Red 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 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 کاملSeasonal Occurrence of Xylem Embolism in Sugar Maple (Acer saccharum)
Xylem embolism, the reduction of water flow by air-filled vessels, was measured in a stand of 5to 8-year-old sugar maple (Acer saccharum Marsh.) saplings growing in a nursery bed in northwestern Vermont. Embolism was quantified as percentage loss in hydraulic conductivity of trunk and branch segments relative to maximum values obtained by removing air from vessels by repeated high pressure (173...
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...

Maple tap spot is one of the fungal diseases which has been infected maple trees. Early deciduous, the disappearance of leaf, reduction of growth, seed and wood production of maple trees are resulted due to this disease. The objective of this research was isolation and identification of the pathogen on leaves of Acer velutinum in Dr. Bahramnia educational and research forest (Shast-Kalateh of ...
