dwarfism of growth -- adaptation -- morphological variability -- fruiting

Аннотация: Dwarf and typical trees of Pinus silvestris L. in Shirinskaya forest-steppe are compared on variability of vegetative and generative organs and quantitative and qualitative characteristics of fruiting. Special attention is paid to investigation of the correlation structure of characters in the compared samples. It has been determined that the dwarf pines are characterized by high variability of dimensional and qualitative characteristics. In spite of generally low reproductive potential of dwarf trees some species are distinguished by regular and abundant fruiting. They are characterized by higher correlation of characteristics and tendency to gonochorism. In spite of generally small contribution of dwarf species into the reproduction of pine population, it is quite consistent with the small area occupied by rocks within the studied territory. Some species are distinguished by higher reproductive potential and may be used to solve the problems of selection.

    Wood-destroying properties of porodaedalea niemela m. Fischer and trichoderma atroviride bissett from permafrost area
/ Y. A. Litovka [и др.] // Khimiya Rastitel'nogo Syr'ya. - 2017. - Is. 1. - С. 145-150, DOI 10.14258/jcprm.2017011577 . - ISSN 1029-5151
Аннотация: Presents the results of a research of wood-destroying properties Porodaedalea niemelaei M. Fischer and Trichoderma atroviride Bissett. The strains were isolated in pure culture from the fruiting body and larch wood (Larix gmelinii (Rupr.) Rupr.) in permafrost. Studied phenol oxidase activity and biodegradation of waste wood at their solid-state fermentation. Under laboratory conditions, fungi colonize deciduous and coniferous substrates in monoculture and co-culture. Bioconversion depends on the enzymatic activity of strains and chemical characteristics of the growth substrate. Maximum of wooddestroying activity observed in strain PnB-13 Porodaedalea niemelaei on sawdust of aspen. The loss of weight of the substrate was 39%; polysaccharide content decreased to 1,6 times in comparison with the initial substrate; lignin - in 1.2 times. The concentration of water-soluble substances increased 1,5 times. P. niemelaei and T. atroviride produce extracellular oxidase of lignolytic complex in the solid-phase cultivation of plant residues. Enzyme activity was 0,15-0,22 u/g.s on sawdust of larch and 0,14-0,18 u/g.s on sawdust of aspen, which is comparable to the phenol oxidase activity of other xylotrophic basidiomycetes (Trametes versicolor, Armillaria mellea s.l., Heterobasidion parviporum).

    Wood-destroying properties of Fomitopsis Pinicola (SW.) P. Karst. From middle Siberia
/ Y. A. Litovka [и др.] // Khimiya Rastitel'nogo Syr'ya. - 2018. - Is. 1. - С. 193-199, DOI 10.14258/jcprm.2018012729 . - ISSN 1029-5151
Аннотация: Presents the results of a research of wood-destroying properties of the basidiomycete Fomitopsis pinicola (Sw.) P. Karst. The strains were isolated in pure culture from fruiting bodies that grew on the Abies sibirica Ledeb, Pinus sylvestris Ledeb, Pinus sibirica Du Tour and Larix sibirica Ledeb in the forests of the Krasnoyarsk Territory (56°09'-56°22' N; 92°10'- 92°58' E). The cultures screened for growth parameters and the dynamics of enzymatic activity during cultivation on cellulose-containing media. The radial growth rate of Siberian strains on the agar medium and plant substrates is 1,1-3,3 mm / day; the growth coefficient is 10-42. All studied cultures synthesize extracellular cellulolytic enzymes that hydrolyze the sodium salt of carboxymethylcellulose. The enzymatic activity is in the range 0,05-0,39 U / ml with a maximum of 7-9 days. The most active strain of Fp5-15 F. pinicola used for bioconversion of coniferous plant substrates under solid-phase culture conditions. The maximum wood-destroying activity observed on pine and larch wood - the mass loss of substrates was 16 and 20%, respectively. On Pinus sylvestris sawdust, the total content of polysaccharides decreased by 1,2 times due to the fermentolysis of the hardly hydrolyzable fraction (a decrease of 1,4 times); the content of lignin substances did not change significantly. On the sawdust of Larix sibirica, the amount of polysaccharides decreased by 1,3 times in comparison with the initial substrate; lig-nin - in 1,2 times. © 2018 Altai State University.
