Agar, G., Adiguzel, A., Baris, O., Sengul, M., Gulluce, M., Sahin, F. & Bayrak, O. F. 2006: FAME and RAPD analysis of selected Vicia taxa from eastern Anatolia, Turkey. — Ann. Bot. Fennici 43: 241–249.

Fatty acid (FAs) and RAPD profiles were used to examine phenotypic and genetic relationships among 12 Vicia taxa. All the Vicia taxa were separated based on the presence and composition of 77 different FAs. Eight of the ten decamer primers examined were selected to explore the genetic variation. A total of 156 amplicons in the size range of 125–2500 bp were produced by eight different primers from the twelve Vicia taxa. Even though all Vicia species were differentiated by RAPD profiles, three genetically distinct groups were found among the species tested. This is the first study showing that RAPD and FAME analyses are useful methods for differentiation and classification of Vicia and perhaps other plant species and/or taxa as well.

Iqbal, M. & Ashraf, M. 2006: Wheat seed priming in relation to salt tolerance: growth, yield and levels of free salicylic acid and polyamines. — Ann. Bot. Fennici 43: 250–259.

The exogenous application of cytokinins through seed pre-treatment is reported to be involved in plant tolerance to salt stress. It was hypothesized that cytokinins could regulate the salinity-induced changes in hormonal balance for adequate physiological adaptation to stressful environments in plants. Thus, the present studies aimed to assess the effects of pre-sowing seed treatment with varying levels (100, 150 and 200 mg l–1) of cytokinins, namely kinetin (Kin) and benzylaminopurine (BAP), on growth, yield, and leaves' endogenous levels of salicylic acid and polyamines (putrescine, spermidine and spermine) in two spring wheat (Triticum aestivum) cultivars, MH-97 (salt intolerant) and Inqlab-91 (salt tolerant). The primed and non-primed seeds were sown in a field in which NaCl salinity of 15 dS m–1 was developed. The experiments were conducted during the years 2002 and 2003. Of the different priming agents, Kin was very effective, particularly in improving growth and grain yield in both cultivars. Priming with mild concentration (100 mg l–1) of Kin in the salt intolerant and moderate concentrations (150 mg l–1) of BAP and Kin in the tolerant cultivar increased leaf free salicylic acid under saline conditions. BAP priming increased leaf free polyamines (Spermidine and Spermine) in both cultivars under salt stress. Plants of the salt tolerant cultivar raised from non-primed seeds accumulated more putrescine in the leaves as compared with plants raised from primed seeds. In conclusion, seed priming with moderate concentration of Kin showed a consistent beneficial effect on growth and grain yield in both cultivars under salt stress. The mechanism by which Kin-priming induced salt tolerance in wheat plants remains unclear.

Lanta, V., Mach, J. & Holcová, V. 2006: The effect of dam construction on the restoration succession of spruce mires in the Giant Mountains (Czech Republic). — Ann. Bot. Fennici 43: 260–268.

Spruce mires are rare and endangered plant communities of central and western Europe. In the Czech Republic, they were intensively destroyed and drained during the 1970s. To start the regeneration of spruce mires, palisade dams sealed with peat were used to block draining ditches in the Giant Mountains. Four years after construction of the dams, there were significant differences in vegetation above and below the dams. Vegetation above the dams successfully developed towards plant communities characteristic to spruce mire forests. Below the dams, the colonization by forest floor species continued. These differences indicate that palisade dams effectively retain water and help the regeneration of spruce mire forests. Our results support construction of palisade dams in such habitats.

Ruokolainen, L. & Salo, K. 2006: Differences in performance of four ordination methods on a complex vegetation dataset. — Ann. Bot. Fennici 43: 269–275.

Ordination is a widely used method in describing main relationships of multidimensional data. Properties of different ordination techniques have mostly been tested with simulated data. Although simulations provide valuable information about the behaviour of different methods, they are likely to be too simplistic to be able to completely predict the outcome with real data. We used post-fire vegetation succession data to compare four commonly used ordination techniques: CA (correspondence analysis), DCA (detrended correspondence analysis), PCoA (principal coordinates analysis), and NMDS (non-metric multidimensional scaling). Fire intensity was used as a method-independent criterion for comparing the performance of the different methods. Solutions produced by these methods were compared using Procrustean analysis. According to our results, the compared ordination techniques presented different aspects of the multidimensional species space. In general, metric scaling methods, particularly CA and DCA, were far better in reflecting the main gradient in numerical terms, as compared with NMDS. In contrast, non-metric scaling out-performed metric scaling in graphical terms. We conclude that none of the compared methods is perfect in reflecting a complex vegetation gradient. Also, the difference in their abilities makes it difficult to point out the most suitable method for our data.

Torn, K., Martin, G. & Paalme, T. 2006: Seasonal changes in biomass, elongation growth and primary production rate of Chara tomentosa in the NE Baltic Sea. — Ann. Bot. Fennici 43: 276–283.

The seasonal dynamics of the biomass, elongation growth and primary production rate of the green alga Chara tomentosa were measured in Rame Bay (NE Baltic Sea) during the vegetation period of 2002. The measurements showed extremely high plant height (up to 142 cm) and biomass values (5.2 kg(w.w.) m–2), indicating the importance of C. tomentosa for the whole coastal water ecosystem. The apical part of the thallus grew more intensively from early spring to midsummer. The growth rate of the subapical section was very low during the entire observation period. The plant's diurnal net primary production rate peaked in July (43.4 mgO g(d.w.)–1 24h–1); remarkably lower rates were measured in May and September. The elongation growth and primary production were not correlated with water nutrient concentrations and water temperature. As the active growth of C. tomentosa takes place during a relatively short period at the beginning of summer, the amount of available solar radiation and the temperature levels during this sensitive time can have a significant effect on the community in the same year.

Vignolio, O. R., Fernández, O. N. & Castaño, J. 2006: Responses of Lotus glaber (Leguminosae) cv. Chajá to defoliation in reproductive stage. — Ann. Bot. Fennici 43: 284–287.

Lotus glaber is a herbaceous forage legume, which became naturalized in the Flooding Pampa grasslands (Buenos Aires Province, Argentina). Experiments to evaluate defoliation effects on seed and shoot production were conducted in field conditions in Balcarce (Argentina). Lotus glaber plants were clipped (85% aerial biomass) at the beginning of the flowering period. Clipped plants commenced flowering again 21 days after being cut and compensated the vegetative biomass without affecting the reproduction. Clipped and control plants did not differ in seed number, pods and umbels per plant, mean seed weight and seed viability. Lotus glaber has indeterminate flowering, thus allowing to compensate vegetative and reproductive attributes under clipping conditions. Lotus glaber seed weight stability is important because this attribute is positively related to seedling vigor.

Chen, S.-T., Guan, K.-Y. & Zhou, Z.-K. 2006: A new subgenus of Incarvillea (Bignoniaceae). — Ann. Bot. Fennici 43: 288–290.

Currently four subgenera are recognized in the genus Incarvillea Juss. (Bignoniaceae). Incarvillea subgen. Olgaea S.T. Chen, K.Y. Guan & Z.K. Zhou is proposed here based on morphological and molecular data. Morphologically Olgaea differs from the other subgenera in having paniculate inflorescences, opposite leaves (vs. radical or alternate), calyx teeth flat at base and simple plicae between calyx teeth. Also molecular phylogenetic studies support a separate position for I. olgae Regel.

Jin, X.-H. & Li, H. 2006: Coelogyne tsii and Dendrobium menglaensis (Orchidaceae), two new species from Yunnan, China. — Ann. Bot. Fennici 43: 295–297.

Two new species of Orchidaceae, Coelogyne tsii X.H. Jin & H. Li and Dendrobium menglaensis X.H. Jin & H. Li, are described and illustrated from Yunnan, China. Coelogyne tsii is morphologically reminiscent of C. prolifera, from which it differs in having red and secund flowers, and a midlobe one third of the total length of the lip. Dendrobium menglanensis is similar to D. moschatum, but can be easily distinguished by its complanate stem, 1-flowered inflorescence, smaller flowers and white anther cap.

Suillosporium caricis Kotir. & Saaren. sp. nova is described from Estonia. It grows at bases of living and dying Carex species intermixed with Epithele typhae (Fr.) Pat. The new species is relatively thin, smooth with some hyphal pegs, pale cream-coloured. The hyphal system is monomitic, and cystidial organs are clamped, multi-celled and spores narrowly fusiform, ca. 14–17 x 3.5–4 µm.

Crustoderma efibulatum Kotir. & Saaren. and Hyphodontia incrustata Kotir. & Saaren. are described. The former species deviates from the concept of Crustoderma Parmasto in being clampless and thus reminiscent of some species of Phlebia Fr. The latter species is at first sight reminiscent of Hyphodontia sambuci (Pers.) J. Erikss., but with differently shaped, encrusted basidia. The generic position of both species is somewhat uncertain.

Szelag, Z. 2006: Taxonomic and nomenclatural notes on Hieracium tubulare (Asteraceae) with description of a new species from the Eastern Carpathians. — Ann. Bot. Fennici 43: 310–314.

Hieracium coldei Szelag, a new triploid (2n = 27) species in Hieracium sect. Cernua R. Uechtr. from the Eastern Carpathians in Romania, is described, illustrated and compared with morphologically similar taxa. It grows in relict habitats in crevices of andesite rock in B?ile Tu?nad in the Hargitha Mountains, and is morphologically similar to H. tubulare Nyár. from the Retezat Mountains. Based on morphological characteristics, H. sparsum subsp. tubulare [var.] pseudoporphyriticum Nyár. & Zahn, H. sparsum subsp. chlorocaesioides Nyár. & Zahn, H. sparsum subsp. tubulare f. latifolium Zahn and H. sparsum subsp. tubulare f. subevolutum Zahn were found to be conspecific with H. tubulare s. stricto and are reduced to synonymy. Lectotypes for the names H. tubulare, H. sparsum subsp. chlorocaesioides and H. sparsum subsp. tubulare [var.] pseudoporphyriticum are designated.

Yu, H. 2006: A new combination in Dendrobenthamia (Cornaceae). — Ann. Bot. Fennici 43: 315–316.

The name Dendrobenthamia angustata (Chun) W.P. Fang is invalid since the validly published synonym Cynoxylon elliptica Pojark. predates it, thus the correct name is Dendrobenthamia elliptica (Pojark.) H. Yu, comb. nova.
