Aloe vera soft rot disease, which also induced activity of Pectate lyase activity, Pectin methyl esterase, Polygalacturonase, pectin trans eliminase activity. The enzyme activity of inoculated aloe plants increased from the two day till the six DAI and slowly declined thereafter in all the 15 isolates.

Abstract


Aloe vera soft rot disease, which also induced activity of Pectate lyase activity, Pectin methyl esterase, Polygalacturonase, pectin trans eliminase activity. The enzyme activity of inoculated aloe plants increased from the two day till the six DAI and slowly declined thereafter in all the 15 isolates.
