So far the application of extract of sweet chesnut in diet and therapy was poorly studied. Samples of catkins of sweet chestnut and grafted Italian marrone cultivar have been collected in Bosnia and Herzegovina. The samples were milled for further analys ...

Abstract:
... Since 1963 when chestnut blight was recorded for the first time in Greece, the disease has spread into all 29 chestnut growing prefectures. As a result the national, annual chestnut production was reduced from 18,000 tons in the 1960s to 11,000 tons in 2005. A project for the application of biological control on a nationwide scale was funded and implemented during the period 2007-2009. Hypovirulen ...

Abstract:
... Phytophthora cinnamomi and P. cambivora are soil borne oomycetes that cause Chestnut Ink Disease, a lethal and widespread disease of the European chestnut (Castanea sativa Mill.). Soil moisture is a key factor for the onset of Phytophthora root rot epidemics. Zoospores are the main infective propagules that reach the roots by swimming in liquid environments, become encysted and after that infect t ...

Abstract:
... Soil organic carbon (SOC) is the major carbon (C) stock of the terrestrial biosphere with great importance for the balance of C at the global scale. So, a reliable estimate of the stored C in the mineral soil pool of forest ecosystems is of great importance. Inventory information on SOC stocks is very scattered, because of the inherent large spatial variability and the need of enormous sampling ef ...

Abstract:
... Morphometric methods are frequently used to study the variability of forest trees. As in many tree species the leaves of a single tree differ depending on the type of shoot, this must be taken into account when studying the morphological variability of leaf traits. This paper shows a methodological approach to the morphometric analysis of sweet chestnut leaves, using six different types of shoots: ...
