Abstract: Effects of Zn2+ pollution on Zn2+ uptake,chlorophyll concentration and characteristics of visible-near infrared spectrum of wheat(Triticum aestivum)were studied with solution culture,and relationships between them were discussed.The results indicate that the content of Zn2+ in Triticum aestivum increased while the concentration of chlorophyll decreased with the increase in Zn2+ concentration in the solution.Corresponding change in spectral characteristics of the leaves of the plant was observed.The spectral reflectivity ascended in the visible light zone and the strength of blue shift of the red edge intensified,showing significant correlationship.Meanwhile Zn2+ pollution affected spectral reflectivity of the leaves in the near infrared band,but the correlativity between the two was not so significant.
Key words: Zn2+chlorophyll, Triticum aestivum, spectrum, plant indicator
