Abstract: Since water hyacinth (Eichhornia crassipes) causes many problems in the irrigation and drainage canals in Egypt. Weekly records were recorded on the effect of temperature on the germination and growth of this floating weed at an irrigation canal in the Agricultural Experiment Station at Bahteem, Kalubia Governorat.
The (percentage of germinating buds, leaf number, leaf length, fresh and dry weight) and plant growth were recorded (number of plants, leaf number, leaf length, fresh and dry weight, off-sets and inflorescence)during the period of 1993 and 1994.
The results showed that the vegetative organs began to germinate on 14-2-1994 in submerged water. No seed germination was observed during this study area. The submerged plants floated on water surface after 4 weeks from germination from 14-3-1994 till mid-June yearly. The floated plants produced off-sets after 3 weeks from floating during April. Plant growth increased by increasing time and temperature till 26-7-1994 then decreased.
From the respective results, it could be recommended to control water hyacinth yearly easily during June to obtaining successful control with less costs for the suitable temperature. Since all active germinating plants on the water surface.
