“…N ative perennial grasses have many uses in agriculture, conservation, and landscaping. However, high‐quality seed for native grasses and other wild plants is difficult and expensive to produce (Dunne and Dunne, 2003; Cole and Johnston, 2006). Many native plants display active mechanisms of seed shattering that create a multitude of problems when these species are cultivated for seed (Berdahl and Frank, 1998; Kennard et al, 2002; Lemke et al, 2003; Bedane et al, 2005; Wang et al, 2008).…”

Many native grasses display seed shattering and other seed production problems. Basin wildrye [Leymus cinereus (Scribn. & Merr.) Á. Löve] and creeping wildrye [L. triticoides (Buckley) Pilg.] are perennial Triticeae grasses native to western North America. In this study, variation in the number of florets per inflorescence, percent seed set, seed mass, seed shattering, and seed dormancy was measured in clonally replicated multiyear field evaluations of 164 progeny derived from a backcross between a creeping × basin wildrye hybrid and a true creeping wildrye tester. Genomewide quantitative trait locus (QTL) scans detected independent gene effects for all five traits and one pleiotropic QTL, located on Triticeae homeologous chromosome group 6, associated with major seed shattering (43.1% R2, 26.9 log of odds likelihood ratio [LOD]) and seed dormancy (24.1% R2, 10.6 LOD) effects. We hypothesize that a dominant basin wildrye gene creates an abscission that promotes seed disarticulation but hinders seed development and seed ripening in the creeping wildrye backcross family. Alignments of Leymus chromosome 6 expressed sequence tag markers to the rice (Oryza) genome reveal well‐defined correspondence of Leymus wildrye and American wildrice (Zizania palustris L.) seed shatter QTLs.

Many small‐scale projects in Australia suggest that ground‐layer elements of ecosystems can be restored, but scaling up of grassland and grassy understorey restoration has not occurred to date. Paul Gibson‐Roy recently travelled through the USA, where well‐developed markets for restoration have created a large, financially viable native‐herbaceous seed production and restoration sector. Here, he shares his observations, which show how much about the USA situation can be a model and inspiration for Australian grassy ecosystem restoration.

“…Although native seed is increasingly available, quantity demanded still exceeds quantity supplied for many species (Loch et al 1996;McArthur and Young 1999;Dunne and Dunne 2003;BLM 2015). One would expect prices to rise in such instances until the market clears.…”

The increasing frequency of fires and the focus on energy development in the western United States have expanded need for reclamation of disturbed lands. Government policy significantly influences demand for native seed and prioritizes use of native plants to improve reclamation success. However, existing native seed supplies are inadequate for current reclamation needs. The U.S. Bureau of Land Management (BLM) seeks to implement policies that will increase the quantities supplied. We conduct laboratory market experiments to analyze the effect of different policies BLM might implement on price, quantity traded, and earnings, especially in light of BLM's role in the market as largest buyer. Four treatments are examined, combining forward (production-to-demand) or spot (advance production) delivery and constant (seller unit earnings are constant and known) or variable demand (seller unit earnings randomly adjusted without notice) under big buyer influence (four sellers, two small buyers, one big buyer). A fifth competitive treatment (four sellers, four buyers) with forward contracting and constant demand provides a benchmark by which to gauge big buyer effects on market outcomes. Results provide evidence that adoption of forward contracting or reduction in BLM's demand variability would increase seller earnings and native seed production. L'augmentation de la fréquence des feux et l'attention particulière portée au développementénergétique dans l'Ouest américain créent un plus grand besoin pour la remise enétat de terrains perturbés. Les politiques gouvernementales influencent significativement la demande pour les semences indigènes et priorisent l'utilisation de plantes indigènes pour accroître la réussite de remises enétat. Par contre, les approvisionnements en semences indigènes ne répondent pas actuellement aux besoins de remise enétat. Le Bureau of Land Management (BLM) desÉtats-Unis chercheà mettre en place des politiques qui augmenteront la disponibilité des semences. Nous menons des expériences de marché en laboratoire afin d'analyser les effets des diverses politiques qui pourraientêtre mises en oeuvre par le BLM en matière de prix, de quantité négociée, et de revenus, tenant compte du rôle de BLM sur le marchéà titre de principal acheteur. Quatre traitements sontétudiés, combinant la livraisonà terme (productionà la demande) ouà comptant (production anticipée), et la demande constante (les revenus a l'unité du fournisseur sont constants et connus) ou variable (les revenusà l'unité du fournisseur sont ajustés aléatoirement, sans préavis) sous l'influence de grands acheteurs (quatre fournisseurs, deux petits acheteurs et un grand acheteur).Un cinquième traitement compétitif (quatre fournisseurs, quatre 695 696 CANADIAN JOURNAL OF AGRICULTURAL ECONOMICS acheteurs), avec contratsà terme et demande constante, fournit une référence contre laquelle il est possible d'évaluer l'effet du grand acheteur sur les résultats du marché. Les résultats fournissent des preuves selon lesquelles l'adoption de contratsà terme...
