Descriptif
The main purpose of this thesis is to better understand of how different timing of inoculation, water supply levels, and environmental factors, such as site geography, soil properties, and precipitation, influence the efficiency of arbuscular mycorrhizal inoculation in a crop production system. We used processing tomato UNO ROSSO F1, considering its economic importance to answer the following questions : - Which inoculation is more effective in alleviating water stress impact on plants, pre transplant inoculation at sowing or field-inoculation at transplant ? - To what degree of the prevailing drought stress do AMF alleviate water stress impact on plants ? - What is the mechanism in which the AM symbiosis back up host plants to overcome water stress ; is it drought stress avoidance or drought stress tolerance ? - Do AMF reserve and/or increase plant production under different soil moisture conditions ? - What is the role of AMF in preserving and enhancing fruit quality under different soil moisture conditions ? - What are AMF inoculation effects on the performance of certain physiological and biochemical processes of host plants under different soil moisture conditions ? - Could AMF be used as a mitigation practice tool in facing water scarcity from the agricultural and ecological point of view ?
