Full textAbstract:
This is the first confirmed occurrence in Romania of a significant <strong><em>(notho)population</em></strong> of seven hybrids, <strong><em>Anacamptis × timbali </em>nothosubspecies <em>reinhardii </em></strong>(Ugr. ex E.G. Camus) H. Kretzschmar, Eccarius & H. Dietr., 2007, hybrids between two highly divergent species, <strong><em>Anacamptis coriophora </em></strong>(from <em>Anacamptis coriophora</em> group) and <strong><em>Anacamptis palustris</em> subsp. <em>elegans</em> </strong>(from <em>Anacamptis palustris</em> group). The seven hybrids, very likely <strong>F1 generation</strong> plants representing a single <em><strong>interspecific/intrageneric pollination event</strong></em>, were first studied at <strong>Grădiştea Muncelului-Cioclovina Natural Park, Hunedoara County, Romania</strong>. The hybrids were phenotypically intermediate between their parental species in most of the 25 morphometric and 41 morphological characters scored, but significantly, they closely resembled <em>Anacamptis palustris </em>subsp. <em>elegans</em> parent. Additionally, <em><strong>pollination</strong></em> studies were performed. Since the parental species occurred in near proximity (at less than 1 meter distance), we suggest that the production of this hybrid required a minimum travel distance of ca 1-10 meters, by the pollinators and frequent exchange of pollen between the parental species was very likely. The parental species <em>Anacamptis coriophora </em>and the hybrid, which display a considerable synchronicity in their flowering time, were proved to overlap in pollinator community, very successfully sharing the <strong><em>solitary bees</em></strong> belonging to <strong>genus <em>Lasioglossum</em></strong>. The presence of fruits in almost all the hybrids is another proof that they were successfully cross-pollinated. It is clear that even contrasting pollination syndromes such as generalised food deception (in the nectarless <em>Anacamptis palustris</em> subsp. <em>elegans</em>) and generalised food foraging behaviour (in the nectar-producing <em>Anacamptis coriophora</em>) mechanisms are insufficient to fully stop the gene flow between the two species. We set this hybrid population discovery in the context of the recent, expanding evidence of the occurrence of wild species of orchids in Grădiştea Muncelului-Cioclovina Natural Park.

Full textAbstract:
Orchids are among the plants most threatened by anthropic impact and environmental changes. Therefore, all known orchid species are protected in several countries by regional, national and international legislation. Several studies have cast doubts on the effectiveness of legislation to ensure the protection of wild orchids. We assessed the vitality of four orchid populations in a coastal area in Northern Italy, by monitoring the vegetative and reproductive traits of the orchid populations growing both in the protected sites comprising the Natura 2000 network, and in non-protected sites. We also monitored the level of environmental threat to orchid vitality. The early-flowering deceptive species (Ophrys sphegodes and Anacamptis morio) exhibited high vegetative vitality and experienced similar levels of environmental threat in the protected and non-protected areas. However, their reproductive success was strongly jeopardized, probably by a failed pollination that impeded the fruit set. The late-flowering, partially or totally rewarding species (Anacamptis pyramidalis and Anacamptis coriophora) were more strongly impacted by spring mowing and ungulate herbivory and alien species. Only for A. coriophora were the herbivory and alien species invasions lower at the protected vs. non-protected sites, which ensured a higher population vitality at the protected sites. We conclude that the environmental protection in our study area is ineffective for preserving orchids without targeted actions against specific environmental threats.

Представлен краткий конспект родов Anacamptis, Neotinea и Orchis s. str. флоры России и сопредельных государств (в границах бывшего СССР). Рассмотрено 16 видов, многие из которых характеризуются значительной географической изменчивостью и поэтому разделены на подвиды. Приводится определительный ключ, распространение, синонимика и типификация для всех принятых таксонов. В примечаниях при критических видах кратко рассмотрены основные проблемы их систематики. Рассматриваются различные точки зрения на границы родов в связи с новыми молекулярно-филогенетическими данными. Оптимальным является подход к трактовке молекулярных данных, предполагающий расширенное понимание родов Anacamptis и Neotinea (с включением в них части видов Orchis s. l.), и узкое - рода Orchis. Недостаток четких отличительных признаков между родами в новом понимании, послуживший причиной альтернативных классификаций (например, Quentin, 2000; Tyteca, Klein, 2008), считаем нормальным следствием эволюционного процесса, а не показателем неудачно выбранных таксономических границ. Неоднозначным моментом классификации считаем таксономический статус подродов рода Orchis - Orchis и Masculae, который может быть повышен до ранга родов Orchis s. strictiss. и Androrchis, как предлагают некоторые авторы (Tyteca, Klein, 2008; Gamarra et al., 2012). Монотипный род Aceras в любом случае должен быть включен в состав подрода Orchis, так как морфологически очень сходен с видами этого подрода, и между ними известны гибриды в отличие от видов подрода Masculae. На уровне видов наиболее значимыми отличиями от «Флоры европейской части СССР» (и отчасти «Конспекта флоры Кавказа») являются сведение Orchis palustris в подвиды Anacamptis laxiflora и Orchis fragrans - в подвиды Anacamptis coriophora, включение O. collina subsp. chlorotica в состав O. collina subsp. fedtschenkoi, непризнание самостоятельного таксономического статуса O. coriophora subsp. nervulosa, O. mascula subsp. wanjkowii и subsp. pinetorum и другие изменения. Orchis anthropophorum исключается из состава флоры «Восточной Европы». Предложены новые номенклатурные комбинации: Anacamptis laxiflora subsp. palustris, A. laxiflora subsp. elegans, A. collina subsp. fedtschenkoi, A. sect. Phalaenanthus, A. sect. Morianthus. Эндемиков для территории бывшего СССР в этой группе, по нашим данным, нет вопреки «Флоре СССР», приводящей 5 эндемичных видов ( O. chlorotica, O. fedtschenkoi, O. punctulata, O. schelkownikowii, O. viridifusca).

Full textAbstract:
AbstractPollination of deceptive orchids has enabled scientists to understand how these species avoid inbreeding depression by reducing the number of pollinator visits per inflorescence. In rewarding species, which receive a higher rate of visits per plant, geitonogamy is usually higher and therefore the risk of inbreeding increases. In this study, we assess the breeding system of the rewarding orchid A. coriophora, and the spatio-temporal changes in its fitness as well as variation in nectar content after pollination. We found that the species partially selects allogamous pollen if pollinia from the same stalk and other plants arrive to the stigma. Furthermore, when self-pollination occurs, despite successful fructification, seed viability is significantly lower than that of cross-pollinated plants. A. coriophora exhibits spatio-temporal variation in fitness that does not correlate with any plant feature. Moreover, nectar volume is reduced after pollination, but the sugar concentration is maintained. This study emphasizes how essential the pre-zygotic and post-zygotic reproductive barriers are for rewarding orchids to avoid inbreeding depression.

The chemical composition of the essential oil produced by steam distillation of the inflorescences of naturally growing Anacamptis coriophora (L.) R. M. Bateman, Pridgeon & M. W. Chase subsp. fragrans (Pollini) R. M. Bateman, Pridgeon & M. W. Chase (Orchidaceae) from Kroumiria, north-west Tunisia was studied by GC-MS, which led to the identification of 19 volatile components, representing 97% of the oil. The main constituents were methyl-( E)-p-methoxycinnamate (29.3%), 13-heptadecyn-l-ol (18.6%), 2,5-dimethoxybenzyl alcohol (14.1%) and 4-(1,1,3,3-tetramethylbutyl)-phenol (9.0%). DPPH radical scavenging revealed a weak antioxidant activity. In addition, the antiproliferative effects were evaluated on BxPC3 human pancreatic carcinoma cells and on 2008 human ovarian cancer cells showing significant effect. This is the first report of the chemical composition of essential oils obtained from A coriophora subsp. fragrans inflorescences for North Africa. Further studies are needed to understand fully the possible mechanism of action behind the cytotoxic activity of the essential oil.

Romanian flora includes a high diversity of orchids, any with a high conservationist interest, but many 0f themnot yet sufficiently investigated from an ecological, phytosociological or genetic point of view. Phenotypically analysis is also scarce and only a few data have been published in relation to the effects of site factors on the morphological and anatomical characteristics of the family Orchidaceae. This study analyses the variability of two populations of Anacamptis coriophora, based on their coenological affiliations, morphological observations and biometrical measurements. The data were collected from two grassland areas in Romania Stoenesti, Vâlcea County and Cobia, Dâmbovița County. The results showed that both populations are influenced by temperature, light and humidity and develop normally under optimal conditions. In the most favorable conditions encountered in Vâlcea county, orchids offer the splendor of flowers for a long time. Orchids in our country usually bloom in March, sometimes lasting until August, they have a delicate appearance, varied colors and the most diverse perfumes. The information obtained regarding the morphological diversity of the two populations could be suitable for designing strategies for their conservation in both locations.

The volatile fractions from fresh inflorescences of naturally growing orchids Anacamptis coriophora (L.) R. M. Bateman, Pridgeon & M. W. Chase subsp. fragrans (Pollini), Anacamptis pyramidalis (L.) R. Ophrys holosericea (Burm.) Greuter and Serapias vomeracea (Burm. f.) B. were isolated by steam distillation and analyzed by GC/FID and GC/MS. Saturated hydrocarbons were quantified as the major constituents of the volatile fraction (47.87–81.57% of the total essential oil), of which long-chain monounsaturated hydrocarbons accounted from 9.20% to 32.04% of the total essential oil. Double bond position in linear alkenes was highlighted by dimethyl disulfide derivatization and MS fragmentation. Aldehydes (from 3.45 to 18.18% of the total essential oil), alcohols (from 0.19% to 13.48%), terpenes (from 0.98 to 2.50%) and acids (0.30 to 2.57%) were also detected. These volatiles compounds may represent a particular feature of these plant species, playing a critical role in the interaction with pollinators. DPPH assay evaluating the antioxidant activity of the essential oils was carried out, showing a dose-dependent antioxidant activity.

Full textAbstract:
In this study, the seed micromorphologies of eight taxa of Anacamptis, Neotinea and Orchis growing around Edirne province (Turkey) were investigated using light microscopy and scanning electron microscopy (SEM). Slides prepared with glycerin jelly were used for measurements under the light microscope and fine details of seed testae characteristics were observed with SEM. Seeds of the investigated orchid taxa are fusiform shaped and of different shades of brown. Their lengths and widths are different among the taxa and range between 0.263–0.640 mm and 0.118–0.208 mm, respectively. Testa surfaces of Orchis mascula subsp. mascula, O. purpurea subsp. purpurea and O. simia subsp. simia, are smooth while those of Anacamptis coriophora, A. laxiflora subsp. laxiflora, A. morio subsp. morio, A. papilionacea and Neotinea tridentata subsp. tridentata are reticulate. An identification key based on seed morphologies and sizes is suggested for the first time, including testae structures of orchids growing in Edirne province. The overall results of the study showed that morphological structures of orchid’s seeds could be used as diagnostic characters in identification.

Salep orchids have been used as a food for centuries without cultivating but, mainly harvesting from nature. After powdering, their tubers are utilized as hot beverage and in ice-cream industry as a stabilizer. Due to their importance in food industry, it is important to characterize the morphology and chemistry of salep orchids. In this study, it was aimed to determine some morphological (fresh weight, dry weight and dry matter ratio of tubers and the number of tubers required for 1 kg salep powder) and chemical (glucomannan, starch, protein, moisture, ash, nitrogen, phosphorus, calcium, magnesium, potassium, iron, copper, manganese and zinc contents and glucomannan/starch ratio of tubers) properties of 10 salep orchid species from 6 genus namely, Anacamptis pyramidalis, Dactylorhiza romana, Himantoglossum caprinum, Himantoglossum comperianum, Ophrys apifera, Ophrys mammosa, Orchis coriophora, Orchis morio, Orchis tridendata, Serapias vomeracea grown in nature of Black Sea Region of Türkiye. Such a kinds of data is the first and can be beneficial in utilizing the researched species in food industry.
