Effects of Storage on Seed Dormancy and Survivorship in Black Cohosh (Actaea Racemosa L.) and Goldenseal (Hydrastis Canadensis L.)

Albrecht, M. A. and McCarthy, B. C. Seed Science and Technology 35:414-422. 2007.

Medicinal herbs indigenous to eastern deciduous forests are increasingly cultivated in forest gardens for economic and cultural purposes, yet little information is available on how post-harvest seed storage effects survivorship and germination. In this study, seeds of the medicinal woodland herbs, black cohosh (Actaea racemosa L.) and goldenseal (Hydrastis canadensis L.), were subjected to a factorial combination of storage conditions over a 360 d period to quantify seed survivorship and dormancy levels. Our results corroborate a prior study - that. indicates seeds of both species are morphysiologically dormant (MPD) and require a sequence of warm -4 cold temperatures for complete dormancy-break.
