In light of stringent regulatory standards and high costs of reclamation operations, the oil and gas (O&G)industry is motivated to innovate and introduce technologies that optimize the use of boreal seeds. The BorealResearch Institute proposes to develop and prototype two integrated technologies (priming and pelleting ofnative seeds) to enable commercial-scale direct seeding of native boreal species in forest reclamationoperations. Seed priming is a method by which seeds are stimulated to imbibe water such that the metabolicprocesses of germination begin. Seed pelleting is a technique by which seeds are encased in a coating. Foragronomic crops, where this practice is widely applied, the results are faster production and higher yields.Unlike many agricultural plant species, the majority of boreal native plant seeds are very small and manyundergo dormancy after maturation. Seed dormancy is often overcome by stratification and/or scarificationpretreatments. Although stratified seeds cannot be pelleted because they will lose viability quickly, seedpriming in combination with pelleting may be an alternative for native boreal seeds as priming will awaken theseed but hold it in a 'pre-germinated' state until re-moistened.To date, no known research has focused on coupling priming of native seed and pelleting. The objective of thisstudy is to assess germination and emergence of boreal native species in response to a combination of seedpriming and pelleting treatments. The project combines laboratory and greenhouse studies to develop primingand pelleting methods and techniques specific to each of the priority native boreal species.The combination of priming and pelleting has potential to 1) deploy seeds of uniform germination andemergence and 2) achieve faster, more complete vegetative cover which, in turn, provides early erosion controland the creation of micro-sites. Priming and pelleting, when prototyped and tested for use in forest reclamation,will result in a new, versatile tool for industry and SMEs.

鉴于严格的监管标准和高成本的复垦作业，石油和天然气（O&G）行业有动力创新和引进技术，优化北方种子的使用。北方研究所提议开发两种综合技术（本地种子的引发和造粒）并制作原型，以便能够在森林开垦作业中对本地北方树种进行商业规模的直接播种。种子引发是一种方法，通过这种方法，种子被刺激以吸收水分，从而萌发的代谢过程开始。种子丸化是一种将种子包裹在包衣中的技术。对于农业作物，这种做法被广泛应用，结果是生产更快，产量更高。与许多农业植物物种不同，大多数北方原生植物种子非常小，许多种子在成熟后经历休眠。种子休眠常通过层积和/或划痕预处理来克服。虽然分层种子不能丸化，因为他们会很快失去活力，种子引发结合丸化可能是一种替代方案，为本地北方种子引发将唤醒theseed，但保持它在一个'发芽前'的状态，直到重新wistened.To日期，没有已知的研究集中在耦合引发本地种子和丸化。本研究的目的是评估种子引发和丸化处理相结合的北方本地物种的发芽和出苗。该项目结合实验室和温室研究，开发针对每一种优先的北方原生物种的引发和造粒方法和技术。引发和造粒的结合有可能1）部署均匀发芽和出苗的种子，2）实现更快，更完整的植被覆盖，从而提供早期侵蚀控制和微型网站的创建。当在森林开垦中使用的原型和测试中，底漆和造粒将为工业和中小企业带来一种新的多功能工具。
