Introduction Experiment

Some results of cultivation of Siberian flora species in culture at the introduction nursery of useful plantsof the Peter the Great Botanical Garden of the BIN RAS, in St. Petersburg have been summed up. All species are classifiedaccording to biological resistance. The analysis of the introduction resistance of plants in Siberia showed that 83.3 % ofthe species adapted well to the new conditions of existence. According to the duration of the introduction experiment,all plants were divided into 5 groups. 37 % falls on the group of species, the life expectancy of which is more than 60years. 45 species of rare and endangered flora of Southern Siberia, grown in culture, have been identified, most of themcan be attributed to resistant (46.7 %) and highly resistant species (31.1 %). The maximum age of these plants in theexperiment reaches 68–84 years. The data obtained can be used to preserve and enrich regional flora and prepare materialfor repatriation work.

The main task of the expeditions was the search for the following species of natural Siberian flora and theintroduction of live plants and seeds to the Botanical Garden named after acad. A. V. Fomin: Cotoneaster mongolicus.C. neo-popvii, C. tjulinae, which are currently presented in our collection. In addition, long-term phenological observations in the conditions of the north-west of Ukraine allowed to isolate new species from the imported material: C. kyachticus.C. logginovii. They are described in the materials of the XIV and XVII conferences “Problems of botany of Southern Siberiaand Mongolia”. A trip to the lake Zun-Torei was dedicated to the search for C. mongolicus. As it turned out later, under theC. mongolicus mother’s plant, we dug up a plant different from the mother’s plant, to which we gave the name C. logginovii.This article provides materials to identify the parents pair in the formation of this hybrid pitchfork. For this purpose,materials of herbarium collections from the vicinity of the lake were used Zun-Torei experienced local botanists, as wellas personal fees. Comparison of the samples allowed to establish their identity with C. mongolicus, as well as to certify it asone of the parents of C. logginovii. Morphological descriptions of annual shoots leaves, flowers, fruits, seeds of three typesof Cotoneasters: C. megalocarpus, C. mongolicus, C. yakuticus; micrographs of endocarp of bones of the previous speciesand C. logginovii, C. melanocarpus, C. uniflorus are given. The herbarium samples of C. mongolicus collected in the areaof the lake Zun-Torey were analyzed. The material is illustrated with photographs of plants introduced in the north-westof Ukraine (Kiev). The introduction of plants by the method of genus complexes by F. N. Rusanov allowed to create theCotoneaster collection, which includes 200 taxa of the genus. In the Botanical Garden named after acad. A .V. Fomin fromthe flora of Siberia preserved 11 species of Cotoneaster: C. commixtus, C. kyachticus. C laxiflorus. C. logginovii, C. lucidus,C. neo-popovii, C. megalocarpus, C. mongolicus, C. tjulinae, C. uniflorus, C. yakuticus.

Жимолость Маака (Lonicera maackii (Rupr.) Maxim.) описана в честь Р.К. Маака (1825–1886), известного натуралиста и исследователя Сибири и Дальнего Востока. Впервые была введена в мировую культуру Императорским Санкт-Петербургским Ботаническим садом (БИН) около 1860 г. В Ботаниче- ском саду Петра Великого известна до 1880 г. и с тех пор представлена посто- янно по настоящее время, без перерывов. Этот вид относится к ряду Maackianae Poyark. ex Nedol. (подсекция Tataricae Rehd., секция Lonicera), в который входит вместе с некоторыми другими представителями рода – L. deflexicalyx Batal., L. prostrata Rehd., L. trichosantha Bureau & Franch. и L. xerocalyx Diels. Cамые старые особи, культивируемые в Санкт-Петербурге, достигли возраста 150 лет. Вид отличается высокой зимостойкостью. В по- следние годы начала XXI в. обмерзание отсутствует или не превышает длины годичного прироста. В прошлом лишь в самые суровые зимы обмерзали побеги более старого возраста. Семена всхожие, и из них выращивается семенное по- томство. Кроме зимостойкости, жимолость Маака ценна своей долговечностью и засухоустойчивостью, а также высокими декоративными качествами. Опыт выращивания её в Ботаническом саду Петра Великого показал, что она хорошо выносит городские условия. В период цветения кустарник покрыт белыми ду- шистыми цветками, во время плодоношения – красными заметными плодами. Декоративность тёмной блестящей листвы сохраняется до глубокой осени. Ягоды долго висят после опадения листьев, сохраняя декоративность до начала зимы. Жимолость Маака в условиях потепления климата сохраняет высокую зимостойкость, репродуктивную способность и декоративные качества. Усыха- ния побегов и распространения болезней и вредителей не отмечено. Вид пер- спективен для озеленения Санкт-Петербурга, устойчив к вредителям и болез- ням и более декоративен, по сравнению с более известной и распространённой Lonicera tatarica L. Культура может быть значительно продвинута на север, прежде всего, на Карельский перешеек и в Южную Карелию. The Maak's honeysuckle (Lonicera maackii (Rupr.) Herd.) was described in honor of R.K. Maack (1825–1886), a well-known naturalist and researcher of Siberia and the Far East. It was first introduced into the world culture by the Imperial St. Pe- tersburg Botanical Garden (BIN) around 1860. In the Peter the Great Botanical Gar- den it is known until 1880 and has since been presented continuously to the present, without interruptions. This species belongs to the ser. Maackianae Pojark. ex Nedol. (subsection Tataricae Rehd., section Lonicera), which includes, along with some other representatives of the genus – L. deflexicalyx Batal., L. prostrata Rehd., L. trichosantha Bureau & Franch. and L. xerocalyx Diels. The oldest specimens, culti- vated in St. Petersburg, have reached the age of 150 years. The species is distin- guished by high winter hardiness. In the last years of the beginning of the 21st centu- ry, frosting is absent or does not exceed the length of a year's growth. In the past, only the harshest winters were frozen by shoots of an older age. Seeds are different, and seed progeny are grown from them. In addition to winter hardiness, Maak's hon- eysuckle is valuable for its durability and drought resistance, as well as high decora- tive qualities. The experience of its growing her in the Botanical Garden of Peter the Great showed that she is well tolerated by urban conditions. During the flowering pe- riod, the shrub is covered with white fragrant flowers, during fruiting, with red, no- ticeable fruits. Decorative dark shiny foliage is preserved until late autumn. And ber- ries hang long after falling leaves, keeping decorativeness before the beginning of winter. Maack's honeysuckle, in conditions of climate warming, maintains high win- ter hardiness, reproductive capacity and decorative qualities. The shrinkage of shoots and the spread of diseases and pests has not been observed. The species is promising for the gardening of St. Petersburg, it is resistant to pests and diseases and is more decorative than the more famous and widespread Lonicera tatarica L. The culture can be significantly advanced to the North, primarily to the Karelian Isthmus and to South Karelia.

Phenological Phases

Background. The study and mobilization of natural flora species in botanical gardens allow the curators to save biological resources of useful plant species, and recommend them for urban landscaping. In the flora of Russia, one species of a woody vine from the genus Aristolochia L. is A. manshuriensis Kom.; it is included in the Red Data Book of Russia.Methods The material for the study was A. macrophylla Lam. and A. manshuriensis from the collection of the Peter the Great Botanical Garden maintained by the Komarov Botanical Institute of the RAS. Winter hardiness was assessed; plant height, stem diameter, and crown diameter were measured. The sizes and age are given according to the state of the plants in the fall of 2017. Seed quality was assessed with due regard to the approved guidelines. X-ray analysis of fruits and seeds was carried out using the methods developed for the use of microfocus radiography for seeds and fruits.Results. A. manshuriensis has been grown in the Peter the Great Botanical Garden since 1909. The first flowering was observed in 1918 and 1919, the first fruiting in 1924. Currently, plants of the third or fourth generation are present in the collection. A. macrophylla has been known in St. Petersburg since 1816. Over a 200-year period of introduction, only flowering was observed. For the first time, fruiting in this species was registered in 2007; since 2014, second-generation plants have been grown. Analysis of the seeds collected in 2016 and 2017 showed that they are viable and of high quality in both species of Aristolochia. These species are winter-hardy, demonstrate rapid growth, and may somewhat vary in the timeframe of the passage of main phenological phases in their seasonal rhythm of development.Conclusion. For laying out plantations, it is better to use seeds. A. macrophylla and A. manshuriensis are promising for wider cultivation and use in vertical landscaping.

The Department of Botany on the Potchefstroom Campus (formerly Potchefstroom University for Christian Higher Education) of the North-West University (NWU) had its centenary in 2020. In this paper we celebrate this milestone by giving an overview of the history of the Department at this  campus, including its recent establishment and expansion on the NWU Mahikeng Campus (formerly the University of North-West). A brief overview is presented of the advances in teaching and research over the years, and the development and relevance of the important plant collections in the botanical garden, two herbaria and the national diatom collection. The main emphasis of this contribution is, however, a reflection on the advancement and significance of research conducted by various disciplines on plant and algae function, diversity and ecological restoration over the years. The different disciplines in Botany at NWU, from the oldest to the more recent, are Plant Taxonomy, Plant Ecophysiology, Terrestrial Plant Ecology, Aquatic Sciences, Urban and Settlement Ecology, Geoecology, and Proteomics. Different aspects contributing to changes occurring in the environment, such as pollution, land degradation, urbanisation, overexploitation of resources and the subsequent effect of these on plant diversity and function are especially addressed in our current research. The results of our research inter alia led to solutions for problems occurring in the landscape and contribute to the well-being of the people using the land and water by restoring important ecosystem services.

Oreochromis mossambicus is currently receiving much attention as a candidater species for aquaculture programs within Southern Africa. This has stimulated interest in its breeding cycle as well as the morphological characteristics of the gonads. Limited information is available on SEM and TEM observations of the male gonads. It is known that the testis of O. mossambicus is a paired, intra-abdominal structure of the lobular type, although further details of its characteristics are not known. Current investigations have shown that spermatids reach full maturity some two months after the female becomes gravid. Throughout the year, the testes contain spermatids at various stages of development although spermiogenesis appears to be maximal during November when spawning occurs. This paper describes the morphological and ultrastructural characteristics of the testes and spermatids.Specimens of this fish were collected at Syferkuil Dam, 8 km north- west of the University of the North over a twelve month period, sacrificed and the testes excised.
