  1. 1. Winter wheat exudates : Improving wheats resilience to drought

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Freja Haverland; [2024]
    Nyckelord :drought; PGPR; exudates; agriculture; food security;

    Sammanfattning : Wheat (Triticum aestivum) is a crop that dominates the diets of about 35% of the world's human population. But wheat yields can be severely affected by drought. Therefore, in this experiment, root exudation of winter wheat was compared to find out how exudation changes during drought stress. LÄS MER

  3. 2. Modelling the growth of Pinus sylvestris L. monocultures in Sweden depending on the absorbed light

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Mateusz Grzeszkiewicz; [2022]
    Nyckelord :climate change; forest modelling; light use efficiency; photosynthetically active radiation; Scots pine;

    Sammanfattning : Stand growth models are an important aid in contemporary sustainable forest management as a major planning and decision-making tool. However, climate change influencing growth conditions worldwide is a challenge to commonly used empirical models as they do not provide enough flexibility, which can result in inaccurate predictions and thus wrong decisions and sub-optimal results.

  4. 3. Non-Destructive Biomass and Relative Growth Rate Estimation in Aeroponic Agriculture using Machine Learning

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Oskar Åström; [2022]
    Nyckelord :Machine Learning; Image Analysis; Aeroponics; Hydroculture; Relative Growth Rate; Multi-variate Regression; Neural Network; ResNet; Plant Growth; Plant Physiology; Technology and Engineering;

    Sammanfattning : Optimising plant growth in a controlled climate requires good measurements of both biomass (measured in grams) and relative growth rate (measured in grams of growth per day and gram of plant). In order to do this efficiently and continuously on an individual level during plant development, this has to be done non-destructively and without frequent and labor intensive weighing of plant biomass.

  5. 4. Closer-to-nature forestry : Mapping the views of some stakeholders to the new EU Forest Strategy

    Kandidat-uppsats, SLU/Dept. of Forest Genetics and Plant Physiology

    Författare :Astrid Bygge; [2022]
    Nyckelord :Closer-to-nature silviculture; Forest management methods; Stakeholder preferences; Policy instruments; Forest governance;

    Sammanfattning : The European Commission adopted the European (EU) Forest Strategy in 2021, where forests and forest management practises such as closer-to-nature forestry (CNF) are identified as a key in solving the two crises of climate change and biodiversity loss. This interview study analyses the attitudes of different forest stakeholders towards CNF and their preferred regulation method of it. LÄS MER

  7. 5. Capillary Organic Electronic Ion Pump for Delivering Malic Acid - Towards Better Understanding of Drought Tolerance in Tropical Plants

    Master-uppsats, Linköpings universitet/Laboratoriet för organisk elektronik; Linköpings universitet/Tekniska fakulteten

    Författare :Alexandra Sandéhn; [2021]
    Nyckelord :malic acid; malate; ion delivery; implantable devices; organic bioelectronics; plants; Teknisk fysik; Teknisk fysik;

    Sammanfattning : Delivery of biologically relevant ions such as drugs, neurotransmitters and hormones have been recognized as powerful a tool to control physiology of animals and plants for research purposes and practical applications. In the plant research community, ions are most commonly delivered as part of a solvent by soaking, spraying, pipetting or by adding to the soil. LÄS MER
