Abstract EN

The aim of this experiment was to study the effect of gamma rays ( 0, 10, 20, 30, 40 and 50 Gy) and time intervals (2and 4weeks) on number and weight of shoots of Grandnaine banana variety propagated in vitro.

The result showed that the high doses (20, 30, 40,50 Gy) of gamma ray had significant negative effect on number and weight of shoots while 10 Gy dose showed that the highest number and weight of shoots compared with the control.

Moreover significant difference were found in the number and weight of shoots after 4 weeks compared with 2 weeks.

The interaction between radiation and time interval showed that the doses 0, 10 and 20 Gy led to a significant increase in number and weight of shoots in 4 weeks compared with 2 weeks, however there were no significant effect between time intervals and the high doses 30, 40,and 50 Gy.
