Abstract:
... The olive fly, Bactrocera oleae (Rossi), is a monophagous pest that displays an oviposition preference among cultivars of olive (Olea europaea L.). To clarify the oviposition preference, the olive leaf volatiles of three olive cultivars (Cobrançosa, Madural and Verdeal Transmontana) were assessed by headspace solid-phase microextraction gas chromatography–mass spectrometry (HS-SPME-GC/MS) at six d ...

MAs are biosynthesized from methionine via nicotianamine (NA). It is thought that only graminaceous plants synthesize MAs, whereas non-graminaceous plants synthesize NA which is involved in translocation of Fe within plants. In this report, using liquid chromatograp ...
