“…Historically, apices, internodes, nodes, young leaves, and axillary buds were used as explants for regeneration of B. pendula and B. pubescens (Huhtinen, Yahyaoglu, 1974;Chalupa, 1981;Srivastava, Steinhauer, 198l;Simola, 1985;Ryynanen, Ryynanen, 1986). Currently, in vitro studies of birch continue to be carried out and focus largely on improvement of micropropagation conditions (Kontsevaya, 2009) and on investigation as to how environmental factors may influence rooting (Bojarczuk, 2000;Wynne et al, 2002) and general plant morphology (Ryynänen et al, 2005).…”

Background. Micropropagation of silver birch (Betula pendula Roth) is used to obtain healthy plant material for high-value plantations. The aim of this study was to evaluate the first steps of birch explant introduction and maintenance in vitro in order to make practical suggestions about the influence of these first steps on further micropropagation success.Materials and methods. Of the seven studied birch genotypes, one had been cultured in vitro for two years at the time of experiments, while six were newly planted in vitro from shoot segments disinfected after either one or two weeks of storage of collected branches. The explants were placed in glass culture tubes either on a hormone-free or cytokinin (6-benzylaminopurine)-supplemented medium.Results. A shorter branch storage time (one week instead of two) was better for the viability of explants, while external cytokinin, if used during the very first subculture in vitro, had largely a negative impact. Among the tested birch genotypes, 52BPL171 had the highest rate of viable explants and was followed in this respect by 01BPL115 which, however, contrasted strongly to the former because of its ability to maintain a green shoot apex alongside a green stem on the control medium. After 12 months in vitro, only genotype 01BPL115 was characterized by regular shoot growth and a well-developed root system.Conclusions. The green shoot apex on the control medium and, also, maintenance of viability on the medium with external cytokinin were found to be most helpful characteristics of birch explants during the first subculture, early recognition of those genotypes that would be most promising for obtaining multiple rooting shoots in vitro.

“…For example: genetical factors, implying that it can be successfully reproduced through vegetative propagation (Rohr & Hanus 1987); external stresses (Ewald & Naujoks 2015); and phytohormones like auxin and ethylene (Nelson & Hillis 1978). Efforts in reproducing these traits in sycamore maple and other wood species through vegetative propagation have been conducted and are ongoing (Bailey 1948;Ryynänen & Ryynänen 1986;Rohr & Hanus 1987;McKenna et al 2015;Ewald & Naujoks 2015). Regarding the mechanism of formation, the most widely accepted theory states that cambium cells' orientation is the primary factor in the formation of wavy grain (Hejnowicz & Romberger 1973;Savidge & Farrar 1984;Harris 1989).…”

Sycamore maple (Acer pseudoplatanus L.) is a wood species particularly known for its wavy grain figure and its high-value utilization among luthiers and craftsmen for making musical instruments or furniture. In this study, the anatomical and physical-acoustical characteristics of its wood, taken from different trees with various surface figure, were characterized. Vibrational mechanical measurements were conducted taking into account radial and longitudinal directions and local variations, waviness' parameters were quantified on split blocks, and anatomical properties such as microfibril angle and rays' dimensions were measured using light microscopy. Results provide a complete dataset on the properties of sycamore maple showing a gradient of wavy figure. Through statistical analysis, it can be concluded that there exist significant correlations between the measured parameters, particularly between waviness and microfibril angle, and between these anatomical features and the specific modulus of elasticity and damping by internal friction of the wood in longitudinal direction. Anisotropy was found to be very low but was not satisfactorily explained by the studied anatomical features. Prospects for future studies on wavy figure are introduced.
