Turions production is the dominant means of propagation in Potamogeton crispus L. To understand how parental population and their living environmental factors influence the turions production of P. crispus L., a field research was conducted in Nansi Lake in Yellow River Flood Plain and southwestern Shandong Province, China. This study showed that P. crispus biomass and asexual turions showed an almost uniform spatial distribution pattern. Water depth, attenuation coefficient of light, sediment water content, sediment organic matter content, and pH were significantly related to P. crispus biomass, turions weight, and turions number. Single turion weight was determined only by P. crispus biomass, while turions number was simultaneously determined by P. crispus biomass and sediment water content. Turions weight mainly depended on turions number rather than single turion weight, and maternal biomass and sediment water content determined turions weight by affected turions number rather than single turion weight.
