Concentrations of cellulose, lignin and nutrients in the stemwood of four clones of 7-year-old hybrid aspen (Populus tremula L. x P. tremuloides Michx.) were studied on 50 permanent experimental plots established for the afforestation of abandoned agricultural lands in Estonia. Quantitative evaluation of hybrid aspen chemical components indicated a relatively high cellulose and low acid-insolub...
درختان صنوبر کبوده و پده از گونه های بومی کشور ایران به شمار می آیند. صنوبر کبوده به لحاظ سازگاری و تولید چوب و فرم کیفی تنه برای فضای سبز و صنوبر پده نیز به دلیل مقاومت به شرایط اقلیمی گرم و خشک و شوری خاک از پتانسیل های بسیاری برخوردارند. در برنامه های دورگ گیری بین گونه ها، انتقال صفت شوری و مقاومت به تنش شوری از پده و انتقال صفت فرم کیفی تنه و رشد زیاد و زیبایی شکل از صنوبر کبوده از اهمیت خ...
Indole acetic acid (auxin) is a key regulator of wood formation, and an observed overlap between auxin concentration gradient and developing secondary xylem cells has led to the hypothesis that auxin regulates wood formation by acting as a morphogen. We dissected the role of auxin in wood formation by identifying the auxin-responsive transcriptome in wood-forming tissues and investigating alter...
Sucrose export from source organs, and its subsequent distribution among differentiating organs in wood-forming stems and elsewhere depends on the activity of sucrose transporters (SUTs). There are no comprehensive reports on SUT function in temperate tree species valued for their lignocellulosic biomass. To begin to address this gap, the SUT gene family was characterized and functionally analy...
Wood residues produced from forestry activities represent an interesting source of biologically active, high value-added secondary metabolites. In this study, 30 extracts from 10 barks of deciduous and coniferous tree species were investigated for their potential dermo-cosmetic use. The extracts were obtained from Fagus sylvatica, Quercus robur, Alnus glutinosa, Prunus avium, Acer pseudoplatanu...
