All variables evaluated of in vitro plantlets derived from
irradiated tubers, showed statistically significant differences
(percentage of explants with shoots p= 0.00001, percentage
of contaminated explants p= 0.0001 and shoot height p=
0.0001), so it can be stated that different radiation doses used
influenced the budding and seedlings growth. The shoot
development began on the third day after in vitro seeding
and ended on the seventh day. Plants treated with gamma
radiation of 5 Gy showed a shoots’ growth equal than the
control’s treatment (100%) and this variable decreased when
radiation doses increased (Table 1).
