The constituents of the essential oil of Stachys laxa Boiss. & Buhse growing wild in Iran were investigated by GC-MS for the first time. Thirty-three constituents were identified. Germacrene-D (40.1%), b -caryophylene (16.7%), b -phellandrene (5.5%), caryophyllene oxide (4.6%), linalool (3.2%) and ?-cadinol (2.6%) were found to be the major constituents of the oil.

To reveal the mechanism of resistance of pear against ring rot induced by SA, the influence of SA treatment on disease severity and plant defense enzymes were studied with Pyrus bretschneideri cv. Yali and Physalospora piricola Nose as the materials. It is interesting to note that the resistance of pear to P. piricola could be greatly increased by the treatment of 0.2 mM SA. In the present stud...

Herein, we report on the results of solventand sorbent-free HS-GC-MS (headspace – gas chromatography – mass spectrometry) analysis of the headspace volatiles (HSVs) of fruits of cultivated melon (Cucumis melo L. cultivar “ananas dinja” [pineapple melon]) and pear (Pyrus communis L. cultivar “Julska lepotica” [the beauty of July]), as well as of underground parts of carrot (Daucus carota L. cult...

Grafting is a technique that may affect plant tolerance to iron chlorosis in plants cultivated for their fruit. Therefore, the objective of this study was to evaluate the tolerance of non-grafted quince seedlings and pear grafted onto quince plants cultivated in pots with alkaline soil. The experiment was conducted in a greenhouse at the University of Cordoba, Spain, in pots (3 L) filled with a...

Abstract Pears (Pyrus) are one of the most economically important fruits worldwide. The Pyrus genus is characterized by a high degree genetic variability between species and interspecific hybrids, several studies have been performed to assess this for both cultivated wild accessions. These mostly limited resolving power traditional molecular markers, although in recent past availability referen...
