Figure 5.4 Changes in acetaldehyde and isoprene levels following light-dark transitions subjected to sycamore leaves. Note that acetaldehyde shows a rapid burst and decline during the dark period. The ability to measure such rapid changes in volatiles emitted from leaves illustrates one of the key benefits of PTR-MS. These results were replicated in several leaf varieties. Light intensity is given in terms of irradiance (E has units of W m ). Reproduced with permission from [223]. Copyright 2002 John Wiley Sons, Ltd.

As evidenced by the dendrogram in Fig. 4.3, separation down to species level is superimposed by a high similarity within genera. Examples for a high chemical similarity within the same genus are the spectra obtained from two species of Prunus, Bird Cherry and Wild Cherry. They form a distinct group, as do also two Acer species, Norway Maple and Sycamore Maple (see Fig. 4.3). However, the pollen spectra from a third species of Acer, the Ash-leaf Maple (or Maple Ash), resemble those of oak and sycamore tree pollen rather than the other Acer species. The tree is native to North America, different from the other two Acer species, which are natives to Europe and Asia.
