Rather large population of this species was found in Siauliai district (northern Lithuania), in the vicinity of Bridai village, on the territory of recultivated former municipal dump. This species can be easily distinguished from other perennial Helianthus species by glabrous stem, long, serrate, alternate leaves on the upper part of the stem and spindle-shaped roots. Supposedly, H. grosseserratus was brought to the area with garden waste or soil used for dump recultivation about 30 years ago and recently it has established in the locality. In the investigated capitula, no developed seeds were found. H. grosseserratus reproduces vegetatively by rhizomes and under favourable conditions can survive for a long time.","PeriodicalId":9098,"journal":{"name":"Botanica Lithuanica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84034620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Teixeira da Silva","doi":"10.2478/botlit-2014-0009","DOIUrl":"https://doi.org/10.2478/botlit-2014-0009","url":null,"abstract":"Abstract The biological and chemical properties of the medicinally important high altitudinal plant Rhododendron anthopogon D. Don were assayed. Extracts at a concentration of 100 mg-ml-1 from leaves and flowers were collectively obtained by employing hot extraction method with different solvents. The antibacterial and antifungal properties were assayed against different clinical bacteria (two Gram+ and six Gram-) and six phytopathogenic fungi. Klebsiella pneumoniae and Salmonella typhimurium were the most inhibited bacteria, while Fusarium eridiforme, a fungus, was highly inhibited. However, all the tested bacteria were resistant to n-hexane and chloroform extracts. Of all the extracts obtained, the ethyl acetate fraction, followed by the hot methanolic extract, was effective against all the pathogenic strains tested. The MIC (minimum inhibitory concentration) and MBC (minimum bactericidal concentration) values of ethyl acetate and aqueous extracts on bacteria ranged from 1.562 mg-ml” 1 to 25.0 mg-ml” 1, whereas MIC and MFC (minimum fungicidal concentration) values of n-hexane and ethyl acetate fractions on fungi varied from 1.562 mg-ml-1 to 12.50 mg-ml-1, which are slightly higher than expected. The extracts showed no activity against Exserohilum turticum and Stenophylum sp. There was a highly significant difference in the zone of inhibition between different extract fractions and bacterial or fungal strains. A preliminary qualitative phyto-chemical assay revealed the presence of polyphenols, reducing compounds, quinones, sterol, triterpenes and fatty acids in leaves and flowers of the test plant. The observed antimicrobial effects are believed to be due to the presence of these compounds. The broad spectrum of activity of the extracts would apparently explain the widespread use of this plant for controlling human pathogenic bacteria and phytopathogenic fungi that widely destroy crops in Nepal. This research reveals R. anthopogon to be a highly promising source of potent antimicrobial drugs that could be used to design therapeutic drugs in the pharmaceutical industry.","PeriodicalId":9098,"journal":{"name":"Botanica Lithuanica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87136830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study was carried out in 2013 and aimed to assess long-term human impact on the structure of plant cover and hydrology of Aukstumala raised bog. On the basis of vegetation assessment (Twinspan analysis), four habitat types were identified: i) active raised bog, ii) degraded raised bog drained by ditches, iii) contact zone of the bog and the peat mining fields and iv) recently burnt areas. The largest anthropogenic impact on vegetation cover was found in the degraded raised bog drained by the ditches and in the burnt area, where the proportion of plant species atypical to ombrotrophic raised bogs was the highest. Water electrical conductivity negatively correlated (r = -0.57) with bog water level, whereas correlation between pH and bog water level was weaker (r = -0.38). Water level in the active raised bog was significantly higher than in the rest three habitat types. Electrical conductivity values in the active raised bog were significantly lower compared to the degraded raised bog and burned area habitats. In order to recreate favourable conditions for peat accumulation and natural functioning of bog ecosystem, mean bog water level should be raised at least up to -32 cm (the optimum water level assigned for most of the typical ombrotrophic species fell into the range of -20 - -32 cm).","PeriodicalId":9098,"journal":{"name":"Botanica Lithuanica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87897700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Investigations on the presence of algal infection mostly involved wild plants and plantation crops of economic interest. Nevertheless, limited studies have examined cultivated ornamental plants for the presence of C. virescens. During the summer and monsoon seasons of 2011 we examined ten leaves of five plants belonging to 86 ornamental plant taxa in 38 families growing in home gardens in Coimbatore, Tamil Nadu, India for the algal presence. Nine of the 86 plant taxa were found to host the algae C. virescens. Although majority of the investigated species are considered as typical hosts of C. vi-rescens, its infection was found only in nine plant species. Although the incidence of the algal leaf spot disease was in general low, there was significant variation in the frequency of occurrence of the algal lesions and the lesion size among the investigated plant taxa and seasons. On plants of five species (Alpinia purpurata, Ficus benjamina, Ficus elastica “Variegata”, Michelia champaca, Polyalthia longifolia), C. virescens was found during both seasons, while infections on the remaining four species (Aglaonema commutatum, Dieffenbachia maculata, Eucalyptus globulus, Syngonium podophyllum) were observed only during the monsoon. The susceptibility of different plant species in a genus and varieties of a species varied suggesting the host influence on the development of infections in addition to variation attributed to the local environmental conditions.","PeriodicalId":9098,"journal":{"name":"Botanica Lithuanica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78257117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effects of foliar application of salicylic acid (SA) and ascorbic acid (AS) during vegetative and reproductive stages at three farmyard manure (FYM) rates (zero (FYM1), 15 (FYM2), 30 (FYM3)t·ha-1) were studied on the growth and yield components of lentil (Lens culinaris Medik.) under supplemental irrigation of semi-arid highland in the north-west of Iran. The results revealed that application of farmyard manure especially at high level could significantly increase the morp-ho-physiological traits such as plant height, first pod height, plant canopy spread, rooting depth, the number of root nodules, ground cover, chlorophyll content and relative water content. Although improving effects of SA and AS on growth parameter were less than FYM, plants treated with SA showed better performance than plants treated with AS. A similar status was observed for grain yield and yield component. So the highest grain yield was recorded at FYM by foliar application of SA. It can be concluded that FYM3 as the most promising manure application rate was adopted to improve both root and total above-ground plant growth. Also this work highlights the importance of exogenous application of growth regulators in lentil cropping systems in semi-arid region with the Mediterranean climate.","PeriodicalId":9098,"journal":{"name":"Botanica Lithuanica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78447278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
