Abstract

The compound N-(l,l-dimethylpropynyl)-3,5-dichlorobenzamide affected the development of quackgrass (Agropyron repens (L.) Beauv.) by inhibiting the growth of meristematic regions. The nodes at the apex of treated rhizomes became swollen and necrotic and exhibited increases in DNA, RNA, and protein over untreated rhizomes. These changes in the terminal nodes were accompanied by a dramatic increase in the levels of cellulase and by several disruptive changes in the meristematic, nodal, and internodal tissue of quackgrass rhizomes.
