Mycorrhizal fungi species Glomus fasciculatum was used
to determine its effects on tomato growth, yield, fruit
properties, nutrient uptake and substrate ion accumulation
of plants grown hydroponically under open and re-cycling
(closed) perlite substrate. AM inoculation in both open and
closed soilless systems did not increasingly influence the
vegetative plant growing and nutrient uptake of tomato
cultivar M19. However, fruit yield absolutely increased with
inoculation. AM inoculated tomato plants could effectively
use photo assimilates for fruit production instead of
vegetative growing. In the closed system with AM, ion
accumulation and EC increases (salinity effects) were well
controlled. Results indicated that mycorrhizal inoculation
improved yield and fruit size, which can help alleviate
deleterious effects of re-cycling soilless systems for
tomato crop.
