Cím:	The effect of Cd-treatment on cyclic hydroxamic acid content of maize / Makleit Péter
Dátum:	2010
Megjegyzések:	The aim of this work was to examine the effect of Cd-treatment on cyclic hydroxamic acid content of maize. Application of Cd, as it is one of the toxic elements produce stress situation for plants. As cyclic hydoxamic acids are considered stress metabolites, it was postulated, that the concentration of the mentioned chemicals will change for the effect of Cd-treatment. 50, 100 and 150 micromol/litre Cd concentrations were applied for 1, 2 and 3 hours. The maize plants were 6 days old at the time of treatment. After one day of Cd-application the total cyclic hydroxamic acid content of roots and shoots was measured. The average cyclic hydoxamic acid content of roots was 230-350 mg/kg fresh weight. The shoots contained 490-590 mg cyclic hydoxamic acids/kg fresh weight. For the effect of Cd-treatment the cyclic hydoxamic acid content of roots and shoots decreased. The longer was the time of Cd-application, the higher was the Cd-concentration, and the lower was the cyclic hydoxamic acid content. It can be established that the direction of changes in cyclic hydoxamic acid concentrations depends on many factors, like the type of stress, plant species and variety.
