ANATOMICAL EFFECTS OP INDOLEBUTYRIC ACID ON PEDICEL ABSCISSION OF
CORCHORUS A. S. Islam and Nasim Bhutto
Abstract:
Abscission of pedicel of Corchorus trilocularis after its pollination
with C. olitorius is completely suppressed by the application of IB A
(300 PPM) around the pedicel of the pollinated flower. Longisections of
the pedicels oj self-pollinated flowers, when compared with those of the
treated ones showed no difference in the shape and size of their cells
in the abscission zone.
In the crosses without IBA abscission zone was found to be
differentiated 42 hrs after pollination by the concurrent occurrence of
cell division and initiation of lysis. Department of Botany, University of Sind, Jamshoro. |
