The aim of this study was to investigate the role of willowherb plants in the initial stage of vegetation succession a year after the use of glyphosate. The study was based on the examination of thirteen willowherb specimens collected in the apple orchard of 0.2 ha area in August 2008, one month after glyphosate treatment, and vegetation field investigations in the same orchard in July 2009. The coverage of herb layer, the abundance and life stages of Epilobium plants in twenty plots of 1 m2 in size were investigated. The specimens of willowherbs, which survived the glyphosate application in 2008, were identified as Epilobium ciliatum and E. tetragonum. A year after the glyphosate treatment, the willowherb plants prevailed in the vegetation. One alien (E. ciliatum) and three native (E. hirsutum, E. parviflorum and E. tetragonum) species of willowherb were found. E. ciliatum was the most abundant. This species was characterized by the highest number of reproductive and virginile plants. E. parviflorum and E. tetragonum plants were abundant with a very high proportion of reproductive plants. Only pre-reproductive plants of E. hirsutum occurred in the study plots. The reproductive plants represented more than one third of the total number of willowherb plants. The distribution patterns of willowherb species in the plots were very variable. Abstraktus Kai kurios ožkarožių (Epilobium) rūšys laikomos piktžolėmis ir yra tapusios vis didėjančia žemės ūkio problema. Darbo tikslas buvo nustatyti, kokį vaidmenį atlieka ožkarožių augalai pradinėje augalijos vystymosi fazėje po purškimo glifosatu. Buvo tirti ožkarožių pavyzdžiai, surinkti 2008 metų rugpjūčio mėnesį 0,2 ha ploto obelų sode, praėjus mėnesiui po purškimo. Kitų metų liepos mėnesį tame pačiame sode buvo tirta augalija. Sodo augaliją reprezentuojančiame 100 m2 plote buvo nustatyta rūšių sudėtis ir gausumas. Dvidešimtyje 1 m2 laukelių vertintas žolių dangos projekcinis padengimas, ožkarožių augalų gausumas ir jų vystymosi stadijos. Nustatyta, kad po purškimo išliko tik Epilobium ciliatum ir E. tetragonum augalai. Kitais metais tirto ploto augalinė danga buvo sudaryta iš 18 augalų rūšių, bet didžiausias projekcinis padengimas buvo Epilobium genties augalų. Buvo identifikuotos viena svetimžemė (E. ciliatum) ir trys vietinės floros (E. hirsutum, E. parviflorum and E. tetragonum) rūšys. Gausiausi buvo E. ciliatum augalai. Ši rūšis pasižymėjo ir didžiausiu generatyvinių bei virgininio brandos amžiaus tarpsnio augalų skaičiumi. Didžiąją dalį E. parviflorum ir E. tetragonum augalų sudarė generatyviniai individai. Visi E. hirsutum augalai buvo priešgeneratyvinio brandos amžiaus periodo. Generatyviniai individai sudarė daugiau nei trečdalį visų ožkarožių augalų.

Located near Vilnius city, the habitat of Heracleum sosnowskyi, formerly a natural forest edge has recently been densely occupied by plants of this species. SEM micrographs of abaxial and adaxial surfaces of mericarps obtained from satellite and stem branch umbels of H. sosnowskyi were similar, but morphometrical analysis revealed statistically significant differences in mericarps collected from satellite umbels, which were longer and wider than mericarps from stem branch umbels. The data on longitudinal sections of H. sosnowskyi mericarps clearly showed that embryos of satellite umbels were at later torpedo stage compared to embryos of stem branch umbels, which were at earlier heart stage. These data represent unequal development of the embryos in mericarps from different types of umbels. Such different development can be treated as an adaptation of the invasive plant to occupy the current habitat and survive in the seed bank by allowing the embryo to complete development within a seed and germinate when new conditions permit.

In the cold steppe of the North West of Iran, nutrient management is a crucial component for successful potato production. This study was conducted to determine the effect of different fertilizers on growth, phenological development, tuber yield and tuber qualitative characteristics in two potato cultivars (‘Agria’ and ‘Spirit’). Specific objectives were to assess the effects of nanofertilizers on potato. Fertilizer treatments included: T1 - control (no fertilizer application), T2 - N-P-K chemical bulk fertilizer, T3 - MOG enzymatic bio-fertilizer, T4 - nano-chelated calcium, T5 - nano-chelated zinc+boron and T6 - nano-chelated complete fertilizer. The results indicated that application of nano-chelated Zn+B, complete nanofertilizer and chemical bulk N-P-K significantly increased plant height, the number of stems, main stem diameter and the number of leaves, and also accelerated the row closure (canopy closure). Application of nanofertilizer noticeably decreased the number of days to the initiation of tuberization. The evaluation of tuber yield components revealed that the highest numbers of tuber per plant, mean tuber weight, tuber weight per plant and harvest index were obtained by application of complete nanofertilizer. Comparisons of the cultivars indicated that ‘Agria’ was more responsive than ‘Spirit’ to nutrient managements and showed a more acceptable performance. Nutrient managements significantly affected the qualitative characteristics of tuber; so that the highest dry matter, starch and protein content was recorded for plant grown by complete nanofertilizer. The results of the present experiment agreed with the conclusion that balanced plant nutrition through the efficient nanofertilizers can improve potato productivity.

To detail root gravity sensing in stimulus-free microgravity environment, researchers from the Institute of Botany developed an automatically operating centrifuge “Neris-8” to grow garden cress seedlings and to chemically fix them at the end of the experiments. There was examined behaviour of gravity sensors - amyloplasts within cap cells of roots responding to stimulation by artificial fractional gravity. The static of amyloplasts was determined in roots after continuous growth for 25 h in microgravity, 0.005, 0.02, 0.1 and 1-g environment. The movement kinetics of amyloplasts was studied in roots during the exposition to microgravity after 24-h growth in 1-g environment or conversely. Quantitative study on the patterns of positioning and movement of plastids was performed by light microscopy. The results obtained led us to detail a mode of gravity sensing by roots in which the interactions between moving amyloplasts, cytoplasm and cytoskeleton were discussed.

Three amounts of farmyard manure (FYM) including 0, 10 and 20 t/ha together with foliar growth regulators including 0, salicylic acid (SA), ascorbic acid (ASc) and SA + ASc were used. The results revealed that application of 10 and 20 t/ha farmyard manure significantly increased plant height and the number of lateral stems. However, application of 20 t/ha led to the increase of the number of the main and flowering stems, biomass and essential oil percentage of dragonhead compared to control. The effect of growth regulators on the number of lateral and flowering stems, and biomass was significant: foliar application of SA and ASc separately or in combination increased the number of lateral stems; however, the number of flowering stems and biomass of dragonhead increased only when both growth regulators were used in combination (SA + ASc). The results also indicated that the highest length of inflorescence (13.57 cm) and essential oil yield (41.83 kg/ha), by 31.4 and 126.3% increment, respectively, were observed under foliar application of 20 t/ha farmyard manure together with SA + ASc application compared to the control.

Among 37 alien species recorded in the Reserve, four species are penetrating into natural habitats and threatening their existence. It was ascertained that about half of all species were recorded in meadows and glades of the forests, i.e. in the habitats, which occupy less than 1% of the whole territory. These are also habitats of most extinct and endangered species. Riparian and fontinal black alder woods are the most rich in vascular plant species among forest habitats.","PeriodicalId":9098,"journal":{"name":"Botanica Lithuanica","volume":"176 1","pages":"23 - 48"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79838887","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}

TPC in pomace did not differ significantly between years only in ‘Gretha’ and ‘Northblue’ cultivars; they accumulated stable content of phenolics. The variation in TAC in pomace across seasons was 2–5 times higher than that in TPC. The variations in TPC and TAC in juice across harvesting years were lower than in pomace, but both TPC and TAC in this fraction also differed significantly (p < 0.05) between years in all studied cultivars. The activity of juice and pomace of cultivars against food pathogens was mostly stable and did not show significant differences between harvesting years; the significant correlations were not established between antimicrobial activity of both berries fractions and TPC and TAC in all investigated cultivars. Bacteria were the most susceptible to blueberry juice with Micrococcus spp., Bacillus macerans and Escherichia coli being the most sensitive species. The evaluation of antifungal effect shows that only P. chrysogenum was sensitive to the juice of blueberries, while Aspergillus niger, Cladosporium sphaerosphermum and Penicillium chrysogenum showed resistance to the tested blueberries juice and pomace extracts.","PeriodicalId":9098,"journal":{"name":"Botanica Lithuanica","volume":"38 1","pages":"78 - 86"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76903511","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}
