Abstract Key message We examined the leaf structure of two basal Cupressus species with a distinct dimorphism. Some foliar features are regarded as ancestral and it is suggested that drought adaptation was one important ecological drivers in evolution genus. Leaf morphology anatomy species, C . nootkatensis vietnamensis , were investigated classical paraffin technique scanning electron microsco...

En un terreno de uso agrícola hasta el año 2004 se instalaron tres pequeñas plantaciones las especies Eucalyptus grandis (0.96 Ha), Pinus tecunumanii (0.3 Ha) y Cupressus macrocarpa (0.2 Ha). A los quince años la instalación midió profundidad del mantillo (Horizonte Ao) generado por descomposición materia orgánica procedente hojarasca prácticas manejo forestal. Además, tomaron muestras primeros...

Family Cupressaceae is the largest coniferous plant family. Essential oils of many species belonging to family Cupressaceae are known to have several biological activities specially antimicrobial activity. The essential oils from aerial parts of Calocedrus decurrens Torr., Cupressus sempervirens stricta L. and Tetraclinis articulata (Vahl) Mast. were prepared by hydrodistillation. The chemical ...

Vegetative shoots of Arizona cypress (Cupressus arizonica Greene) were found to contain an estimated 40 to 70 mug of gibberellin-like activity per kg. Based on elution patterns of silicic acid and celite partition columns, mobilities on thin layer chromatograms and specificity of the cucumber, d-3 dwarf maize, dwarf pea, and barley half seed bioassays it was possible to determine that the tissu...

The present paper reports the first record of Diplotomma cedricola (Werner) Etayo in eastern Mediterranean (Creta Island, Greece), being nearest from Corsica (France). This lichen species was found near Iérapreta on decorticated Cupressus sempervirens L. and Pinus brutia Ten. trees. finding constitutes a great expansion distribution range this species.
