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 Boreal**Research Institute proposes to develop and prototype two integrated technologies (priming and pelleting of**native seeds) to enable commercial-scale direct seeding of native boreal species in forest reclamation**operations. Seed priming is a method by which seeds are stimulated to imbibe water such that the metabolic**processes of germination begin. Seed pelleting is a technique by which seeds are encased in a coating. For**agronomic 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 many**undergo dormancy after maturation. Seed dormancy is often overcome by stratification and/or scarification**pretreatments. Although stratified seeds cannot be pelleted because they will lose viability quickly, seed**priming in combination with pelleting may be an alternative for native boreal seeds as priming will awaken the**seed 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 this**study is to assess germination and emergence of boreal native species in response to a combination of seed**priming and pelleting treatments. The project combines laboratory and greenhouse studies to develop priming**and 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 and**emergence and 2) achieve faster, more complete vegetative cover which, in turn, provides early erosion control**and 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填海作业的高昂成本，石油和天然气（O＆G）**行业有动力进行创新和引入优化北方种子使用的技术。 Boreal **研究所提议开发和原型两种综合技术（**本地种子的启动和颗粒），以在森林回收**操作中实现本地北方物种的商业规模直接种子。种子启动是一种刺激种子以吸收水的方法，使得代谢**发芽过程开始。种子颗粒是一种将种子包裹在涂层中的技术。对于**农艺作物，在广泛应用这种实践的情况下，结果是生产的速度和较高的产量。种子休眠通常是通过分层和/或疤痕化**预处理的。尽管分层种子不能迅速失去生存能力，但种子**与颗粒结合使用可能是本地北方种子的替代方法，因为底漆会唤醒**种子，但在“预先燃烧的”状态下，直到重新使用。**迄今为止。这项**研究的目的是评估北方本地物种的发芽和出现，以响应种子**启动和颗粒处理的结合。该项目结合了实验室和温室研究，以开发启动**和颗粒方法和特定于每个优先级本地北方物种的方法和技术。启动和沉淀物进行原型型和测试以用于森林开垦时，**将为工业和中小型企业提供新的多功能工具。
