| Abstract:
Changes in photosynthetic relations associated with infection by Phytophthora cinnamomi were studied in inoculated plants of Castanea sativa (cv. Judia), many hybrid clones (C. crenata × C. sativa) and the ink disease resistant COLUTAD. The aim of this work is to analyse the effect of the inoculation of the ink disease soil pathogen Phytophtora cinnamomi on photosynthesis. Results indicate an increase (11 to 35%) in the photosynthetic rate in hybrid plants (Castanea sativa × Castanea crenata) in contrast to the C. sativa plants (decrease of 19%). | |
