RESUMO
The possible role of pectin esterase in abscission of bean and coleus leaves was re-examined using improved methods for its extraction. Its possible role in abscission of flowers of tobacco and leaves of soybean. cotton, mulberry, magnolia, and euonymus was also examined. In seven of the eight species, no detectable changes in abscission zone pectin esterase activities immediately preceded abscission. Therefore, pectin esterase probably plays no causal role in abscission in these species.
