of A. fl avus increased more rapidly compared to T. viride .
Also, the radiosensitivity of A. fl avus was notably less than
T. viride . Reduction in colony diameter was observed in
all of these fungi after radiation. However, contrary to
A. alternata and C. geniculata , both A. fl avus and T. viride
manifested signifi cant ( P 0.05) delay in colony growth
compared with their respective control group, with no
signifi cant ( P 0.05) delay in spore germination at higher
absorbed doses after three days (72 h) (2 – 3 kGy) (Table I).
Germ tube length of all the selected fungi ( P 0.05)
decreased when exposed to gamma rays. However, the rate
of change of length was diff erent ( P 0.05) for diff erent
fungal species (Table II). Th e percentage mean decrease in
germ tube length of C. geniculata and T. viride was higher
( P 0.05) as compared to A. alternata , and A. fl avus . Also,
T. viride showed maximum radiosensitivity with respect to
changes in germ tube length. In case of C. geniculata , at a
dose of 2 kGy the germ tube length ( P 0.05) decreased by
73% whereas A. alternata showed multiple germ tube formation
at the same dose (Figure 2b). A. fl avus manifested
( P 0.05) the least radiosensitivity in connection with germ
tube morphology and formed multiple germ tubes at an
absorbed dose of 2.5 kGy (Figure 2d). Germ tube diameter
of unexposed T. viride was ( P 0.05) much greater than
that of non-irradiated A. alternata , A. fl avus or C. geniculata.
Th e germ tube diameter of all the fungal species also
decreased in a dose-responsive manner but the intensity
of this decrease was much higher in case of T. viride
(Table III). It was observed that the fungi which showed the
least radiosensitivity ( P 0.05), A. alternata and A. fl avus ,
exhibited increased germ tube formation compared to the
control (Figures 2a, 2c). Th e results show that germ tube
diameters increased (malformation) during the formation
of multiple germ tubes (Table III).
