Species recovery is hindered by lack of reputable propagation knowledge, challenges associated with seed procurement, and limited resources available locally for propagation. A suite of germination and sanitation studies were conducted to examine the effects of seed moisture content, cold stratification length, and chemical treatment on germination. No evidence supports that the odds of a seed germinating are statistically different among seed moisture content levels, cold stratification lengths, or sanitation treatments. Mean germination time (MGT) was unaffected by seed moisture content but was greater when seeds were subjected to ≥ 14-d cold stratification compared to unstratified seeds. MGT was also greater when seeds treated with a 10-min soak in 2:3, 5.25% sodium hypochlorite:water solution followed by a 30-min running water rinse were compared to untreated seeds. Treatment with a 1-h 3% hydrogen peroxide soak followed by a 1-h running water rinse significantly reduced seedborne fungi in comparison to untreated seed. Results suggest that P. occidentalis has non-dormant seed and does not benefit from the current practice of a pre-germination soak or from cold stratification, but a 1-h 3% hydrogen peroxide soak followed by a 1-h running water rinse can control seedborne fungi without compromising germination.","PeriodicalId":500620,"journal":{"name":"Native Plants Journal","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135401950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding long-term environmental adaptation of species and plant releases is critical for achieving persistent site restoration and rehabilitation. Idaho NRCS established a multi-species display nursery in the semiarid Snake River Plain at Orchard, Idaho, in 2004. The display nursery included 9 entries of bluebunch wheatgrass (Pseudoroegneria spicata (Pursh) Á. Löve [Poaceae]) and 4 entries of Snake River wheatgrass (Elymus wawawaiensis J. Carlson & Barkworth [Poaceae]), which were evaluated yearly for plant density from 2005 through 2008, and again in 2021. In this non-replicated case study, we found several bluebunch and Snake River wheatgrass accessions and releases adapted to local site conditions while not being of local origin. Our observations further support the commonly accepted belief that Anatone bluebunch wheatgrass is better adapted to lower precipitation areas than 'Goldar'. We did not see evidence that Snake River wheatgrass was more drought tolerant than bluebunch releases at the Orchard study site, but rather, we saw significant variation among releases or accessions of each species.","PeriodicalId":500620,"journal":{"name":"Native Plants Journal","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135401964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five extant populations are in Canada. One potential recovery strategy for S. diphyllum is to augment existing populations and (or) establish new populations via conservation translocation. While seeds are sold in the nursery trade, few studies have been published on ex situ germination and propagation. Predictions are that Canadian populations are genetically distinct from US populations, but no studies have tested for phenotypic differences between plants from these sources. We collected, stratified, and sowed seeds from 2 of the native Canadian populations and 3 commercial seed companies and grew them in a common garden. We achieved a germination rate of 53% for seed from Canadian populations and 44% for commercial seeds following 2 mo stratification at 25 °C (77 °F) and 2 mo at 4 °C (39 °F). Plants from 1 Canadian population grew faster, produced more leaves, differed in leaf and seed morphology, and had fewer trichomes than the plants of commercial origin. These results show that S. diphyllum can be propagated successfully from Canadian seed sources and that Canadian S. diphyllum populations are likely phenotypically distinct from commercial stock. Our findings will inform the development of a translocation strategy and set the stage for genetic analysis of these populations.","PeriodicalId":500620,"journal":{"name":"Native Plants Journal","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135401975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
