Depending on specific combinations of geoenvironmental factors, the micropopulations of the bluehoneysuckle in the valley of the Kuraika River (Gorny Altai) produced fruits of increased or decreased size and seednumber. The observed 3-fold higher accumulation of biologically active phenols in fruits, accompanied by the respectivedecreased accumulation in leaves, and narrower ratios of certain polyphenol classes in leaves and fruits are considered tobe the plant response to the stressing impact of environmental factors, resulting from the active tectonic processes in thestudied area of the Russian Altai.

Seismically active areas of tectonic faults create specific inhomogeneous living conditions of plant populations and can thereby determine their structure. Studies of the reaction of plant reproductive structures to geoecological anomalies associated with active tectonic processes are practically absent. The aim of this work was to study the variability of the reproductive characteristics of Lonicera caerulea subsp. altaica plants in the local seismic zone of the Altai Mountains. We carried out studies in 2017 in the valley of the Kyzyl-Yaryk river (Altai Republic, Kosh-Agachsky district) (See Fig. 1), which was formed in the junction zone of seismic-generating faults active in the Holocene that are the boundaries of the North Chuy Range, Kurai intermountain basin and Chagan-Uzun massif and separating the Kurai and Chuysky depressions. We isolated 5 micropopulations of the Altai subspecies of blue honeysuckle - L. caerulea subsp. altaica in areas differing in volumetric activity of the radon emanation field (262-1162 Bq / m3) for research. Fifty fruits were selected in each micropopulation of L. caerulea subsp. altaica from 20 plants. We examined the morphometric characteristics and taste of the fruits, the number of full seeds and immature ovules in the fruits, the ratio of the number of full seeds to the total number of seeds and ovules, the correlation between the characters, as well as the seed germination capacity and germination readiness. The taste of the fruits was evaluated by the organoleptic method on a 5-point scale of taste variations based on the degree of bitterness in the fruits. To determine seed germinating capacity and germination readiness, germination was performed in Petri dishes at room temperature. We evaluated germination readiness on the 5th day, where n is the number of seeds and N is the number of seeds germinated during this period. For each micropopulation, we analyzed data for intragroup homogeneity using the χ2 method. Student’s t-test, Fisher’s exact test and one-way ANOVA analysis were used to test statistically significant differences in reproductive characteristics, as well as to assess the correlation between them. The analysis of variance (ANOVA) showed that the values of the Fisher criterion for the length, width, index, weight of the fruit and the number of seeds in them considerably exceed the critical value, which indicates a reliable effect of the place of plant growth on all these parameters at a 95-99% probability level. For individual test micropopulations, significant differences were found in the morphometric characteristics and seed productivity of plant fruits in comparison to the control micropopulation (the area with the lowest level of radon emanation field) (See Fig. 2, 3, 4 and 5). An analysis of the frequency of occurrence of plants with different weight and seed productivity of the fruits from the studied micropopulations showed a shift in the distribution of these parameters towards larger values, compared to the control micropopulation (See Fig. 6). The seeds collected in the control micropopulation were characterized by the least germination (See Fig. 8) and the shortest germination period (See Fig. 9). In the studied population, the average and close degree of correlation between the weight of the fruit and the number of full seeds was established; the reliability of the correlation varied depending on the place of plant growth. Plants in the L. caerulea subsp. altaica in the valley of the Kyzyl-Yaryk river were characterized by high polymorphism of the fruit shape. The frequency of occurrence of plants with oval fruits was significantly lower than in populations of L. caerulea subsp. altaica in other areas of the Altai Mountains. In micropopulations under the influence of a higher level of volumetric activity of subsoil radon, the variety of fruit shapes (See Fig. 3) and their taste variations (See Fig. 7) increased, including an increase in the expression of the recessive trait L. caerulea, the absence of bitter fruits (bitter-free fruits). The correlation between the level of radon emanation and the frequency of occurrence of plants with bitter fruits was significant at p <0.01. The influence of the level of radon emanation on the variability of morphometric characteristics of the fruit, seed productivity, germination and germination energy of the seeds was not significant. The heterogeneity of the population of the L. caerulea subsp. altaica, according to the features of the generative sphere, suggests a possible influence of a complex of factors associated with active tectonic processes on the formation and development of plant reproductive organs.

&lt;p&gt;Central Asia is one of the most tectonically active and orographically diverse regions in the world and is the location of the highest topography on Earth resulting from major plate tectonic collisional events. Yet the role of tectonics versus climate on erosion remains one of the greatest debates of our time. We present the first regional scale analysis of 2526 published low-temperature thermochronometric dates from Central Asia spanning the Altai-Sayan, Tian Shan, Tibet, Pamir, and Himalaya. We compare these dates to tectonic processes (proximity to tectonic boundaries, crustal thickness, seismicity) and state-of-the-art paleoclimate simulations in order to constrain the relative influences of climate and tectonics on the topographic architecture and erosion of Central Asia. Predominance of pre-Cenozoic ages in much of the interior of central Asia suggests that significant topography was created prior to the India-Eurasia collision and implies limited subsequent erosion. Increasingly young cooling ages are associated with increasing proximity to active tectonic boundaries, suggesting a first-order control of tectonics on erosion. However, areas that have been sheltered from significant precipitation for extensive periods of time retain old cooling ages. This suggests that ultimately climate is the great equalizer of erosion. Climate plays a key role by enhancing erosion in areas with developed topography and high precipitation such as the Tian Shan and Altai-Sayan during the Mesozoic and the Himalaya during the Cenozoic. Older thermochronometric dates are associated with sustained aridity following more humid periods.&lt;/p&gt;

The purpose of this paper was a comparative to study population variability of individual and group composition of biologically active phenol compounds in leaves of Lonicera caerulea subsp. pallasii (Ledeb.) Browic. in natural population of south taiga subzone of West-Siberian plain, Altai Mauntains and in conditions of introduction in the forest-steppe of the Novosibirsk Priobye. Chlorogenic acid and its isomers neochlorogenic acid and dicaffeoyl quinic acid, glycozides of luteolin, apigenin and quercetin, apigenin and luteolin in leaf extracts of L. caerulea subsp. pallasii was identified by HPLC-MS. The quantitative variations content of compounds (classes of biologically active polyphenols and their individual components) depending on vegetation conditions have been explored using HPLC. The major components of L. caerulea subsp. pallasii leaves are rutinoside quercetin, chlorogenic acid and dicaffeoyl quinic acid. The content and ratio of the major phenolic compounds and the composition of their minor components varied depending on the location and conditions of plant growth. The content of derivatives of hydroxycinnamic acids and flavonols increased significantly in response to changes in habitat conditions in natural populations and in the introduction into the forest-steppe zone. The flavones are the least variable compounds in plant leaves. The results can be useful in elaboration of practical recommendations for picking medicinal and food plants in different vegetation conditions
