The highest increase in shoot length was achieved in
elongation media containing 0.2 mg L-1 GA3 and 0.5 mg L-1
BA with an average growth of 48%. However some leaf ab-
scission were observed on the shoots produced in this me-
dia. When both elongation rate and shoot vigor and health
were taken into account, the media supplemented with 0.1
mg L-1 GA3 and 0.5 mg L-1 BA resulted both a high elonga-
tion are (42%) and healthy dark green shot leaves (Table 2).
Kotsias and Roussos (2001) reported that a combination of
0.5 mg L-1 GA3 with 2 mg L-1 BA and 3 mg L-1 AgNO3, en-
hanced elongation of lemon adventitious shoots. On the
other hand, BA concentrations over 2 mg L-1
repressed elon-
gation of the regenerated shoots.
