Sunflower seedlings of 4 varieties grew better on inoculation with Glomus fasciculatum at 10% soil-water regime as against lesser
growth in uninoculated series of seedlings. There was no difference in percent germination of seeds between inoculated and
uninculated series. Mycorrhizal infection in sunflower roots was visible under microscope in 15 days old roots of sunflower seedlings.
The growth of sunflower seedlings was better at 10% soil water regime than at 5% soil-water regime. The better growth of mycorrhiza
infected sunflower seedlings is related to the entry of extramatrical mycorrhizal hyphae of the soil into the intramatrical region of roots
than without inoculation at different soil moisture content. The VAM inoculated sunflower seedlings produced arbuscules in the
cortical cells of roots whereas in uninoculated series of pots mycorrhizal hyphae and arbuscules was not seen in roots of sunflower
seedlings. The VAM-inoculated sunflower seedlings showed better growth because of mycorrhization and thus could meet up water
stress more efficiently than non-mycorrhiza sunflower seedlings at different soil-water regimes.
