Abstract

The parasite-host system Meloidogyne arenaria – Tiny Tim tomato plants has been studied in order to investigate the influence of the process of invasion on the chemical composition and biomass of plants. The concentrations of seven chemical elements Cu, Zn, Mg, K, Na, Mn and Fe have been determined using AAS in controls and invaded plants, and their changes have been evaluated under treatment with NH4VO3 in three different concentrations – 0.01, 0.1 and 0.13 mg/100 ml H2O. The process of treatment with NH4VO3 disbalances significantly the trace element content of plants. The lowest concentration (0.01 mg NH4VO3) causes bigger changes in the concentrations of Mn, Fe and Na in non-invaded plants. The highest concentration (0.13 mg NH4VO3) balances the content of the elements back to their levels in the control plants for the elements Zn, Fe and Na. The pure effect of the process of invasion with Meloidogyne arenaria on the biomass (leaves, stems, roots and total biomass) of Tiny Tim plants is expressed in a significant increasing, mainly due to the development of the parasites. After treatment with different concentrations of NH4VO3 the decreasing in the biomass of leaves, stems and roots is observed which reflects on the total biomass of plants. The concentration of NH4VO3 eliminates the unfavourable changes not only in the chemical content of plants but also in their biomass. It could be taken into consideration as an alternative method used instead of treatment with nematocides.
