RT Journal Article SR Electronic T1 Ethephon effectively breaks seed dormancy without stratification in the globally rare northern blazing star Liatris novae-angliae JF Native Plants Journal JO NATIVE PLANTS JOURNAL FD University of Wisconsin Press SP 101 OP 105 DO 10.3368/npj.24.2.101 VO 24 IS 2 A1 Tillman, Dylan A1 Connolly, Bryan A1 Windmiller, Bryan A1 McElroy, Cara YR 2023 UL http://npj.uwpress.org/content/24/2/101.abstract AB Northern blazing star (Liatris novae-angliae (Lunell) Shinners var. novae-angliae [Asteraceae]) is a perennial herbaceous plant endemic to the northeastern US, specifically the states of New York, New Jersey, Connecticut, Massachusetts, Rhode Island, New Hampshire, and Maine. The species is globally rare and listed as a protected species in all regions in which it occurs. State agencies and environmental nonprofits have been working to increase northern blazing star populations through re-introductions at historic locations or establishment at new sites. This species is typically propagated by seed. The standard germination protocol is to cold stratify seeds in moist media for 60 d. Here we show that the plant growth regulator ethephon can be used to break seed dormancy more rapidly while inducing similar germination rates to cold stratification in Liatris novae-angliae.
