Abstract

Heavy metals contamination is considered as one of the most important environmental stresses, which leads to plant normal growth suppression. Accumulation of these metals in agricultural soils could threaten crop production. However, many investigations revealed that inoculation of some microorganism could mitigate the HEAVY METALS toxicity. Accordingly, this experiment aimed to investigate the effects of Trichoderma virens (TRI) fungi with AZOSPIRILLUM brasilense (AZB) and AZOTOBACTER chroococcum (AZC) on GERMINATION characteristics and seedling growth improvement of dill (Aniethum graveolens) using factorial experiment with three replicates during 2012. Treatments were combination four levels of copper nitrate (0, 40, 80 and 120 mg L-1) and four levels of biopriming [control (noninoculated), inoculation of TRI, AZB+AZC and TRI+AZB+AZC). Results indicated that GERMINATION characteristics responded differently to copper nitrate, in which root, shoot and seedling length showed a linear decreasing trend (slope of -0.005, -0.017 and -0.122, respectively) while fresh and dry weights of shoot and seedling responded as a quadratic equation. Trend of all parameters, with exception of daily GERMINATION rate, was increasing at the low levels of stress, whereas it was decreasing at the higher copper levels. Maximum value of these parameters was recorded at medium levels of copper nitrate. However, the effect of biopriming treatment and biopriming´copper interaction was not significant. In conclusion, it seems that repeat of similar experiments at other growth stages and growing medium could prepare comprehensive information about biopriming effect under heavy metal concentration.
