摘要:

The aquatic weed hydrilla (Hydrilla verticillataRoyle) was discovered growing in the Potomac River, south of Alexandria, VA, in Kenilworth Aquatic Gardens, Washington, D.C., and in the Chesapeake and Ohio (C&O) Canal near Seneca, MD. Cultures in Florida of the Kenilworth clone produced male flowers. This is the first report of the occurrence of the male in the U.S. Two distinct isoenzyme patterns have been identified for plants from various locations in the U.S., corresponding to a monoecious strain and a dioecious female. The occurrence of the wild colonies of the monoeciousHydrillagreatly increase the potential for physiological diversity through sexual reproduction, which may have serious consequences for the management of this weed.
