Abstract
Infection of sugarcane and maize plants with SCMV strain D and its substrains Da and De caused a makred decrease inleaf chlorophylls (A) and (B) while other pig-ments (xanthophyll and carotine) wer not markedley affected. SCMV isolates DcI (highly pathogenic), DVIII (moderately pathogenic) and DI (weakly pathogenic) caused a significant reduction in reducing, non-reducing and total sugars of infected sugarcane leaves. Infection of different sugarcane varieties with Dc I, D VIII and DI virus isolates increased invertase activity in stalks. The highly pathogenic isolate DcI induced highest enzyme activity folloed by moderately pathogenic isolate D VIII and finally weakly pathogenic isolate D I.
Zusammenfassung
Die Infektion von Zuckerrohr- und Maispflanzen mit dem Zuckerrohr-mosaikvirus (SCMV), Stamm D und seinen Substämmen Da und Dc, verusachte eine erhebliche Verminderung des Chlorophyll A und B in den Blättern, während Carotin und Xanthophyll kaum beeinträchitgt (mittel-pathogen) und D I (schwach pathogen) verursachten eine signifikante Verminderung der reduzierenden, nicht reduzierenden und Gesamt-Zucker in den Blättern. Die Infektion verschiedener Zuckerrohrsorten mit den Virus-Isolaten führte zum Ansteigen der Inverstase-Aktivität in den Stengeln.
