Aquatic Plant Control Research Program: Pilot Study: Carbohydrate Allocation in Hydrilla Biotypes

Abstract

Carbohydrate allocation in monoecious and dioecious hydrilla (Hydrilla verticillata (L.f) Royle) was examined under various water temperature and photoperiod regimes. Propagule production of monoecious hydrilla was also evaluated under different shoot-cutting treatments. Both hydrilla biotypes accumulated starch (35 percent) in shoots under short photoperiods, but only monoecious plants were able to form tubers and turions. High temperature (35 C) promoted fragmentation in both biotypes after 8 weeks of growth. Cutting to 1-cm height decreased shoot starch content and inhibited tuber production in monoecious hydrilla. Shoot removal as a possible means of decreasing propagule formulation in monoecious hydrilla is suggested.
