ANATOMICAL EFFECTS OP INDOLEBUTYRIC ACID ON PEDICEL ABSCISSION OF CORCHORUS
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.
