Abstract
Three different age
group of P. Deltoides stem cuttings, viz. 6 months (young age), 12 months (middle age), and
24 months (old age), have been selected
to develop their regeneration potential with lenticel development on the stem
cuttings, which were treated with various continuous and fractionated doses of
gamma rays. Young age radiated cuttings were also presoaked with Kinetin 500 ppm for their
synergistic effects. The treated cuttings were applied in rainy season. The number and area in
all treated cuttings were more favorable at lower continuous and fractionated doses. Maximum
lenticel induction number percentage (80%) have been observed under 2KR-F treatment in old age stem
cuttings, which is higher than in middle and young age treated cuttings in all applied continuous and fractionated
doses. Lower concentration 500R-C (52% in old age), 2KR-F (58% in young age) and 2KR-F with Kinetin
500ppm (49% in young age) showed better induction
percentage in comparison of control. The area of lenticels was also found to be
higher in the cuttings treated with low concentration of gamma rays, i.e.,
2KR-C 69% at middle age, 2KR-F 57% at old age and 2KR-C 52% at young age which
was higher than the control old age cuttings (22%).
