An experiment was conducted to
assess the effect of three Glomus species on the percent success and survival
of jamun grafts in relation to the chlamydospores and root colonization
behavior. A factorial completely randomized design experiment was conducted by
the soil inoculation of three Glomus species fungi namely Glomus fasciculatum, Glomus
leptotichum and Glomus intraradices to jamun seeds (cultivated and wild) sown
in polybags at five grams per polybag. The chlamydospores count and percent
colonization at two stages i.e. one month after sowing and grafting stage was
done from the soil and expressed in numbers per 50 grams and percentage
respectively. Cultivated jamun rootstocks inoculated with Glomus fasciculatum
exhibited significantly maximum spore population in the rhizosphere of one
month old rootstocks (242.00) and at grafting stage (519.00), while
significantly minimum spore population was recorded in uninoculated rootstocks
at one month after sowing (23.33) and at grafting stage (91.00). Wild jamun
rootstocks inoculated with Glomus fasciculatum recorded significantly maximum
spore population in the rhizosphere of one month after sowing (175.66) and at
grafting stage (421.33). Higher root colonization was observed in my corrhiza
inoculated seedlings compared to uninoculated seedlings. Wild jamun rootstocks
inoculated with Glomus fasciculatum recorded significantly higher root colonization
at one month after sowing (80.00%) and at grafting stage (82.00%) which was on
par with rootstock inoculated with Glomus leptotichum at one month after sowing
(78.20%) and at grafting stage (80.00%). Zero root colonization was recorded in
uninoculated seeds one month after sowing (0.00%) and at grafting stages (5.50%)
