Developing Ambient Almond Orchard Volatile Mixtures for NOW Bioassay Analyses

1. Obtain three duplicate samplings of ambient almond grove volatiles via Tenax absorption. The three samplings will correlate to flight times of NOW (mid April, late June, mid September). 2. Determine the identity and relative concentrations of the major VOCs in the ambient grove bouquet via GC-MS analyses. The VOCs will be grouped as average of all three runs as well as according to flight of NOW. 3. Develop a minimum number of volatiles necessary for a corresponding synthetic blend. This blend will be utilized in these research laboratories during puff or EAG studies of NOW. 4. Make available via publication the successful volatile mixture for other researchers to utilize for NOW studies.
