Effect of diuron and metribuzin on the root tip mitosis of water hyacinth (Eichhornia crassipes)

, : Effect of diuron and metribuzin on the root tip mitosis of water hyacinth (Eichhornia crassipes). Proceedings of the 8th international symposium on aquatic weeds, Uppsala, Sweden, 13-17 August 1990: 11-15

Laboratory experiments revealed that a gradual decrease in the percentage of mitotically active root tip cells of E. crassipes occurred as the concn (1-80 ppm) and contact time (24-72 h) of diuron and metribuzin increased. Complete inhibition of mitosis was observed with 40 ppm of metribuzin and diuron after 24 and 48 h, resp. Abnormalities of chromatin and chromosomes were rarely observed.
