Fig. 2.

Cuticular wax composition in the leaf blade of wheat cv Xinong 2718. Wax coverage is expressed as μg dm^–2 of leaf blade surface area. (A) Composition of the leaf cuticular wax of seedling plants. (B) Composition of the leaf cuticular wax of flowering plants. Each wax constituent is designated by carbon chain length, and is labelled by chemical class along the x-axis. Each value is the mean of three independent measurements of individual plants. FA, fatty acids; Ald, aldehydes; Alk, alkanes; β-Dik, β-diketone; Alc, primary alcohols; OH-β-Dik, hydroxy-β-diketone; Est, esters; Uni, unindentified compounds. Error bars indicate the SD.
