Activity of Pectin Esterase and Cellulase in the Abscission Zone of Citrus Leaf Explants

Abstract

The activity of pectin esterase and cellulase in abscission of citrus explants was studied. No relation was established between pectin esterase and abscission, while cellulase activity was markedly increased before abscission and for a certain period after excision. IAA and cycloheximide delay abscission and cellulase activity, while ethylene and, to a lesser extent, GA3 accelerate them. Application of cycloheximide during the lag period and before cellulase activity can be measured, inhibits to a certain extent the formation of cellulase. An escape from the inhibitory effect of cycloheximide is detected when inhibitor is supplied at the end of the lag period.
