Effect of Several Herbicides on Proteolytic Activity of Squash Seedlings

Abstract

The proteolytic activity of the cotyledons of squash ( Cucurbita maxima Duchesne) increases several fold during germination. The different herbicides varied widely in their ability to inhibit this increase. An attempt was made to correlate this inhibition with inhibition of growth. A direct correlation was evident only when the inhibition of proteolytic activity was severe or very slight to nonexistent.
