A biochemical study of tobacco subjected to"Cotyledon test"conditions : effect of magnesium, reactions of plants resistant and susceptible to Peronospora tabacina. III. Chemiluminescence induced in tobaccos contaminated or not by blue mold

MOLLE E.; EDREVA A.; BATSCHEV S.
In young tobacco plants at the cotyledon stage, induced chemiluminescence (CHL), which is an indicator of the bio-physical condition of the membranes, depends on nutrition, the age of the plant and the degree of contamination by Peronospora tabacina A. If the resistance genes are expressed (Mg2+) the CHL is hardly modified. On the other hand, it greatly decreases in a repressive medium (Knop 1/2). This method provides a new approach to host-parasite interactions.
