We tested whether the pairing of selected isolates could be used to increase the efficiency of a decay fungus Chondrostereum purpureum (Pers. Ex Fr.) Pouzar to control hardwood sprouting in Finland. We paired C. purpureum strains efficient in sprout control or highly active in laccase production, and tested the efficacy of their progeny in spout control experiments. This procedure resulted in a...

We assessed the irradiance-related plasticity of hydraulic architecture in saplings of Betula pendula Roth., a pioneer species; Acer pseudoplatanus L., Fraxinus excelsior L. and Quercus robur L., which are post-pioneer light-requiring species; and Quercus petraea Matt. Liebl. and Fagus sylvatica L. Plants were grown in pots in 36%, 16% and 4% of full sunlight. Hydraulic conductance was measured...

This study investigates stable carbon and hydrogen isotope compositions of leaf wax n-alkanes from 3 angiosperm and 2 conifer species from a semi-desert natural environment. The dC and dD n-C27 alkane data show a clear distinction between Populus tremuloides/Syringa vulgaris ( 31.9 to 32.7‰ and 168 to 186‰, respectively) and Pinus sylvestris/ Picea pungens ( 28.8 to 30.6‰ and 190 to 212‰) throu...

Forest management in Sweden can be characterized by even-aged silviculture heavily relying on three established harvest regimes: clearcutting, the seed-tree method, and the shelterwood system. Less intense, small-scale retention harvest systems such as single tree and group selection harvest are rarely used. In addition, natural regeneration dynamics without enrichment planting have barely been...

We used in vitro callus and shoot cultures as target material for genetic transformation of silver birch (Betula pendula Roth) by particle bombardment. Cultivation of in vitro shoot cultures before particle bombardment and a long selection period, combined with a high concentration of selective agent after bombardment, led to the production of transformed plantlets that were stable, and no esca...

abstract introduction: diabetes is one of the most common endocrine diseases spreading rapidly in the world. diabetes complications are classified into acute and chronic. non-enzymatic glycosylation of body proteins such as hemoglobin and albumin is the main cause of pathogenesis in chronic complications of diabetes. protein glycosylation is an oxidative reaction. antioxidants such as vitamin c...
