NAJADACEAE
“Potamogeton spp. …pondweed.. the results from the five species … indicate that seeds of Potamogeton germinate readily if first subjected to several months of cold storage in water without first allowing them to dry. Seeds stored in water without chilling germinated very slowly and irregularly. Seeds stored in water for 5 months at room temperature and then chilled of 39 days a 1-3C gave good germination within 10 days. Dry seeds showed almost no germination. The seeds with thin pericarps do not withstand drying but usually die. Those with a thick boy pericarp, upon drying, enter a long dormant period. Such seeds, when subsequently placed in water, germinate very irregular. Seeds of all five species were cut open after 5 months of dry storage. Only two gave any germination, P. pectinatus, 21 per cent and P. americanus {P. nodosus}, 19 per cent”
