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.","PeriodicalId":55127,"journal":{"name":"GAYANA BOTANICA","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80944846","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}

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.","PeriodicalId":55127,"journal":{"name":"GAYANA BOTANICA","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74280176","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}

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.","PeriodicalId":55127,"journal":{"name":"GAYANA BOTANICA","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84201105","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}

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.","PeriodicalId":55127,"journal":{"name":"GAYANA BOTANICA","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88916622","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}
