Abstract

A 4-year study was made at Huntley, Montana. When the seed coats were ruptured, 100% germination of sago pondweed (Potomogeton pectinatus L.) seeds occurred. Tubers grow in soil to a depth of 18 inches. Formation of tubers was greatest in August. Single plants of sago pondweed, grown from a tuber and a seed, in 6 months developed over 36,000 tubers and 63,000 seeds, respectively. Tubers survived winter temperatures well when buried in the soil. When dipped in paraffin tubers survived up to four years in storage.
