This project was started in the summer of 1932 when it was felt that a knowledge or the germination behaviour of weed seeds, would enable the Division of Botany of the Central Experimental Farm, Ottawa, Canada, to complete the life history of many weeds. As considerable work has already been done on the effects of burial, these weed seeds were stored in bottles and in envelopes and kept in a laboratory under ordinary conditions of heat and light, etc. By periodically testing these seeds for germination it was hoped that specific differences in viability and changes in germination capacity due to age and mode of storage would be noted.
