Mycorrhizal promotion of host stomatal conductance in relation to irradiance and temperature

Abstract: Colonization of roots and soil by arbuscular mycorrhizal (AM) fungi sometimes promotes stomatal conductance (gs) of the host plant, but scientists have had difficulty predicting or manipulating the response. Our objective was to test whether the magnitude of AM influence on gs is related to environmental conditions: irradiance, air temperature or leaf temperature. Stomatal conductances of two groups of uncolonized sorghum plants were compared to gs of plants colonized by Glomus intraradices (Gi) or Gigaspora m… Show more

“…A high mycorrhizal root tip abundance may promote several plant responses, including higher stomatal conductance (Augé et al 2004 ), improved plant-water relations (Muhsin and Zwiazek 2002 ; Shi et al 2002 ; Kennedy and Peay 2007 ), more effective nutrient acquisition (Wallander et al 1994 ; Wallander and Hagerberg 2004 ), greater resistance to fungal pathogens (Branzanti et al 1999 ), and higher photosynthetic activity (Dosskey et al 1990 ). Growing in a well-mixed fungal community (pot substrate containing a forest soil mix), seedlings were subjected to both beneficial and less beneficial EMF species in terms of carbon costs to the hosts (Bever et al 2009 ).…”
