The epidemiology of tomato brown root rot

F. T. LAST; MARION H. EBBEN Annals of Applied Biology 1966. doi:10.1111/j.1744-7348.1966.tb06870.x

Other claims from this paper (19)

Observation Three brown root rot symptoms occurred on tomato roots in infested soil without nematodes.
Observation Brown lesions appeared within a week of planting in heavily infested soils.
Observation Corkiness and black dot rarely appeared until the third month after planting.
Observation Black dot incidence sometimes rose sharply toward season end.
Association Observations suggested GSF caused more damage than C. atramentarium.
Association Yield was unrelated to black dot incidence.
Association Yield was inversely proportional to brown lesion occurrence.
Association Yield was inversely proportional to corkiness occurrence.
Association The yield relation with brown lesions was significant within eight weeks of planting.
Observation Early brown lesions mostly yielded GSF cultures, whereas later lesions more often yielded C. atramentarium.
Intervention effect Most GSF cultures produced 10 mm brown lesions on tomato seedling roots within two weeks.
Intervention effect C. atramentarium inoculation produced small pink lesions.
Intervention effect Pyrenochaeta inoculation produced no lesions.
Intervention effect GSF caused greater root damage, including root loss, in soil tests.
Association GSF root damage was reflected in decreased aerial growth.
Association GSF root damage was reflected in smaller fruit yields.
Intervention effect C. atramentarium did not affect aerial growth or fruit yield in soil tests.
Intervention effect In the second year, GSF lowered six week picking yield from 1.96 kg in controls to 1.02 kg per plant.
Observation GSF damage shifted with plant age: brown lesions appeared within days, while corkiness appeared after two to three months with stem lesions and yellow leaves.

Intervention effect Independently of the light regime, early growth of all organs was slower in MDHAR-silenced cherry tomato lines.
Intervention effect MDHAR silencing decreased final fruit yield.
Intervention effect Photosynthesis was altered in MDHAR-modified lines.
Intervention effect Accumulation of hexoses and sucrose was altered in a light-dependent manner in plantlets.
Intervention effect Sucrose accumulation was repressed in young fruits of MDHAR-silenced lines.
Intervention effect The phenotype of MDHAR-silenced lines was partially restored by reducing fruit load.
Association MDHAR activity is correlated with sugar levels under high light in cherry tomato.
Mechanism Ascorbate and MDHA appear to be involved in control of growth and sugar metabolism in cherry tomato.
Recommendation The associated enzymes could be potential targets for yield improvement.
