Figure 7 (a) Mean curves of germination rate versus time for
untreated spores; (b) mean curves of germination rate versus time for
spores after different times of sodium hypochlorite treatment; (c) mean
curves of growth length versus time for spores after sodium hypochlorite
treatment; (d)–(h) curves of cell length versus time for single spores
treated with sodium hypochlorite for 0–20 min.
In addition, we found that surviving spores after sodium hypochlorite
treatment were able to germinate and grow to form trophoblasts; however,
inactivated spores were unable to germinate despite incubation for up to
3 h (Figure 6 ). Notably, there were differences in the curves
of cell length versus time for eight single spores (treated and
untreated groups) (Figure 7 (d)–(h) ), indicating that there
were individual differences in the effect of sodium hypochlorite on
spores under the same conditions, reflecting the individual
heterogeneity of the spores [31].
