Seeds of Lupinus luteus, L. angustifolius and L. albus (1 determinate and 1 indeterminate cultivar of each) each harvested in 1996 and 1997, respectively, were separated into three specific density categories: light, heavy and very heavy with NaH2PO4×H2O. They readily germinated in the laboratory and have since grown into normal, healthy plants. Ecological Framework for Lupinus arcticus The table below shows the species-specific information calculated from original data (BEC database) provided by the BC Ministry of Forests and Range. Porsild and co-workers convincingly showed that a seed of the arctic lupine (Lupinus arcticus), stored in a lemming burrow since the Pleistocene, could still be germinated. The aim of the study was to evaluate the vigor and viability as well as to determine and compare the contents of selected protein fractions of white lupin (Lupinus albus L.) seeds stored for 26 years at temperatures of -14°C and +20°C.The seeds stored at -14°C germinated in 86.3%, while the seeds stored at +20°C did not germinate at all.

These seeds were recovered from an ancient rodent In 1967 it caused a stir when the seeds of this species were discovered in ancient lemming burrows dating back to the Pleistocene; the seeds were germinated and they produced plants, causing them to be declared the oldest viable seeds ever discovered. These seeds were recovered from an ancient rodent Ecology. In view of these studies and the investiga- tions made by @dum5 on the presence and age of viable seeds in Danish soils, Ester Creek placer mine west of Fairbanks, Alaska, Seed life (can be stored, short shelf-life, long shelf-life): Seeds are long-lived in nature and subsequently have a very long shelf life when frozen.
