However, the proportion of the single phenylpropanoid compound, methyl
isoeugenol,was reduced by HT.HT increased the concentration of total soluble proteins in cv Parano, whereas in cv Splendid the concentrations
of chlorophyll and carotenoids decreased. The dry mass of main root was significantly reduced at HT in both cultivars, probably reflecting
reduced photosynthesis and carbon allocation costs to defence as a result of thermal stress. Limonene treatment was not sufficient to protect
carrot root growth from thermal stress.
