During the research phase, a system was developed to clonally micropropagate silver maple. Explant performance was best on DKW medium with 10 nM thidiazuron, and explants commonly developed 1 7 shoots after three months and over 60 shoots that could be rooted after four months in vitro. Plants were rooted (>90%) and acclimatized under intermittent mist and transplanted to an outdoor nursery bed. However, results were different during the production phase when 90 clones were propagated. Shoot proliferation rates were lower, differences in clonal response and worker efficiency were apparent, mass rooting under mist was inconsistent and acclimatization problems arose. The mean rooting was 46% under mist because of uneven coverage. Only 56% of rooted plantlets acclimatized which resulted in an overall efficiency of 26%. Partial solutions included root initiation in vitro, and use of fog for acclimatization.

In the course of our group's investigation of members of the maple ( Acer) genus, a series of glucitol-core containing gallotannins (GCGs) were isolated and identified (by NMR and HREISMS). Among higher plants, only certain maple species are known to produce GCGs, compounds with potential nutraceutical and cosmetic applications due to their reported antioxidant, antidiabetic, anti-α-glucosidase, anti-glycation, anticancer, and skin health promoting effects. Herein, we sought to investigate whether the previously un-investigated silver maple (Acer saccharinum) species was also a source of GCGs. Nine phenolic compounds, including six GCGs, were identified (by HPLC-DAD analyses using previously isolated standards) as ginnalins A-C (1-3), maplexins B, D, and F (4-6), methyl syringate (7), methyl gallate (8), and 3-methoxy-4-hydroxyphenol-1-β-D-(6-galloyl)-glucopyranoside (9). In addition, one sesquiterpenoid, namely, pubineroid A (10), was isolated and identified (by NMR).

Physiology and biochemistry of leaf bleaching in prematurely aging maple (Acer saccharinumL.) trees: I. Hydrogen peroxide level, antioxidative responses and photosynthetic pigmentsEssential signaling processes such as changes in calcium mobilization, protein phosphorylation and gene expression are known to be modulated by hydrogen peroxide (H2O2). A lot of silver maple trees in the city of Osijek (Croatia) were noticed to have bleached leaves by early summer as well as during the whole vegetation season. In this study we aimed to investigate the processes that regulate H2O2levels in healthy (green) and prematurely aged (bleached) leaves. For that purpose, photosynthetic performance and antioxidative response of green and bleached silver maple leaves were studied. Bleached leaves had higher hydrogen peroxide level, a three-fold level of total soluble proteins as well as a lower level of ascorbic acid. Concentrations of chlorophylla, chlorophyllb, total chlorophylls and total carotenoids as well as maximum quantum yield of photosystem II were lower in bleached leaves. This indicated their impaired photosynthetic performance. Further more, bleached leaves were characterized by lower specific activities of the main antioxidative enzymes, which influenced their reactive oxygen species scavenging capability. The higher level of H2O2content in bleached leaves as the consequence of reduced antioxidative enzyme specific activities as well as ascorbic acid level could be the reason for the down-regulation of photosynthetic performance and premature aging of those leaves.

Performance of bare-root stock of Patmore green ash (Fraxinus pennsylvanica Marsh.), Dropmore basswood (Tilia × flavescens A. Br.) and silver maple (Acer saccharinum L.) growing in two sizes of "Field-grow" in-the-ground fabric containers (46-cm and 56-cm diameter) was compared with uncontainerized controls over a 4-yr period. Root systems of Field-grow plants examined were more fibrous; feeder roots penetrating the container wall were swollen adjacent to it. Large roots, especially of silver maple, also penetrated the seam between the side walls and plastic bottom. Field-grow silver maple and ash grew progressively less than control plants on or after the first growing season, indicating diminutive effect of the containers. Basswood, which was slower to establish, showed no such response until the fourth growing season.Key words: Fraxinus pennsylvanica ’Patmore’, Tilia flavescens ’Dropmore’, Acer saccharinum, nursery production, "Field-grow" containers
