Effects of three fungal pathogens on water relations, chlorophyll fluorescence and growth of Quercus suber L

Abstract: -Some physiological and growth parameters were studied in cork oak plants inoculated with three pathogenic fungi (Botryosphaeria stevensii, Hypoxylon mediterraneum and Phytophthora cinnamomi) in order to understand the effects of the fungal infection. All inoculated fungi induced the reduction of daily stem growth, stomatal conductance, air-leaf temperature and photochemical efficiency. The more aggressive pathogens, B. stevensii and P. cinnamomi, induced the sharpest decline in all growth and physiological pa… Show more

“…Both fungal infections provoke bark and vascular cambium alterations that may affect water relations (e.g. reduction of flux to the leaves) as observed in cork oak plants inoculated with vascular pathogens such as Botryosphaeria stevensii or Hypoxylon mediterraneum [24]. In our work, the decrease in stomatal conductance in infected plants might be indicative of water stress and consequent photosynthetic reduction.…”

“…En el caso del parámetro F v /F m se constató una disminución de la eficiencia del FSII y fotoinhibición de la fotosíntesis, reflejadas en una disminución de este parámetro a partir de las 120 hpi. El efecto negativo sobre la fotosintesis es semejante a lo verificado como consecuencia de infecciones causadas por patógenos foliares como Puccinia psidii G. Winter (Alonso et al 2011, Sebela et al 2012) y de raíz, como Phytophthora cinnamomi Rands (Luque et al 1999) y Fusarium oxysporum Schltdl. (Wagner et al 2006).…”

“…En cuanto al metabolismo primario, el ataque de patógenos resulta en una disminución de la tasa fotosintética (Kocal et al 2008, Luque et al 1999, Wagner et al 2006, Alonso et al 2011, la que puede estimarse mediante la fluorescencia de la clorofila a y los parámetros a través de los cuales se mide (F 0 y F v /F m ) (Maxwell & Johnson 2000).…”
