  1. 1. New methods for seed potato production: an investigation into the production and farmer uptake of mini tubers in South Africa

    University essay from SLU/Department of Biosystems and Technology (from 130101)

    Author : Alba Sáez Fernández; [2018]
    Keywords : mini-tubers; Chlorophyll fluorescence; Leaf Area Index; small-scale farming;

    Abstract : Potatoes are by far the most produced fresh vegetable crop in South Africa. Remarkably, potato sales represent more than 30% of the turnover in the Fresh Produce Markets (FPM). READ MORE

  2. 2. Effects of the carotenoid inhibiting herbicide diflufenican on the photosynthesis of benthic algae

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Jelena Rakovic; [2014]
    Keywords : benthic algae; freshwater; herbicides; diflufenican; PAM; fluorescence; Lake Erken; photosynthetic efficiency;

    Abstract : Throughout the world, the large-scale use of pesticides in agriculture is an area of concern due to known harmful effects on human and environmental health. Mixtures of different pesticides are found in lakes and streams, where their presence endangers aquatic organisms, like benthic algae, and the ecosystem services they provide. READ MORE

  3. 3. Effekt av torkstress på tillväxt hos annuella ogräs

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Mattias Persson; [2013]
    Keywords : Torkstress; Tillväxt;

    Abstract : En minskad herbicidanvändning är önskvärt ur flera aspekter. Bäst effekt på plantan ska fås från appliceringen om denna är i aktiv tillväxt. För att herbicider ska kunna användas framgångsrikt så är en avstannad tillväxt en förutsättning för en lyckad bekämpning. READ MORE

  4. 4. Analysis of salt tolerance in three widely used accessions of Arabidopsis thaliana: a photosynthetic approach

    University essay from Linköpings universitet/Molekylär genetik

    Author : Pavan Tangirala; [2011]
    Keywords : Salt tolerance; photosynthetic activity; chlorophyll fluorescence; Arabidopsis ecotypes;

    Abstract : Salt stress is one of the major problems in the present world’s agriculture. Plants encounter drought stress even in the availability of water because of osmotic imbalance in the cell due to excess salts. Plants avoid water uptake, which in turn decreases the photosynthetic activity. READ MORE

  5. 5. Does arbuscular mycorrhiza symbiosis increase the capacity or the efficiency of the photosynthetic apparatus in the model legume Medicago truncatula?

    University essay from Linköpings universitet/Molekylär genetik

    Author : Ateeq ur Rehman; [2010]
    Keywords : Medicago truncatula; Arbuscular mycorrhiza symbiosis; Photosynthesis; Chlorophyll fluorescence; Oxygen evolution; Lhcb1 and Lhcb2 proteins content; phosphor uptake; Reproductive fitness;

    Abstract : The Arbuscular mycorrhiza (AM) is an endosymbiont of higher plant roots. Most land plants and cultivated crops are concerned to AM symbiosis. This endosymbiosis is based on the mutual exchange of nutrients between plant and fungus. Therefore, AM symbiosis leads to an increased demand for photosynthetic products. READ MORE
