  1. 1. Multi-environment Screening of Timothy (Phleum pratense) Breeding Material for Better Forage Yield in Sweden.

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Author : Ibrahim Issa; [2022]
    Keywords : Phleum pratense; Multi-Environment; Forage yield; Sweden; Genotype-by-environment interaction Swedish;

    Abstract : Timothy (Phleum pratense) is one of the most widely used forage crops in hay and pasture grass mixtures in Nordic countries; it’s also used in areas where it is one of the top forage crops harvested high yield, especially in boreal climates. There hasn’t been any large-scale breeding of Timothy to develop varieties that are adapted for Swedish climate and standards, which is surprising given that Timothy is the main forage crop used in Sweden.

  3. 2. Biodegradation Experiments of Polymeric Materials: Monitoring and Analysis

    University essay from KTH/Fiber- och polymerteknologi

    Author : Sini Ojala; [2021]
    Keywords : Biodegradation; Composting; Differential scanning calorimetry DSC ; Fourier Transform Infra-Red FTIR spectroscopy; Natural Environment; Open environment; Tensile test; Biologisk nedbrytning; Differential skannings kalorimetri DSK ; Dragprovning; Fourier Transformer Infra-Röd FTIR spektroskopi; Kompostering; Naturlig miljö; Öppen miljö;

    Abstract : Plastskräp har blivit ett global problem på grund av nedskräpning och otillräcklig avfallshantering. Användning av biologiskt nedbrytbart material kan underlätta problemet, även om det inte är en universallösning. READ MORE

  4. 3. Germination dynamics of soybean cultivars in relation to common spring germinating weeds

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Sofie Pålsson Andersson; [2021]
    Keywords : soybean; cardinal temperatures; base temperature; cold tolerance; germination; Nemoral climatic zone; weeds;

    Abstract : Soybeans are one the most traded crops in the world with main production areas in north and south America. Europe only produces 5 % of its domestic need for soybean. In the Nemoral zone of northern Europe no commercial cultivation of soybeans exists today. READ MORE

  5. 4. Can ambient temperature patterns predict fireweed phenology?

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Jennifer Chaimungkhun Johansson; [2021]
    Keywords : fireweed; Chamaenerion angustifolium; growing degree-days; camera trap; phenology;

    Abstract : The Earth’s climate has been changing with greater intensity and frequency in recent years. These changes, especially the warmer climate, have advanced plant phenology, thus increasing the risk of interspecific temporal mismatches, for example pollinators and pollinated flower species.

  6. 5. Impact of environmental variables on tundra vegetation onset of flowering explained by survival modelling

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Hanna Jonsson; [2019]
    Keywords : Flowering; Phenology; Cox proportional hazard model; Tundra; International tundra experiment; Climate change; Physical Geography and Ecosystem analysis; Earth and Environmental Sciences;

    Abstract : Timing of phenological events are highly related to climate and is one of the first signs of ecosystem responses to the climate change. Timing of flowering phenology is an important trait influencing the distribution and fitness of plants species. READ MORE
