The symbiotic performance of three isolates (CMG854,
CMG857 and CMG 860) with the mung beans shoot and
root was evaluated in greenhouse experiments. At shoot
length of plants inoculated with strain 860 ranked the
highest and it was greater than that of the un inoculated
plants the root elongation of germinating seeds of Vigna
radiata was highest with isolate CMG860, followed by
CMG857 and CMG854 compared to the control,
CMG860 showed significant root and shoot elongation.
(Shahab and Ahmed, unpublished data) Almost all lateral
roots were densely covered by root hairs whereas very
few or none developed on un inoculated control plants
