Abstract Among the 2750 species of the Polish vascular flora, about 500 species are threatened with extinction and 430 of them are strictly protected by national law. The FlorNatur project for the ex situ conservation of the most endangered species was started in 2009. The aim of the project is to collect seeds of 61 species from 161 sites in eastern Poland and store them in the Seed Bank of the Polish Academy of Sciences Botanical Garden - Center for Biological Diversity Conservation in Warsaw- Powsin. A complementary program is being carried out by the Forestry Gene Bank at Kostrzyca in western Poland. Their task is to collect 58 species from 129 natural sites in the western part of Poland. To date, seeds of 31 species from 56 populations have been collected, tested and stored in liquid nitrogen.

A spontaneous intergeneric hybrid of Sorbus and Cotoneaster – Pozdnyakov’s sorbocotoneaster (× Sorbocotoneaster pozdnjakovii Pojark.) is an endemic of the South Yakutia. It is known from the river basin Aldan in the areafrom the city of Tommot to the mouth of the river Uchura and on the Aldan-Amga interfluve. It grows in the undergrowthof sparse pine and larch forests on stony-gravelly limestone slopes. It was first found by L. K. Pozdnyakov, a forester,an employee of the Institute of Forest of the Siberian Branch of the USSR Academy of Sciences, on September 9, 1950,when examining forests on permafrost in Yakutia: “in the area of the confluence of the Aya-Sullalah river into Aldan,105–110 km down the Aldan from Tommot” (from the letter of L. K. Pozdnyakov to A. T. Grevtsova, 1982). The article provides data on the origin of the specimens × Sorbocotoneasters, the morphological description of leaves, flowers, fruits,the peculiarities of growth and development in conditions of Kiev, micrographs of pollen grains, micrographs of theendocarp of fruits of three forms, the beginning of the destruction of the scutellum and hypostyle from the ventral side ina hybrid of the third form. Botanical Garden named after acad. A. V. Fomin of the Taras Shevchenko National Universityof Kiev is the only ex situ conservation site in Eastern Europe of the unique Yakut hybrid × Sorbocotoneaster pozdnjakoviiwith leaves of the 1st, 2nd and 3rd forms.

In this study, we observed the flowering phenology, breeding system, pollination and seed germination of four species of Calligonum (C. calliphysa, C. rubicundum, C. densum and C. ebinuricum) in the Turpan Eremophytes Botanic Garden, China. Our results showed that the species had overlapping flowering phenologies and were pollinated by similar pollination agents. Their breeding systems were self-compatible, and with signs of outbreeding, but not of hybridization with each other; the main isolation mechanism was post-zygotic isolation and they also had high seed germination rates. Therefore, they are suited to ex situ conservation in the Turpan Eremophytes Botanic Garden, and can supply sufficient seeds for renewal populations and the conservation of germplasm resources. Furthermore, these results provide theoretical support for the construction of a national germplasm resource garden of Calligonum, and for the introduction to the garden of other eremophyteplants and their conservation.

Medicinal plants are now under great pressure due to their excessive collection so there is a need to immediate attention for conservation of some important medicinal and red list plants. During the period of 2009-2015 germplasm was collected and introduced in to the Andhra University Botanical Garden. A total of 72 introduced species belonging to 66 genera and 35 families were successfully acclimatized in the botanical garden, included 18 red list plants. After acclimatization all plants are transferred to the garden and special block was maintaining as red list medicinal garden.International Journal of Environment Vol.5(3) 2016, pp.31-42

Conservation seed banks are essential for ex-situ conservation of genetic biodiversity. These institutions are especially relevant for threatened species and play a vital role in their conservation by preserving genetic material. However, samples deposited in the seed banks must germinate when necessary to use them (i.e., recovery plans, etc.). This study uses four accessions of the endemic endangered species from Gran Canaria Island (Canary Islands), Isoplexis isabelliana (Webb & Berthel.) Masf. (Scrophulariaceae). Germination tests were carried out to measure seed viability through time and the possible impact of seed storage on their viability. These accessions have been kept in the seed bank for four months to thirty years under different storage conditions. Germination results differed for seeds after 45 days of exposition using 16 hours light and 8 hours darkness at 17 °C. Accessions kept in the seed bank, independently of storage, showed a high germination percentage (89%). Whereas the accessions with rough storage conditions showed a 0% germination rate. The results highlighted the good state of conservation of the material deposited in the Seed Bank of the Botanical Garden "Viera y Clavijo" and the reliability of the temperature and humidity conditions in which the seeds of I. isabelliana have been stored. We consider these results as momentous since several natural populations of I. isabelliana has been affected by the last forest fire on the island.

AbstractMagnolia sinica, a Critically Endangered tree endemic to Yunnan, China, is one of the 20 plant species with extremely small populations approved by the Yunnan government for urgent rescue action before 2015. Information on the geographical distribution and population size of this species had not previously been reported, hindering effective conservation. We therefore carried out a survey of the literature and of herbarium specimens, followed by a detailed field survey and morphological measurements and observations of surviving individuals. We located 52 individuals in the wild, in eight localities. Two distinguishing morphological characters (tepal colour and tepal number) were revised based on observations of all remaining wild individuals that produced flowers and on one 30-year-old flowering plant in Kunming Botanical Garden. The survival rate of individuals propagated from seed for ex situ conservation at the Garden was 100% over 5 years; of 100 individuals transplanted to each of two reinforcement sites, 20 and 18, respectively, were alive after 6 years. We propose two groups of measures to protect M. sinica: (1) in situ conservation, population monitoring, and public engagement, and (2) ex situ conservation with reinforcement or reintroduction.

One challenge of ex situ conservation is developing propagation methods that promote a high rate of survival and genetic diversity. Developing successful propagation methods is especially important for rare species to prevent their extinction. Clasping warea, Warea amplexifolia (Nutt.) Nutt. (Brassicaceae), and scrub lupine, Lupinus aridorum McFarlin ex Beckner (Fabaceae), are two rare species endemic to imperiled Florida sandhill and scrub habitats, respectively. We tested whether the collection site of seeds, seed stratification temperature, and several propagation methods influenced germination and initial survival of W. amplexifolia and L. aridorum. The collection site of seeds and type of pot influenced percent germination of W. amplexifolia, whereas soaking seeds in water and stratification temperature did not. The site where seeds were collected did not influence germination of L. aridorum and treating seedlings with salicylic acid, nitrogen, or salicylic acid and nitrogen sometimes reduced, but did not increase, initial survival of seedlings. Overall, our results will inform additional experiments on ex situ conservation and may be applicable to other herbs endemic to Florida.

Working group of the Department of Plant Conservation of the National Botanical Garden of Georgia (NBGG) have been participating in the global Millennium Seed Bank Partnership, led by the Royal Botanic Gardens, Kew since 2005. During the 2005-2018 period, within the scope of MSB-1 and MSB-2, seeds and herbarium samples of more than 1750 plant species and interspecific taxa, belonging to 107 families and 483 genera (more than 41% of Georgia’s flora) – 348 endemics of Caucasus and 151 endemics of Georgia, have been secured in the National Seed Bank of Georgia (NSB). Seed Bank data are managed in BRAHMS (Department of Plant Sciences of Oxford University). The collection of wild plant species is accompanied by the comprehensive database of geographical, botanical and habitat information. Later phase involves laboratory treatment and germination/viability testing (at least 500 seeds per species) and the long-term deposition and storage (under -20◦C temperature) at the National Seed Bank of Georgia. The duplicates of seed collection and herbarium vouchers are stored at the Millennium Seed Bank of Royal Botanic Gardens, Kew, UK. Germination capacity and viability of collections in NSB is determined before cold storage of seeds, while at the MSB already banked seeds are tested.Keywords: Seed bank; Ex-situ conservation; Plant diversity; Botanical garden; Genetic resources
