Conclusions
The present study was the first attempt to
investigate the reaction of two native Greek
tomato varieties, ‘Chondrokatsari Messini-
as’ and ‘Katsari Santorinis’, to infection by
F. oxysporum
f. sp.
lycopersici
and
R. solani
.
Results showed that both tomato variet-
ies were susceptible to
F. oxysporum
f. sp.
lycopersici
and
R. solani
infection. Howev-
er, ‘Chondrokatsari Messinias’ was found to
be less susceptible to
F. oxysporum
f. sp.
ly-
copersici
compared to ‘Katsari Santorinis’.
Both of the pathogens negatively affected
biomass production of var. ‘Chondrokatsari
Messinias’ but not that of ‘Katsari Santorinis’.
The number of flowers produced by ‘Chon-
drokatsari Messinias’ was negatively affect-
ed by
R. solani
but not by
F. oxysporum
f. sp.
lycopersici.
Infection of both tomato variet-
ies by
R. solani
also caused reduction in the
CO
2
assimilation, stomatal conductance and
transpiration.
Additional work is required on the inter-
action between the two native Greek toma-
to vars ‘Chondrokatsari Messinias’ and ‘Kat-
sari Santorinis’ and the soil-borne fungi
F.
oxysporum
f. sp.
lycopersici
and
R. solani
as
well as on the management of the diseases
caused by these pathogens.
The Benaki Phytopathological Institute is
gratefully acknowledged for providing the
strains of Fusariumoxysporumf. sp. lycopersici
(BPIC2550) and Rhizoctonia solani (BPIC2531)
used in the present study.
