Maritime pine (Pinus pinaster Aiton) and Saharan cypress (Cupressus sempervirens L. var. dupreziana [A. Camus] Silba) are two cone-bearing seed coniferous woody plants. The chemical composition of their essential oils, isolated from needles and leaves by hydrodistillation, was analyzed with gas chromatography (GC) and gas chromatography mass spectrometry (GC/MS). A total of 66 and 28 compounds ...

El objetivo de nuestra investigación es identificar los componentes químicos y evaluar in vitro, la actividad antibacteriana extractos las hojas Cupressus sempervirens L. arizonica del norte Argelia contra Pseudomonas aeruginosa ATCC 9027. La extracción se realizó macerando en disolventes polaridad creciente (cloroformo, éter petróleo metanol acuoso). Se un cribado compuestos fenólicos para una...

While monitoring the health of different ornamental and shade trees in Serbia, symptoms indicative cypress canker disease were observed young Cupressus sempervirens Belgrade urban area. Symptoms included tree mortality (specimens recorded with a change needle colour, branch decline or longitudinal bark cankers on stems resin exudates) appearance acervuli fruiting bodies cones. Using light micro...

The present work was aimed at identifying the IgE-binding epitopic regions on surface of Cup s 3 allergen from common cypress Cupressus sempervirens, that are possibly involved in cross-reactivity reported between Cupressaceae species. Three main were mapped molecular 3, PR-5 thaumatin-like sempervirens. They correspond to exposed areas containing either electropositive (R, K) or electronegativ...

The canker-causing fungus Seiridium cardinale is the major threat to Cupressus sempervirens worldwide. We investigated the production of terpenes by canker-resistant and susceptible cypresses inoculated with S. cardinale, the effect of these terpenes on fungal growth, and the defensive biotransformation of the terpenes conducted by the fungus. All infected trees produced de novo terpenes and st...

A new vagrant species of phyllocoptine mites, Leipothrix nagyi n. sp . collected from Zinnia elegans (Asteraceae) is described and illustrated Hungary. Further three eriophyoid were recorded for the first time in Hungary, viz. Aceria hippophaena (Nalepa, 1898) found on Hippophaë rhamnoides, Epitrimerus cupressi (Keifer, 1939) Cupressus sempervirens tanaceti Boczek et Davis, 1984 associated with...
