In addition, global climate change is expected to regionally increase the number of floods within decades, urging for more flood-tolerant crop cultivars to be released. The aim of this thesis was to assess mechanisms conferring rice (<em>Oryza sativa<\/em>) and wheat (<em>Triticum aestivum<\/em>) flood tolerance, focusing on the role of leaf gas films during plant submergence. Reviewing the literature showed that wheat germplasm holds genetic variation towards waterlogging (soil flooding), and highlighted traits such as improved internal aeration of the root system and short term anoxia tolerance of seminal roots as conferring tolerance. However, further work on especially anoxia tolerance and genotype \u00d7 environment interactions is required in order to explore the available genetic resources. Experimental work assessed the physiologic, metabolomic and genetic response of wheat subjected to complete submergence, documenting contrasting submergence tolerance between two cultivars. Manipulating leaf gas film presence affected wheat and rice submergence tolerance such as plant growth and survival. However, leaf gas film retention times did not differ between 14 winter wheat cultivars. Due to the low genetic variation in wheat gas film retention times, a future prominent role of leaf gas films in improving wheat submergence tolerance was not generally supported.<\/p>\n<p><em>The thesis is available for inspection at the Freshwater Biology Section, Universitetsparken 4, 3rd floor.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Max Herzog defends his thesis Mechanisms of flood tolerance in wheat and rice &#8211; The role of leaf gas films during plant submergence.
