{"title":"Germination of 10 midland plant species from the eastern Mediterranean Basin: effects of smoke, syringaldehyde, karrikinolide and cyanohydrin","authors":"Şükrü Serter Çatav, Kenan Akbaş, Yaren Fulya Kaplan, Ceren Kızıl, Betül Bürün","doi":"10.1111/njb.04457","DOIUrl":"https://doi.org/10.1111/njb.04457","url":null,"abstract":"The beneficial effects of smoke and its constituents, karrikinolide (KAR1) and cyanohydrin glyceronitrile, on the germination of Mediterranean lowland species are well‐documented. However, very little is known about the role of these signals on the germination of plants at higher altitudes. In addition, lignin‐derived chemicals, such as syringaldehyde (SAL), have recently been proposed as overlooked cues for smoke‐induced germination. To address these gaps in the literature, we investigated the effects of smoke‐water and SAL on the germination of 10 midland species growing on serpentine soils. We also sought to determine whether SAL interacts with KAR1 and/or mandelonitrile (MAN, a cyanohydrin) to enhance seed germination. The results show that smoke‐water significantly improved the germination of three species (Barbarea duralii, Digitalis cariensis and Turritis laxa). SAL, on the other hand, had no positive effect on the germination of the 10 species tested. Furthermore, three smoke‐sensitive species and Verbascum cariense responded to KAR1 and/or MAN. Finally, SAL did not exert any synergistic effects on germination in interaction with KAR1 and MAN. In conclusion, we provide evidence that smoke is an important germination cue also for Mediterranean midland species. Moreover, SAL did not play a role in stimulating germination in smoke‐sensitive species, either independently or in combination with other smoke chemicals.","PeriodicalId":54716,"journal":{"name":"Nordic Journal of Botany","volume":"26 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141771694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Corylifolii, primarily in Sweden, using DNA microsatellites. The results show that the material can be divided into three species: R. wahlbergii s.s. which occurs along the Swedish coast from Bohuslän to Uppland, R. nordicus which occurs on the western coast all the way south to north‐western Skåne, and a previously unrecognized taxon which we here describe as R. wahlbergioides. The latter has scattered localities in Halland, Skåne, Blekinge, Öland and Småland, but is common around Kivik in Skåne and Kalmar in Småland. It is characterised by leaves that are without felt underneath, terminal leaflets with a somewhat more triangular shape and coarser serration than those of R. wahlbergii and also has more glands on the stem and the inflorescence. In the northern part of the distribution, R. nordicus is easily distinguished morphologically from R. wahlbergii, e.g. by a strong tendency to form 7‐foliolate leaves, but in Skåne and Halland, the two species are harder to distinguish. Still, genetically R. nordicus is more similar to R. sordirosanthus than to R. wahlbergii s.s.","PeriodicalId":54716,"journal":{"name":"Nordic Journal of Botany","volume":"36 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141510852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study describes the long‐term ruderal plant species distributions along the ‘Rallarvägen' in Abisko, subarctic Sweden. This trail currently serves as a hiking trail but was initially created as a construction road for a railroad from 1898 to 1903 and is paralleled by the E10 Highway since 1982.Using vegetation and climate data from 1903, 1913, 1983, and 2021, we found that warm‐adapted ruderal plant species were common along the Rallarvägen shortly after railroad construction in the early 20th century. Interestingly, many of these native and non‐native ruderals with relatively high temperature affinity that were present in 1903 and 1913 have since disappeared and have not reappeared, despite the substantial increase in regional temperature in recent decades.In addition, the historical disturbances have had long‐lasting effects on the current spatial distribution of the ruderal vegetation. Most ruderals still reside close to the railroad tracks and are progressively filtered out with increasing distance from anthropogenically disturbed introductory points, such as train stations, where they peak in species richness – a process we term ‘horizontal directional ecological filtering', in parallel to the established concept of ‘directional ecological filtering' along elevational gradients.The historical record of ruderal plant species in the region, influenced by a century‐old railroad construction, emphasizes the importance of knowing a system's disturbance history for understanding current vegetation dynamics and anticipating its future in a changing climate.","PeriodicalId":54716,"journal":{"name":"Nordic Journal of Botany","volume":"203 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141510814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
