Abstract EN
The use of enzyme could facilitate pathogen penetration into plant host.
Here the combination of cellulase and pectinase was ascertained on the pathogenicity of F.
compactum (1.4×106 propagules ml−1) on broomrape tubercles.
F.
compactum alone infected all the inoculated tubercles but did not kill any significant number.
Infested tomato roots that were inoculated with mycelia plus pectinase (20 U ml−1) had over 50% tubercles dead one week after treatment.
Those inoculated with mycelia plus cellulase (20 U ml−1) had above 60% mortality.
Mixtures of mycelial plus the two enzymes (10 U ml−1 of each enzyme) showed synergy.
The activity catalyzed by an enzyme is a measure of the amount of enzyme present.
It was shown that, in a 1 mg (10 U mg−1) cellulase used, 0.055 mg pectinase (1.1 U mg−1) is present.
This explains why mycelial plus cellulase mix contends with mycelial plus the two enzymes.
