Acer pseudoplAtAnus L., Acer plAtAnoides L. and BetulA pendulA Roth. as bioindicatoRs of uRban poLLution in sofia
Acer pseudoplatanus L., Acer platanoides L. and Betula pendula Roth. have been studied under the urban pollution in Sofia during 3 years period. The aim of the study was, by statistical multifactorial analysis, to assess the value changes in morphological parameters of species under air pollution and potential for species usage as bioindicators in observed regions. The statistical analysis incl...
متن کاملQualitative and Quantitative Changes in Proteins in Acer Platanoides L. Seeds during Maturation
Maturation of Norway maple (Acer platanoides L.) seeds produces deep physiological dormancy and resistance to desiccation. This study used two-dimensional electrophoresis to investigate the protein products of genes activated during the complex developmental process of maturation. Qualitative and quantitative changes in protein composition during maturation were tracked in this species. The mos...
متن کاملProteomic Analysis of Embryogenesis and the Acquisition of Seed Dormancy in Norway Maple (Acer platanoides L.)
The proteome of zygotic embryos of Acer platanoides L. was analyzed via high-resolution 2D-SDS-PAGE and MS/MS in order to: (1) identify significant physiological processes associated with embryo development; and (2) identify changes in the proteome of the embryo associated with the acquisition of seed dormancy. Seventeen spots were identified as associated with morphogenesis at 10 to 13 weeks a...
متن کاملRed reveals branch die-back in Norway maple Acer platanoides.
BACKGROUND AND AIMS Physiological data suggest that autumn leaf colours of deciduous trees are adaptations to environmental stress. Recently, the evolution of autumn colouration has been linked to tree condition and defence. Most current hypotheses presume that autumn colours vary between tree individuals. This study was designed to test if within-tree variation should be taken into account in ...
متن کاملLevels of selected trace elements in Scots pine (Pinus sylvestris L.), silver birch (Betula pendula L.), and Norway maple (Acer platanoides L.) in an urbanized environment
The aim of the study was to determine the concentrations of selected trace elements in needles and bark of Scots pine (Pinus sylvestris L.), leaves and bark of silver birch (Betula pendula L.), and Norway maple (Acer platanoides L.), as well as in the soil in which the trees grew, depending on their localization and hence the distribution of local pollution sources. The content of trace element...
