The results of studies in 2019-2022 of a new medicinal plant for the flora of Russia Anemarrhena asphodeloides are presented. In the conditions of the VILAR Botanical Garden, all phenological phases are observed. However, the onset of generative phases in Anemarrhena asphodeloides occurs a month later than in nature. So, flowering does not begin in June, but it occurs in the second half of July. The beginning of seed ripening is noted not in August but at the end of September. In addition, plants of Anemarrhena asphodeloides during introduction (zone of excessive moisture) reach a greater height (up to 120 cm) than in natural dry conditions (up to 100 cm). It is shown that during spring sowing, Anemarrhena asphodeloides individuals finish their vegetation in the first year of life in the rosette phase with a height of 12.8-25.7 cm (3-8 leaves). In the second year of life, the generative phase is observed in 62 % of individuals, and in the third year it occurs in 64.5 % of specimens. The average weight of air-dry rhizomes with roots is 14,9 ± 3,5 g/individuals in three-year-olds, and 18,4 ± 4,1 g/individuals in four-year-olds.

In recent years, environmental problems associated with the intensive development of industry, agriculture, and the rapid development of cities have been the most frequently discussed environmental problems in the world. Every year hundreds of thousands of tons of pollutants, including heavy metals, get into the atmosphere, soil, water and other environmental objects. Heavy metals enter the human body with plant products and poison the body. Heavy metals from the environment migrate to plant organs and tissues. It is necessary to find ways to detoxify soils from heavy metals. The article presents the results of the experiment at the biopolygon of the Federal State Budgetary Educational Institution of Higher Education Krasnoyarsk Agrarian University. As a result of the study, we determined the distribution of lead on the organs of mustard and rapeseed.

Phlox breeding in the Siberian Botanical Garden of Tomsk State University was started in 1949, after a 50-year break it was resumed in 2005. The purpose of the selection study of Phlox paniculata in the Siberian Botanical Garden of Tomsk State University is to obtain new highly decorative varieties that are resistant to the conditions of the subzone of the southern taiga of Western Siberia. The production of hybrids has a significant scientific basis and is the result of many years of studying reproductive biology, ornamental characteristics and resistance of varieties. To obtain hybrids in the Siberian Botanical Garden, directional crossing of varieties, obtaining seedlings from seeds with free pollination for collections and in a limited group of varieties, and selecting «random» seedlings are used. With directed pollination of varieties, the fruit set ranged from 15 to 69 %, the percentage of fruit set increases when pollinated with a mixture of three varieties. A partial transfer of decorative traits from parent varieties was established, however, the high variability of the transferred characteristics does not allow us to identify clear patterns at this stage of the study. Phlox hybrids bred in the Siberian Botanical Garden are first of all selected for resistance to diseases and abiotic conditions of the Siberian region, then for decorative qualities. The article contains a description of six hybrids obtained in the Siberian Botanical Garden, promising for registration as new varieties.

The article considers the results of biochemical studies of chlorophyll content in leaves of birch growing in different conditions in the city of Biysk: control, parks, squares, highways, petrol stations, factories, thermal power plants. In park areas, compared with the control, the content of chlorophylls a and b and the a / b ratio are lower. The best conditions for the growth of birch trees (closeness of crowns, distance from highways, and lower frequency of attendance) contribute to an increase in the content of chlorophyll a and b in the leaves. The sparse location of trees in squares and their intensive visits, emissions from industrial enterprises, cars and thermal power plants lead to a decrease in the content of chlorophyll a and b in the leaves. Regardless of the growing conditions, a regular increase in the content of chlorophyll a is observed during the growing season. A change in the content of chlorophyll a in birch leaves has been revealed; in the city of Biysk, it is changing downward in the following row of growing places: control -> parks -> squares -> highways -> petrol stations -> factories -> CHP. In dynamics by month, a slight increase in the concentration of chlorophylls in July was detected in all places of birch growth, and then its decrease in August.
文章探讨了对生长在比伊斯克市不同条件下（对照区、公园、广场、高速公路、加油站、工厂、热电厂）的桦树叶片中叶绿素含量的生化研究结果。在公园地区，与对照组相比，叶绿素 a 和 b 的含量以及 a / b 比率都较低。桦树生长的最佳条件（树冠紧密、远离高速公路、出勤频率较低）有助于叶片中叶绿素 a 和 b 含量的增加。树木在广场上的稀疏位置、密集的光顾、工业企业、汽车和火力发电厂的排放物会导致叶片中叶绿素 a 和 b 的含量减少。无论生长条件如何，叶绿素 a 的含量在生长季节都会有规律地增加。桦树叶片中叶绿素 a 含量的变化已经显现；在比伊斯克市，叶绿素 a 含量在以下生长区域向下变化：控制区 -> 公园 -> 广场 -> 高速公路 -> 加油站 -> 工厂 -> 热电联产。在各月的动态变化中，所有桦树生长地的叶绿素浓度在 7 月份都略有上升，然后在 8 月份有所下降。

Camellia dalatensis is a small tree with yellow flowers in the genus Camellia L. (Theaceae). The species is found in a single in Dalat, southern Vietnam. It is known that the Da Lat Plateau has suffered from habitat loss, degradation and fragmentation in places, and deforestation is directly impacting the range of C. dalatensis. The species is listed as Critically Endangered (CR). To provide an appropriate method for the conservation and sustainable development of this species, the study experimented with air layering and planting in their habitat (in situ). An ex situ experiment for C. dalatensis with several other species was also performed to assess their adaptability. The results showed that the average rooting time was from 3.5-4 months, the rooting rate of air layering was 78.89 % and the survival rate after planting was 96.06 %. Plants were replanted grow well in the habitat of the original population. In a new environment, the survival rate of C. dalatensis is lower than that of other species of the same genus, only 17.14 %. The surviving plants have not yet shown the ability to grow. Thus, at this time, in situ conservation method for C. dalatensis is appropriate.
大叻山茶（Camellia dalatensis）是山茶科山茶属的一种小乔木，开黄色花。该物种仅分布于越南南部的大叻。众所周知，大叻高原的一些地方出现了栖息地丧失、退化和支离破碎的情况，森林砍伐直接影响了山茶花的分布范围。该物种被列为极度濒危物种（CR）。为了提供保护和可持续发展该物种的适当方法，该研究在其栖息地（原生境）进行了空气分层和种植实验。此外，还对 C. dalatensis 和其他几个物种进行了异地实验，以评估其适应性。结果表明，平均生根时间为 3.5-4 个月，空气分层的生根率为 78.89%，种植后的成活率为 96.06%。移栽的植物在原种群的栖息地生长良好。在新环境中，C. dalatensis 的成活率低于同属的其他物种，仅为 17.14%。存活下来的植物尚未显示出生长能力。因此，目前原地保护 C. dalatensis 的方法是合适的。

Between 2013 and 2020, 47 communities with seven species of the genus Delphinium were studied on the territory of 12 regions of the southeast of European Russia. The analysis of habitats by vegetation cover using the ecological scales of L. G. Ramensky showed that soils under communities with species of the genus Delpinium are often quite rich and very slightly alluvial. D. subcuneatum communities grow in habitats with the highest moisture-meadow-steppe (moist-steppe) and wet-meadow habitats; communities of D. duhmbergii grow in less humid habitats with dry-meadow (and fresh-meadow) moisture; with dry-meadow (and fresh-meadow) and meadow-steppe (moist-steppe) humidification - communities of D. dictyocarpum, D. litwinowii, and D. pubiflorum; in meadow-steppe (moist-steppe) humidification, communities of D. sergii. D. puniceum communities grow in the least moisture-provided habitats, with moisture ranging from dry-steppe and middle-steppe to semi-desert (desert-steppe). The biomorphological composition of communities with species of the genus Delphinium is dominated by hemicryptophytes, among which, the most numerous are tap-rooted, short-rhizomatous, and long-rhizomatous. The composition of cenomorphs reflects the confinement of communities with the majority of Delphinium species presented in the study to the forest-steppe zone, and communities with D. sergii and D. puniceum - to the steppe and semi-desert zone. In communities, the first place among trophomorphs is occupied by mesotrophs, and the second by megatrophs. The spectrum of hygromorphs is quite wide and includes species from xerophytes to ultrahygrophytes, however, xerophytes, mesoxerophytes, xeromesophytes, and mesophytes are the predominant groups most often. Judging by the predominance of heliophytes among heliomorphs, communities with all studied species of the genus Delphinium prefer open spaces. The spectrum of thermomorphs of all studied communities is dominated by mesotherms, for which the ecological optimum coincides with a moderate heat supply regime.
2013 年至 2020 年期间，在欧洲俄罗斯东南部 12 个地区的领土上研究了 47 个拥有 7 个 Delphinium 属物种的群落。使用拉缅斯基（L. G. Ramensky）的生态尺度对栖息地的植被覆盖率进行的分析表明，在有德尔菲尼姆属物种的群落下，土壤通常相当肥沃，且极少冲积。 subcuneatum 群落生长在湿度最高的生境--草甸草原（湿润草原）和湿草甸生境；D.duhmbergii 群落生长在干草甸（和新鲜草甸）湿度较低的生境中；在干草甸（和新鲜草甸）和草甸草原（湿润草原）湿度较高的生境中，生长着 D. dictyocarpum、D. litwinowii 和 D. pubiflorum 群落；在草甸草原（湿润草原）湿度较高的生境中，生长着 D. sergii 群落。puniceum 群落生长在湿度最低的生境中，湿度范围从干草原、中草原到半荒漠（荒漠草原）。德尔菲尼亚属物种群落的生物形态组成以半隐生植物为主，其中最多的是直根型、短根瘤型和长根瘤型。蕨类植物的组成反映了群落的局限性，研究中出现的大多数 Delphinium 种类都在森林-草原区，而 D. sergii 和 D. puniceum 的群落则在草原和半荒漠区。在群落中，中养型营养体占第一位，巨养型营养体占第二位。营养体的范围很广，包括从旱生植物到超营养体，但旱生植物、中旱生植物、旱生植物和中生植物是最常见的主要群落。从日光叶植物在日光形态植物中占优势的情况来看，所有研究过的 Delphinium 属物种的群落都喜欢开阔地。在所有研究群落的热形态谱系中，中温植物占主导地位，它们的生态最佳状态与适度的热供应制度相吻合。
