Opis:
The mycorrhizal status of 24 plant species considered as endemic, endangered in Poland and included in the IUCN Red List of Threatened Plants is reported. Selected plants and rhizosphere soil samples were collected in the Tatra Mts (Western Carpathians). Individuals of seriously threatened taxa were obtained from seeds and inoculated with available AM fungal strains under laboratory conditions. AM colonisation was found in 16 plants; 9 species were of the Arum-type, 4 - Paris and 3 taxa revealed intermediate morphology. The mycelium of the fine endophyte (Glomus tenue) and dark septate fungi (DSE) were observed in the material collected in the field. 20 AMF species (Glomeromycota) found in the rhizosphere of the investigated plants were reported for the first time from the Tatra Mts. The results provide information that might be useful for conservation and restoration programmes of these species. Application of AMF in active plant protection projects is discussed.

Opis:
We present a study of the distribution, ecology and conservation status of Cupressus atlantica, an endemic tree of the High Atlas (Morocco). The main populations of this species grow in a reduced area along the N’Fiss valley in the Central High Atlas and are gradually receding. Particular populations are increasingly fragmented and the total area covered by the cypress woodland has decreased to less than a third of the surface occupied in the 1930s. Overgrazing reduces the woodlands’ regenerative capacity, and the exploitation of the wood, linked to traditional uses by the rural society of the N’Fiss valley, directly reduces the number of trees. Great efforts being made to protect the species by the Haut Commissariat aux Eaux et Forêts are having some effect in recent years.

Opis:
Dionysia involucrata Zaprjag. (Primulaceae) is known as critically endangered endemic species of Hissar Mountains in Tajikistan. It is reported from few localities mainly in Varzob River valley and its tributaries. The species inhabits steep or overhanging faces of granite rocks in narrow river gorges. During the research all known populations of D. involucrata were examined in respect of the habitat conditions and species composition of vegetation plots. We analyzed the population extent of the species in its range in Tajikistan and the main threats in order to assess its conservation status. The detrended correspondence analysis was performed on a matrix of 65 relevés and 49 species (vascular plants and mosses), to classify the phytocoenosis with domination of D. involucrata according to their floristic composition in relation to other petrophytic vegetation units. Using our field data regarding present extent of occurrence and area of occupancy we conclude that the threat category of D. involucrata should be reassessed from critically endangered to endangered. The species shows decline tendency in extent of occurrence, area of occupancy as well as in number of locations. The vegetation plots with domination of D. involucrata have relatively high level of separateness due to different species composition. We define the new association – Dionysietum involucratae – representing chasmophytic vegetation of submontane and montane zone in Middle Asia (ca. 1000–1600 m a.s.l.). The plots of Dionysietum involucratae were found mainly on granite rocks, on very steep or overhanging faces, on southwestern or southern exposition. The association is rather poor in species with inconsiderable contribution of mosses. Despite the diagnostic species, Campanula incanescens, Carex koshewnikowii and Scutellaria hissarica were the most abundant and frequent taxa within the researched patches of vegetation.

Opis:
Amorphophallus titanum niezwykle rzadko obserwowany, endemiczny gatunek Sumatry, jest byliną wykształcająca jeden z największych kwiatostanów świata. Osiągająca ok. 3 m wysokości kolba i ujmująca ją purpurowa pochwa kwiatostanowa, skutecznie wabią zapylające roślinę chrząszcze, błonkówki oraz muchówki, które zwiedzione intensywnym zapachem padliny, ciepłem wydzielanym przez kwiatostan i jego barwą, kierują się ku znajdującym się w jego wnętrzu kwiatom. Mimo zadziwiających rozmiarów dziwidła olbrzymiego, jego biologia nie została dobrze poznana, a powierzchnia okołorównikowych lasów dwuskrzydlcowych Azji Południowo-Wschodniej, w których znajdują się jego nieliczne, naturalne stanowiska, z roku na rok kurczy się. Deszczowe lasy Indonezji i Malezji, będące jednym z głównych centrów różnorodności biologicznej na świecie, wycinane lub wypalane są bowiem pod plantacje olejowca gwinejskiego (Elaeis guineensis), które w samej Indonezji zajmują już ok. 7,7 mln ha.
Amorphophallus titanum, an extremely rare, endemic Sumatran species, is a perennial plant which forms one of the largest inflorescences in the world. Reaching up to approx. 3 m in height, the spadix is surrounded by a purple flower sheath which attracts the pollinators - beetles, hymenoptera and flies. Those, deceived by an intense scent of carrion emitted by the flowers and also by its colour, are lured to the flowers hidden inside the spadix. Despite its remarkable size, A. tutanum's biology has not been well known. The equatorial area of Dipterocarpaceae forests in SE Asia, which is the natural habitat of A. titanium, is dwindling. The Indonesian and Malay rainforests, ones of the main biodiversity hotspots in the world, are being cut and burnt down in order to establish African oil palm (Elaeis guineensis) plantations, which only in Indonesia cover an area of approx. 7,7 mln ha.

Opis:
Genetic diversity of Galium cracoviense, a narrow endemic species, limited to the small area in southern Poland and concentrated on Jurassic limestone outcrops near Częstochowa, was examined using the AFLP marker. Twenty nine individuals from three spatially isolated populations were used for the study. AFLP analysis yielded 157 bands, of which 110 (70%) were polymorphic. The AMOVA analysis revealed a substantially higher variation within populations (89.35%) than among them (10.65%). Values of parameters describing population genetic diversity, such as Shannon index and gene diversity index estimated for each population, were highly similar. The results indicate a high level of genetic polymorphism as well as a high genetic similarity of the isolated populations of G. cracoviense and thus an unconstrained gene flow between them. Based on the results we conclude that additional demographic and genetic studies, are necessary to monitor potential decrease of populations size resulting mainly from the mechanical destruction of plants and their habitats caused by intense tourism. Due to the small general range of occurrence, conservation should include the highest possible number of populations of G. cracoviense.

Opis:
Astragalus nitidiflorus is an endangered legume endemic to the southeast of the Iberian Peninsula. This species develops symbiotic relationships with N-fixing bacteria. However, the problem of isolating its rhizobia has not been solved. Because poor N fixation in plants can be corrected by fertilization, the effect of N-P-K fertilizers on growth, leaf chlorophyll and mineral ions was studied. Plants of A. nitidiflorus were grown in 100%-substrate with different N-P-K fertilizer rates (mg l–1): 1-1-8 (S0), 69-29-35 (SL), 144-43-131 (SM) and 245-58-235 (SH). A treatment with substrate plus soil from the natural habitat and no fertilizers (T0) was included. The reference foliar contents of N, P and K were 42.5, 3.5 and 36.5 mg g–1, respectively. Although the species did not form root nodules when grown in substrate, T0 plants produced active nodules that allowed the plants to grow properly without fertilization. In the absence of nodules, both N fertilization (~144 mg l–1) and Fe fertilization (>12 mg l–1) are vital, as is, to a lesser extent, K fertilization (~75 mg l–1 K2O). The S0 and SL reduced leaf chlorophyll, while SM prevented its degradation.

Opis:
Decalepis hamiltonii Wight & Arn., is a plant species that is endemic to southern parts of India. The aim of this study is to explore the influence of habitat heterogeneity on total phenolics, flavonoids, flavor compound 2-hydroxy-4-methoxy benzaldehyde (2H4MB) and antioxidant potential of tubers. The flavor metabolite 2H4MB was quantified by HPLC using isocratic solvent system (methanol : acetonitrile : water : acetic acid 47 : 10 : 42 : 1) that indicates obvious difference in 2H4MB content of tubers with a maximum of 96.4 ±2.6 and 92.6 ±1.2 mg 100 g–1 dry weight basis (DW) in samples from B.R. Hills and Mysore area of Karnataka, followed by samples from Tirumalai Hills and Kurnool from Andhra Pradesh (89.02 ±0.9 mg 100 g–1 DW), Tamil Nadu (81.6 ±2.4 mg 100 g–1 DW) and Kerala (80.18 ±1.1 mg 100 g–1 DW) of tubers. There was variation in total phenolics, total flavonoids and 2H4MB content of root samples collected from different habitats. Also significant variation in free radical scavenging potential of methanol root extracts was noticed, which is directly proportional to the phenolics, and flavonoids content. Overall, there was 10–16% difference in content of 2H4MB in D. hamiltonii tubers that were collected from different natural habitats, and this habitat heterogeneity has to be considered vital, while using such tubers for edible purposes and food formulations.

Opis:
Rare and endemic plant species represent important components of plant biodiversity which require protection to ensure their sustainable conservation. Cerastium banaticum (Rochel) Heuff. is such an endemic and rare species from Romania, for which the genetic variability of two natural populations was studied by SSR markers. Shannon’s information index revealed low levels of genetic diversity in both populations (I = 0.296). As the first attempt in a conservation program a reproducible micropropagation protocol was established starting from seeds, followed by multiplication, rooting, and ex vitro acclimatization. Among the various plant growth regulators tested the highest multiplication coefficient was achieved on a culture medium with 0.5 mg L -1 6-furfurylaminopurine (K) and 1 mg L -1 α-naphthaleneacetic acid (NAA). On this PGRs concentration a number of 26.6 shoots/individual explant with a mean length of 7.9 cm for new generated shoots was registered. The highest number of roots/indi- vidual initiated shoot was 2.6 and it was recorded on a culture medium with 0.5 mg L -1 2-isopentyl-adenine (2iP) and 0.1 mg L -1 NAA. The outdoor acclimatization was successfully performed in a specially designed rocky area in the ‘Alexandru Borza’ Botanical Garden, Cluj-Napoca (Romania).

The genus Narcissus has several endemic, rare and/or threatened species in the Iberian Peninsula and North Africa. In vitro propagation is a useful tool for threatened plants conservation used in ex situ strategies. Thus, the aim of this work was to study the propagation in vitro of bulb scale explants of five endemic, rare and/or endangered Narcissus species from the Iberian Peninsula, treated with different PGR combinations. Initiation was achieved in half-strength Murashige and Skoog (MS) basal salts and vitamins, 10 g/L sucrose, 500 mg/L casein hydrolysate, 2 mg/L adenine, 10 mg/L glutathione and 5.5 g/L plant agar. In the multiplication phase, the highest bulblet proliferation was obtained in MS medium supplemented with 30 g/L sucrose and the combination of 10 μM 6-Benzylaminopurine (BAP) + 5 μM α-Naphthaleneacetic acid (NAA) in N. alcaracensis, N. eugeniae and N. hedraeanthus; 20 μM BAP + 5 μM NAA in N. jonquilla and N. yepesii. The highest rooting was obtained with 5 μM NAA + 1 μM Indole-3-butyric acid (IBA) for all species (>75%) and more than 80% of the produced bulblets were successfully acclimatized.

Opis:
Allium jesdianum Boiss. & Buhse (Yazdi onion) belonging the family Alliaceae, is an endemic species of Iran that grows wild in the Zagros Mountains range, southwestern Iran. The indigenous people of Iran use the leaves and bulbs of A. jesdianum for the treatment of colds and kidney problems. The bulbs and leaves of various populations of the plant were collected from the alpine regions in Chaharmahal va Bakhtiari province, southwestern Iran. The total phenolic content of ethanol extract was determined by FolinCiocalteu method, the antioxidant activity was evaluated measuring 1,1-diphenyl-2-picrylhydrazyl (DPPH), and the antibacterial activity of the extracts against four bacteria was determined by serial dilution assay. Results indicated that the total phenolic content in ethanol extracts from leaves and bulbs of A. jesdianum ranged between 27.83 to 98.23 mg GAE/g extract. A comparison of all plant extracts in the DPPH assay indicated that ethanol extracts from the populations of A. jesdianum leaves were the most effective free radical scavenging agents. The extracts indicated moderate-to-good inhibitory activities against four bacteria, especially against B. cereus. This finding suggests that the bulbs and leaves of A. jesdianum may be considered a natural source of antioxidants and antimicrobial agents.

Opis:
Autumn daffodil (Sternbergia lutea) is a rare and endangered bulbous plant with yellow flowers grown naturally in Iran and unfortunately for different reasons this plant is at the risk of eradication. Natural multiplication rate of S. lutea is low, thus propagation by chipping method is one inexpensive and simple way to overcome this problem. This research was therefore performed to investigate the propagation method in two experiments. In the first experiment, the effects of some plant growth regulators (PGRs) on induction and regeneration of bulblets from bulb chips (propagules) were evaluated. The propagules were prepared by chipping method and treated with indole butyric acid (IBA), gibberellic acid (GA3), benzyl adenine (BA), kinetin (Kin) and cycocel (CCC) at 100 and 200 mg L–1 concentrations for 2 h and then incubated for two months at 20 ±1°C. At the end of incubation, the results showed the highest percentage of concurrent bulblet + root regeneration (CBRR), number and fresh weight of bulblets related to 100 mg L–1 GA3. The highest percentage of only bulblet regeneration (OBR), only root regeneration (ORR) and non-regeneration were obtained at 200 mg L–1 IBA, 100 mg L–1 Kin and control (distillated water: DW) treatments, respectively. In the second experiment, the bulblets that had rooted from each treatment of the first experiment were planted and the produced bulbs were compared. The results indicated that the highest percentage of bulblet sprouting, bulb number and diameter were found at 100 mg L–1 GA3. Therefore, the application of GA3 with mentioned concentration is appropriate for vegetative propagation of this plant by bulb chipping.

Opis:
The study presents the results of the analysis of development stages of Luronium natans (L.) Raf. depending on water conditions (pH, light, total nitrogen, total phosphorus, organic carbon) in 21 populations in north-western Poland. The fractions of seedlings, juvenile, mature and generative stems, as well as the course of phenological phenomena were determined. Seedlings are sparse and can be found from May to July. Most of them occur in waters ranging from slightly acid to neutral (pH 6.0-7.0) with TP concentrations of 10-20 µg dm-3, TN concentrations < 1.0 mg dm-3 and DOC concentrations of 3.5-5.0 mg dm-3, on a mineral (5-10% OC) and fairly well lit (31-40% PAR) substrate. The generative phase lasts from May to October. The flowering period is between August and mid-September. Only 35.2±9.4% of flowering stems produce fruits. The plant flowers abundantly in waters with total nitrogen concentrations > 1.2 mg dm-3, that is above the level of TN concentrations most favourable to seedlings and both juvenile and mature individuals. TP and DOC concentrations, and light intensity (PAR) do not influence the size of the generative stems fraction in populations. However, sediment structure is of importance in this respect: about 62.9% of stems flower and fruit on a mineral substrate (< 1% OC), whereas only 17.4% do so on an organic one.
