BACKGROUND: California is the second largest cultivator of pistachios, producing over 375 million pounds and a revenue of $ 787 million in 2009. Despite the agricultural and economic importance of pistachios, little is known regarding their actual volatile emissions, which are of interest owing to their potential roles as semiochemicals to insect pests. RESULTS: The ex situ volatile analysis of leaves from Pistacia atlantica, P. chinensis, P. lentiscus, P. palaestina, P. terebinthus, P. vera and P. weimannifolia demonstrated emission differences between species as well as between female and male leaves. Leaves from the female P. vera cultivars Bronte, Damghan, II, III, Kerman and Ohadi as well as fruits of P. atlantica, P. chinensis, P. lentiscus, P. palaestina, P. terebinthus and P. vera (cultivars II, III, Kaleh, Kerman, Momtaz and Ohadi) showed differences in the composition and relative quantity of major volatiles. The compounds in highest relative quantities from the various analyses were sabinene, Δ 3 ‐carene, β‐myrcene, α‐phellandrene, limonene, ( Z )‐ocimene, ( E )‐β‐ocimene and α‐terpinolene. CONCLUSION: This is the first ex situ survey of fruit and leaf volatile emissions from California‐grown Pistacia species and a number of corresponding cultivars. The study provides an overview of the major and minor volatile emissions and also offers evidence of chemotypes based on monoterpenes. The results highlight the dissimilarity of major components detected between ex situ volatile collection and essential oil analysis. Published 2011 by John Wiley & Sons, Ltd.
