The main factors triggering and releasing bud dormancy are photoperiod and temperature. Their individual and combined effects are complex and change along a transition from a dormant to a non-dormant state. Despite the number of studies reporting the effects of temperature and photoperiod on dormancy release and budburst, information on the parameters defining these relationships is scarce. The...
Eight strains of Trichoderma species (T. strigosum, T. erinaceus, T. pubescens, T. stromaticum, and T. spirale as well as T. cf. strigosum, T. cf. pubescens) were selected because of their antagonistic potential against Eutypa dieback and Esca which are fungal diseases of grapevine trunks. These isolates were screened for the production of a group of polypeptide antibiotics named peptaibiotics,...
Poison ivy, Toxicodendron radicans, and poison oaks, T. diversilobum and T. pubescens, are perennial woody species of the Anacardiaceae and are poisonous, containing strong allergens named urushiols that cause allergic contact dermatitis. Poison ivy is a species distributed from North America to East Asia, while T. diversilobum and T. pubescens are distributed in western and eastern North Ameri...
The aim of this work was to characterise wine-related wastewaters and ascertain the wastewater concentrations that were optimal for treatment by Trametes pubescens. Laccase production was also monitored. Crudely purified laccase was tested independently to determine its role in phenolic compounds degradation and colour change. The fungal treatment resulted in decreases in the wastewater chemica...
Biogenic volatile organic compounds (BVOC) emitted by plants can originate from both anabolism (metabolite production through anabolic processes) and catabolism (metabolite degradation by oxidative reactions). Drought can favor leaf oxidation by increasing the oxidative pressure in plant cells. Thus, under the precipitation decline predicted for the Mediterranean region, it can be expected both...
Although cold hardiness is known to be a major determinant of tree species distribution, its dynamics and the factors that regulate it remain poorly understood. Variation in cold hardiness and carbohydrate concentration, from dormancy induction until bud burst, were investigated in populations of two deciduous (Quercus robur L. and Quercus pubescens Willd.) and one evergreen (Quercus ilex L.) E...
• The mycorrhiza of orchids represents an energy source that may replace or supplement photosynthesis. Dependency on mycotrophy in adult life stages would thus be expected to be inversely related to the prevalence of phototrophic structures. • The phenology of underground parts and mycorrhizal infection were monitored in five terrestrial species differing in leaf phenology (and thus in phototro...
سابقه و هدف: آویشن گیاهی متعلق به خانواده نعنا است که با نامهای مختلفی نظیر "صَعتر"، "آبشَن" و "کَهلیک اوتی" در طب سنتی ایران شناخته شده است. در طب سنتی ایران از سه نوع آویشن تحت عنوان "برّی"، "بستانی" و "جبلی" نام برده شده است. در این مقاله سعی شده تا نامهای علمی این سه نوع آویشن با توجه به مشخصاتی که در کتب طب سنتی برای آنها ذکر شده تعیین و نامهای فارسی مناسبی برای آنها پیشنهاد شود. نتیجه اینکه م...
The essential oil from the aerial parts of Aaronsohnia pubescens subsp. pubescens plant (APS oil) was extracted by hydrodistillation, and then its composition was analyzed by gas chromatography (GC) and GC-mass spectrometry (GC/MS). We identified thirty-four constituents presenting 87% of the total amount, Which, Carvacrol (13.9%), α-Pinene (10.3 %), E-Anethole (10.1%) and Ar-Turmerone (9.3%) w...
