Aerobiology of sweet chestnut (Castanea sativa Mill.) in north-west Croatia.
The aims of the study were to analyse characteristics of the Castanea airborne pollen and to compare aeropalynological data obtained from two sampling stations in north-west Croatia. The study was conducted in Zagreb and Samobor during the 2003-2006 periods, using the seven-day volumetric samplers of the Hirst design. In both study areas, the seasons of chestnut pollination were similar and las...
متن کاملCharacterization of Chestnut (Castanea sativa, Mill) Starch for Industrial Utilization
Studies were conducted to characterize the chestnut and its starch. Chemical composition of the chestnuts showed high level of starch. Moisture level in the raw nuts was around 50g/100g in wet basis and starch content, around 80g/100g in dry basis; other nut flour components were protein (5.58 g/100g), lipid (5.39 g/100g), crude fiber (2.34 g/100g) and ash (2.14 g/100g). Starch fraction was che...
متن کاملNutritional quality of chestnut (Castanea sativa Mill.) cultivars from Portugal
Chemical composition of eight sweet chestnut cultivars from the three protected designation of origin (PDO) areas in the Trás-osMontes region were studied: Aveleira, Rebordã, Trigueira and Zeive from PDO ‘Terra Fria’, Demanda, Longal and Martaı́nha from PDO ‘Soutos da Lapa’ and Judia from PDO ‘Padrela’. Chestnuts were characterised by high moisture content ( 50%), high levels of starch (43 g 100...
متن کاملSweet Chestnut (Castanea sativa Mill.) Bark Extract: Cardiovascular Activity and Myocyte Protection against Oxidative Damage
This work was aimed at evaluating the cardioprotective effects of Castanea sativa Mill. (CSM) bark extract characterized in its phenolic composition by HPLC-DAD-MS analysis. The study was performed using primary cultures of neonatal rat cardiomyocytes to investigate the antioxidant and cytoprotective effects of CSM bark extract and isolated guinea pig left and right atria, left papillary muscle...
متن کاملOrganic matter distribution and nutrient fluxes within a sweet chestnut (Castanea sativa Mill.) stand of the Sierra de Gata, Spain
The aboveground biomass, litterfall and its accumulation, litter weight loss due to decomposition and nutrient pools in relation to soil properties were analyzed in a Castanea sativa Mill. stand in order to better understand the recycling of elements associated with the turnover of organic matter. The aboveground biomass and the nutrient content were estimated by harvesting eight trees. In orde...
