[Toxic effect of musk ketone based on the determinations of wheat (Triticum aestivum) seed germination and root elongation].
Through the determinations of wheat (Triticum aestivum) seed germination and seedling growth, the toxic effect of emerging pollutant musk ketone was investigated. The results showed that 10 mg x kg(-1) of musk ketone could significantly inhibit the seed germination rate (P < 0. 05) and the seedling's root- and shoot elongation of wheat (P <0.01), and there existed a significant (P < 0.01) dose-effect relationship between musk ketone and root- and shoot elongation, suggesting that the seedling's root- and shoot elongation of wheat could indicate the pollution extent of musk ketone in soil. The correlation analysis revealed that under soil musk ketone pollution, there was a significant (P < 0.01) positive correlation between root- and shoot elongation, and a significant (P < 0.01) negative correlation between seed germination and biomass. Besides the solubility in water, the toxicity of organic pollutant was related to its chemical characters, and its action mechanisms to the target organism.
