed slightly higher sensitivity than wheat. For the achievement of the same level of inhibition (10 - 20 %) higher concentrations are needed for wheat in comparison to oat (2 - 4 times higher).
Ispitivanje osetljivosti pšenice i ovsa na simulirane ostatke napropamida izvedeno je primenom biotest metode, merenjem morfoloških parametara. Na osnovu određenih EC50, EC20 i EC10 vrednosti za dužinu korena, svežu masu korena i svežu masu izdanaka utvrđena je razlika u osetljivosti ispitivanih vrsta, pri čemu je ovas ispoljio nešto veću osetljivost. Za ostvarivanje inhibicije merenih parametara na nivou 10 - 20 % potrebna je 2 - 4 puta veća koncentracija za biljke pšenice u odnosu na ovas.
