  • Ultrastructural alterations induced by tropospheric ozone: comparison between resistant and sensitive clones of Trifolium repens L. CV. Regal

    The effects of ozone on ozone-sensitive (NC-S) and ozone-resistant (NC-R) clones of Trifolium repens L. cv. Regal are compared at ultrastructural level by Transmission Electron Microscopy (TEM). Each clone were exposed to ambient ozone levels in the Botanical Garden of Rome, Italy, according to the ICP Vegetation Experimental Protocol (2005). TEM analyses showed that ultrastructural injuries ...
