Abstract
This study reports the effect of increased CO2 and temperature on powdery mildew (Erysiphe necatrix) of grapevine evaluated under controlled conditions. Grapevine potted plants, belonging to the cv Moscato and Barbera, were grown in phytotrons under four different simulated climatic conditions: standard CO2 concentration for the area (450 ppm) with standard (ranging from 22 to 26°C) and elevated temperature (4°C higher than standard), elevated CO2 (800 ppm) with standard and elevated temperature. Physiological responses of grapevine and pathogen development were studied. Results showed an increase of the chlorophyll content with higher temperatures and CO2 concentration, to which consequently corresponded an higher fluorescence index. Disease incidence did not significantly vary between cultivars. In conclusion, an increase in CO2 did not affect powdery mildew incidence, probably due to the increased photosynthetic activity of plants under such conditions.
Zusammenfassung
Diese Untersuchung beschreibt den Einfluss von erhöhter Temperatur und erhöhtem CO2-Gehalt auf den Echten Mehltau der Weinrebe (Erysiphe necatrix) unter kontrollierten Bedingungen. Getopfte Weinreben der Sorten Moscato und Barbera wurden in Klimaschränken unter vier verschiedenen Simulationsbedingungen angezogen: die regionale Standard- CO2-Konzentration (450 ppm) mit entweder (1.) Standard- Temperatur zwischen 22 to 26°C oder (2.) um 4°C erhöhter Temperatur, oder erhöhter CO2-Konzentration (800 ppm) mit (3.) Standard- oder (4.) erhöhter Temperatur. Unter diesen Bedingungen wurden physiologische Reaktionen des Weins und die Entwicklung des Pathogens untersucht. Dr Chlorophyllgehalt der Weinblätter stieg mit zunehmender Temperatur und CO2-Konzentration, was mit einem höheren Fluoreszenzindex einherging. Die Befallsstärke zeigte keine signifikanten Sortenunterschiede. Aus den Ergebnissen kann gefolgert werden, dass erhöhte CO2-Gehalte die Befallsstärke des Echten Mehltaus der Weinrebe nicht erhöhen, was möglicherweise auf die erhöhte Photosyntheseaktivität der Pflanzen unter diesen Bedingungen zurückzuführen ist.
