A new taxonomic status is proposed for the fern Hymenophyllum ferrugineum, for which two subspecies are recognized based on morphological and biogeography data. One subspecies is recognized as endemic to Juan Fernandez Archipelago and the other endemic to southern South America. It is also clarified the relationship with Hymenophyllum frankliniae, the morphologically closest species native from New Zealand.

Abstract The paper presents the results of the inventory of lichen-forming, lichenicolous and allied saprobic fungi from the Praviršulio Tyrelis State Nature Reserve. A total of 199 species were recorded, including 183 lichens, eight lichenicolous and eight non-lichenised saprobic fungi. Four lichenised species (Micarea pseudomicrococca, Parmelia serrana, Sclerophora amabilis and Thelocarpon laureri) were reported new to Lithuania. Three protected species, Cetrelia olivetorum, Cladonia parasitica and Hypotrachyna revoluta, were also observed.

Abstract Ammophila arenaria and Leymus arenarius are dune-building grass species native to European seacoasts. The present study aimed to compare growth responses to the sand burial of A. arenaria and L. arenarius from coastal habitats of the Baltic Sea, when the intensity of sand accretion was relatively low under controlled conditions. Plants were grown from seeds collected from natural coastal habitats, transplanted into individual containers, buried in the sand at different depths in the rapid shoot elongation stage, and further cultivated (11 or 9 weeks) in an automated greenhouse. Burial in sand significantly stimulated the growth of shoots of A. arenaria, the effect was earlier at high burial intensities (46 and 60%) and was evident ten days after the start of treatment. Both shoot and root dry mass increased for plants buried at 13%; however, increased burial depth (37, 46 and 60%) resulted in a significant increase in root biomass. In comparison, shoot biomass decreased significantly at the highest burial intensity (60%). For L. arenarius, there was no direct dependence of shoot elongation rate on burial depth. There was a tendency for increased elongation growth and biomass allocation to leaf sheaths despite a decrease in total shoot mass. Most strikingly, root biomass decreased with sand burial in parallel with increased burial depth up to 21% intensity. In conclusion, although both grass species showed a positive shoot growth response to moderate sand burial intensity, differences in individual responses at the morphological and physiological level indicate the existence of different genetically based adaptation strategies.

Abstract Two landraces of rice, AWGUII-04 and IJ-124, were characterised and assessed for phenotypic variability, heritability, genetic advance and modes of inheritance of some primary yield and drought-tolerance traits. The target traits for yield were a percentage of filled spikelets, plant form, tillering, and for drought tolerance, leaf rolling, ratooning and maturity. This study was carried out to help both breeders and farmers make a wise choice when carrying out hybridisation and on the field. Hybridisation produced three F1 hybrids that were advanced to F2 generation. Quantitative and qualitative vegetative and reproductive data were taken from each F2 population. The results obtained showed high heritability (62–100%) in all the thirty-eight vegetative and reproductive traits. The genetic advance was high (> 20%) in all the target traits except for leaf rolling. The traits segregated in the following ratio: plant growth form – 9:6:1; the percentage of filled spikelets – 13:3; ratooning – 3:1; maturity – 15:1; the number of tillers – 15:1 and leaf rolling – 15:1. The high heritability of the above traits makes them highly dependable for rice crop improvement.

Abstract Start codon targeted polymorphism (SCoT), a novel and gene-targeted marker, has recently become the marker of choice in genetic diversity studies. In the present study, 31 SCoT primers were tested for their suitability in the genetic analysis of 21 coffee genotypes representing 18 species. A total of 647 distinct PCR amplified fragments were produced with a mean of 20.9 fragments per primer and 80.80% of which were polymorphic. The polymorphic information content of SCoT primers ranged from 0.16 to 0.86, with a mean value of 0.63. Resolving power ranged from 6.19 to 28.29, with a mean value of 20.2. Species-specific unique PCR amplified fragments were identified for 16 species, which could be used as genetic fingerprints. The genetic similarity among various coffee species calculated using the Dice similarity coefficient ranged between 0.60 and 0.89. The dendrogram constructed using the unweighted pair group of arithmetic means (UPGMA) clustered the 21 coffee genotypes into two major groups. The study revealed that Coffea jenkinsii, an indigenous species from India, showed the highest similarity with C. arabica, which is of Ethiopian origin. The results proved the suitability of SCoT markers in genetic analysis of coffee genotypes.
起始密码子靶向多态性(Start codon targeted polymorphism, SCoT)是一种新型的基因靶向标记，近年来已成为遗传多样性研究的首选标记。本研究对31条SCoT引物在咖啡18种21个基因型遗传分析中的适用性进行了测试。共扩增出647个不同片段，平均每个引物20.9个片段，其中80.80%为多态性片段。SCoT引物的多态性信息含量范围为0.16 ~ 0.86，平均值为0.63。分辨率为6.19 ~ 28.29，平均值为20.2。对16个品种进行了独特的PCR扩增，可作为遗传指纹。用Dice相似系数计算不同咖啡品种间的遗传相似度在0.60 ~ 0.89之间。利用UPGMA (unweighted pair group of arithmetic means)构建的树状图将21个咖啡基因型分为两大类群。研究表明，来自印度的本土物种咖啡(Coffea jenkinsii)与埃塞俄比亚原产地的阿拉比卡咖啡(C. arabica)的相似性最高。结果证明了SCoT标记在咖啡基因型遗传分析中的适用性。

Abstract We newly found a collection of the Poaceae specimens deposited at the Herbarium of Vilnius University (WI), collected by Povilas Snarskis mainly from eastern Lithuania in 1943–1960. The collection consisted of 67 herbarium sheets representing 28 species, including endangered species Glyceria lithuanica. The collection provided new data on abnormal growth forms of common Lithuanian grasses and the distribution of rare and endangered Poaceae species in eastern and southern Lithuania. The discovered Glyceria lithuanica specimen is the oldest of all known records of the species in Lithuania.

Abstract Performing a thorough inventory of alien plant species in the southern part of Lithuania, we found twelve alien plant species previously not registered in the country: Aruncus dioicus, Buxus sempervirens, Clematis vitalba, Clematis recta, Colutea arborescens, Erechtites hieraciifolius, Erigeron strigosus, Euphorbia marginata, Genista sagittalis, Lathyrus latifolius, Sempervivum arachnoideum and Silphium perfoliatum. All newly recorded alien species, except Erechtites hieraciifolius and possibly Genista sagittalis, have been introduced intentionally and escaped from cultivation. Ten species currently occur as casuals, whereas Colutea arborescens and Genista sagittalis are locally naturalised. Naturalisation of Buxus sempervirens and Euphorbia marginata in the foreseen future is unlikely in Lithuania, naturalisation of Aruncus dioicus, Sempervivum arachnoideum and Silphium perfoliatum is possible. In contrast, naturalisation of the other five species is expected in the nearest future. Invasion of seven analysed alien species is unlikely in Lithuania, whereas Clematis vitalba, Colutea arborescens, Erechtites hieraciifolius, Erigeron strigosus, Lathyrus latifolius have the potential to become invasive in the country. Therefore, their reproduction and spread should be monitored, and measures for prevention of their invasion should be applied, if necessary.
