“…The morphological and anatomical structures of the heteromorphic leaves of P. euphratica , such as the LA, LT, LDW, and PT, increased with increasing diameter class, and all correlated significantly with the diameters, at breast height, at different developmental stages. With age, the factor of heterogeneity of microenvironments and the factor of competition were more strongly pronounced [ 14 ]. The results of this study were similar to those for P. euphratica .…”

“…The leaf is the organ most easily affected by environmental changes and can best reflect the functions of plants and their adaptability to the environment [ 5 , 10 , 11 , 12 ]. As they are the main carbon source of plants, changes in functional traits of leaves play an irreplaceable role in adapting to environmental stress [ 13 , 14 , 15 , 16 ]. Regardless of gymnosperms or angiosperms [ 17 , 18 , 19 , 20 ], specific leaf weight increases with increasing tree age, which may be due to the vulnerability of the leaves of older trees to water stress [ 21 , 22 , 23 ].…”

Populus pruinosa Schrenk has the biological characteristics of heteromorphic leaves and is a pioneer species for wind prevention and sand fixation. The functions of heteromorphic leaves at different developmental stages and canopy heights of P. pruinosa are unclear. To clarify how developmental stages and canopy height affect the functional characteristics of leaves, this study evaluated the morphological anatomical structures and the physiological indicators of leaves at 2, 4, 6, 8, 10, and 12 m. The relationships of functional traits to the developmental stages and canopy heights of leaves were also analyzed. The results showed that blade length (BL), blade width (BW), leaf area (LA), leaf dry weight (LDW), leaf thickness (LT), palisade tissue thickness (PT), net photosynthetic rate (Pn), stomatal conductance (Gs), proline (Pro), and malondialdehyde (MDA) content increased with progressing developmental stages. BL, BW, LA, leaf dry weight, LT, PT, Pn, Gs, Pro, and the contents of MDA, indoleacetic acid, and zeatin riboside had significant positive correlations with canopy heights of leaves and their developmental stages. The morphological structures and physiological characteristics of P. pruinosa leaves showed more evident xeric structural characteristics and higher photosynthetic capacity with increasing canopy height and progressive developmental stages. Resource utilization efficiency and the defense ability against environmental stresses were improved through mutual regulation of each functional trait.

“…There were several different types of these forests, including fir-spruce forests with large ferns and goutweed in the grass layer (Site 1), fir-spruce-moss forests with different sedge species (Site 2), spruce-moss forests with small ferns (Site 3), fir forests with horsetail, wood sorrel, and goutweed (Site 4), and larch-moss forests with sphagnum (Site 5). Earlier, a more thorough explanation of forests was given [10,11].…”

The correlation between the yield of Siberian spruce (Picea obovata Ledeb.) and Siberian fir (Abies sibirica Ledeb.) cones and radial wood increments was examined using long-term data (47 years) from direct observations. Broad-leaved coniferous woods of the Ufa Plateau (PreUral), which are located inside the Ufa River's water protection zone, make up the special polygon where the research was conducted. According to the experiments, there was no correlation with the yield of cones and the radial increment of wood, either positive or negative. Simultaneously, it was discovered that there is a rise in the radial increment of timber wood with an increase in the number of spruce and fir cones in the climatic circumstances of a particular year. The maximum growth of the plant's vegetative mass, in this case, the radial growth of the timber wood, is shown in the year with the highest cone output. Consequently, fir and spruce in this area have the effect of reversing reproductive effort.

The article presents the results of the search for microsatellite or simple sequence repeat (SSR) loci with tri-, tetra-, penta- and hexanucleotide tandem repeat motifs in the draft de novo assembly of the Siberian fir (Abies sibirica Ledeb.) genome and the development of convenient relatively highly and moderately polymorphic markers that can be easily genotyped even by simple gel electrophoresis. In total, 64 pairs of oligonucleotide polymerase chain reaction (PCR) primers for 32 detected microsatellite loci were designed and tested. Based on the testing results, 10 most promising polymorphic loci were selected and genotyped in eight natural populations of Siberian fir. Homologous microsatellite loci in the genome of European silver fir (Abies alba Mill.) were also identified by mapping Siberian fir contigs, containing SSR loci to the European silver fir genome assembly. A multiplex panel of 14 universal microsatellite loci was developed and genotyped in samples from four natural populations of A. alba and a small sample of eight Nordmann fir (Abies nordmanniana (Steven) Spach) trees.
