В статье представлены результаты морфо-биологических наблюдений и биохимических показателей декоративных корневищных многолетников рода Iris L. семейства Iridaceae, произрастающих в условиях Кузбасского ботанического сада. Установлена видоспецифичность по продолжительности вегетации и уровню накопления антиоксидантов в листьях декоративных травянистых многолетников: I. aphylla>I. halophila>I. chrysographes>I. ruthenica>I. pseudacorus. Выявленные перестройки в функционировании антиоксидантной системы ирисов позволяют рассматривать их, как приспособительные и защитные реакции, направленные на их выживание и декоративные качества в окружающей среде. Исследуемые показатели можно использовать в качестве информативного параметра для оценки состояния растений в интродукции. Here we present the results of morphological and biological observations and biochemical parameters of decorative rhizome perennials of the genus Iris L. of the Iridaceae family, growing in the Kuzbass Botanical Garden. We assess the duration of the growing season in relation to particular species. We also estimate the level of antioxidants in the leaves of decorative herbaceous perennials: I. aphylla> I. halophila> I. chrysographis> I. ruthenica> I. pseudacorus. The revealed rearrangements in the functioning of the antioxidant system of irises make it possible to consider them as adaptive and protective reactions aimed at their survival and preservation of decorative qualities. The studied indicators can be used as an informative parameter for assessing plants' state in the introduction.

The paper shows the content of some components of the antioxidant system (ascorbic acid and peroxidase) in the leaves of leguminous plants growing under Pinus sylvestris L. plantings during the growing season. The studies were conducted on the territory of the Kuzbass Botanical Garden (coordinates 55,366186, 86,190160). The objects of the research were Melilotus officinalis and Trifolium repens. The ascorbic acid content was determined by the titrimetric method, peroxidase activity was determined by spectrophotometry. The components activity of the antioxidant system in the leaves of leguminous plants growing under P. sylvestris plantings depended on the species characteristics and the period of plant vegetation. The activity of peroxidase during the growing season in the leaves of Trifolium repens is higher than in the leaves of the Melilotus officinalis. As plants grow and develop, peroxidase levels increase. The content of ascorbic acid in the leaves of leguminous plants revealed an inverse relationship. The studied samples were characterized by the least variability in the content of ascorbic acid, in comparison with the activity of peroxidase. In the Melilotus officinalis, the gap in the variability of ascorbic acid decreased by 1,4 times, compared with Trifolium repens. The closest negative relationship in legumes was found between the activity of peroxidase and organic matter, mobile phosphorus; a positive correlation was noted between peroxidase and the amount of absorbed bases, which indicates a possibility of using the obtained data as diagnostic signs of plant conditions for monitoring natural ecosystems.

Coastal dunes are very dynamic systems, particularly where the coast is rising as a result of isostatic rebound. In those environments, succession proceeds from plants highly tolerant to sand accumulation, salt spray, and low nutrient availability to less disturbance-tolerant and stress-tolerant, more nutrient-demanding, and supposedly more competitive species. In the subarctic, the regional climate exacerbates the stresses imposed by local abiotic conditions on the dunes. I hypothesized that facilitation would be particularly significant on the foredune of subarctic coastal dune systems because of intense stresses (local and regional) and frequent disturbance in the form of sand deposition. Belowground and aboveground plant biomass was sampled at three different periods during the 1990 growing season along transects perpendicular to the shoreline on a coastal dune system in subarctic Quebec (Canada). The three herbaceous perennials found on the foredune (Honckenya peploides, Elymus mollis, and Lathyrus japonicus) were segregated in time during the growing season and in space along the topographical gradient. The biomass of Honckenya, the first species encountered as one progresses from the upper part of the beach towards the foredune ridge, was not correlated to substrate physicochemistry. However, the biomass of Elymus and that of Lathyrus, the next two species to appear along the flank of the foredune, were related to pH, Mg, Na, and Cl (negatively), and to P and Ca (positively). These results suggest variable linkages between substrate physicochemistry and plant species along the foredune, possibly in relation to species-specific tolerance for abiotic conditions and requirements for substrate resources or to microscale influence of the plants themselves on substrate physicochemistry. Removal experiments carried out over 2 years revealed only one significant unidirectional interaction between these three species along the topographical gradient, and little plant control over abiotic variables (e.g., soil temperature, wind velocity, and photosynthetically active radiation). Early primary succession on subarctic coastal dunes (and elsewhere) appears to be under the control of strong limiting abiotic conditions. As plants slowly gain more control over the physical environment, interspecific interactions (positive and negative) may become more significant. Key words: Elymus mollis, facilitation, Honckenya peploides, inhibition, Lathyrus japonicus, removal experiment, succession, tolerance.

The study reports results of research carried out from April to October during 1988–2016 at the Botanical Garden of Petrozavodsk State University (South Karelia, middle taiga subzones). Three introduced species of the genus Larix (Larix sibirica Ledeb., L. leptolepis (Sieb. et Zucc.) Gord, and L. dahurica Turcz. ex Trautv.) were studied. The growth of shoots and needles in different species begins, reaches its culmination, and ends almost simultaneously, differing by no more than one week across the species. L. sibirica shows the highest growth rate. The timing of growth, culmination, and the dynamics of growth of shoots and needles are largely determined by variations in precipitation, temperature, and humidity. The direction and strength of such an effect may vary from year to year. The dates of phenological phases of the Larix species studied here are chiefly determined by the air temperature in the current growing season and the dates of formation of wintering buds in the previous growing season. Bud swelling and opening begins almost simultaneously in the studied species. Most of the other phenological phases begin and end earliest in L. sibirica and latest in L. leptolepis. All the studied species, primarily L. sibirica, are promising for residential landscaping and creation of artificial plant communities in Karelia

In the face of global climate changes, studies of bud burst and bud set phenology in trees are necessary to determine the duration of the growing season of plants, the optimal planting period, and seasonal works to achieve high productivity. The purpose of our study was to investigate bud burst phenology in different poplar and willow clones, what is important for predicting possible responses of woody plants to climate changes. Materials and methods: Bud burst phenology in poplar and willow was monitored both on the plants growing at experimental plot and on potted plants. Open-field plant research was conducted on a test site of fast-growing bioenergy trees in the M.M. Gryshko National Botanical Garden of NAS of Ukraine (Kyiv). Nine most productive poplar and willow clones were selected for the potted experiment. Throughout the growing season, the plants were kept outdoors, and after the seasonal fall of the leaves, the plants were transferred to an unheated storage room with a limited light regime. During spring, bud burst phenology was screened weekly through 45 days according to the 6-scores scale. The studies showed that the poplar plants grown under laboratory conditions demonstrated faster rates of bud burst compared to the willows, while the plants at the experimental plot, on the contrary, shown faster bud burst in the willows comparing to poplar clones. Such effects may be caused by the restricted light regime at the laboratory space what probably had stronger impact on the bud burst in willows, and in the case of open-field plants also by other random environmental factors. In potted conditions, willows demonstrated a tendency for faster flushing of lateral buds, while most poplar clones showed faster apical bud growth under the same conditions.

Abstract Background: The greatest challenge of today’s agriculture is to feed the growing population and restore the natural resources. World over demand of crops in market is more than production. Indian crop production needs to be doubled and just to maintain the present precipitate consumption. . Excessive use of chemical fertilizers causes environmental pollution both at the manufacturing and application sites. It is therefore most necessary to reduce the dependence on chemical inputs in agriculture. This is possible only through eco friendly approaches of farming system. Besides other biotechnological interventions, the arbuscular mycorrhizal fungi could be used as bio inoculants for promotion of growth, development, quality and yield of vegetables that too under an Integrated Plant Growth substances management system. Mycorrhizal fungi are used in conventional agriculture to improve crop production and productivity.Methods: A pot culture was performed at Botanical Garden of School of Studies in Botany, Jiwaji University Gwalior to examine the effect of Glomus hoi on growth and certain biochemical parameters. Plants were raised in triplicates for different mycorrhizal species through the pot culture, containing sterile soil. Plastic pots of 18” × 12”size were used for this purpose. Pots were placed at a sunny place after the seed sowing. And after the seed germination, plants were irrigated as when requiredResults: After germination the inoculated plants along with their controls were be sampled at 30, 60 and 90 days. During sampling it was found that due to AMF symbiosis all growth and biochemical parameters like plant were increased in all AMF treated plants.

Among fruit crops, Rowan is one of the most winter-hardy. In Russia, the predominant varieties are those derived from Sorbus aucuparia. Rowan fruits are used in fresh and dried form, they are valuable in food, dietary, and medicinal terms. The objects of this study were 7 Rowan varieties in the exposition &laquo;Wild fruit plants&raquo; of the Botanical garden-Institute of Volga State University of Technology (Yoshkar-Ola, Mari El Republic). The research was conducted in 2014&ndash;2019. The fruits were collected in the mass maturation phase and weighed in 3 samples of 100 pieces. The yield of air-dry fruits, expressed as a percentage, was obtained by the ratio of the mass of dried fruits to the mass of freshly harvested ones. It was found that the varieties &lsquo;Alaya Krupnaya&rsquo;, &lsquo;Titan&rsquo;, &lsquo;Granatnaya&rsquo;, and &lsquo;Burka&rsquo; are characterized by large fruits. &lsquo;Desertnaya Michurina&rsquo;, &lsquo;Nevezhinskaya&rsquo;, and &lsquo;Doch Kubovoy&rsquo; are small-fruited varieties. The most favorable for fruiting of most varieties were 2016 and 2019 with dry conditions of the growing season. Excessively moistened conditions in 2017 negatively affected the formation of Rowan fruits. The yield of air-dry raw materials was inversely correlated with the weight of fruits. The obtained data can be used in the organization of plantation cultivation of Rowan varieties in the conditions of the Volga-Vyatka region.

Changes of oxidative stress and antioxidant system were studied in leaves of Ginkgo biloba exposed to elevated CO2 and O3 fumigation (2006-2008), and released the gases fumigation for the natural recovery in open-top chambers (OTCs) during the growing season in 2009. Elevated CO2 had no significant effect on hydrogen peroxide (H2O2) and malondialdehyde (MDA) contents, and the activities of antioxidant enzymes in leaves of G. biloba during the gas fumigation in 2008. Elevated O3 increased significantly H2O2 and MDA contents, especially after 90 days of gas fumigation. The adverse effect or damage of elevated O3 on trees during the gas fumigation was also alleviated by the released-O3 exposure during the natural recovery. The antioxidative enzyme including superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) activities showed higher levels under the natural recovery than under the gas fumigation, which may be a helpful response to scavenging reactive oxygen species (ROS). The results also indicated that future alleviating the emissions of CO2 and O3 would differentially affect the antioxidant system in plants.
