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 ** 广泛采用这种做法的农作物，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。种子休眠通常通过层积和/或划痕预处理来克服。虽然分层的种子不能丸化，因为它们会很快失去活力，但种子 ** 引发结合丸化可能是原生北方种子的替代方案，因为引发将唤醒 ** 种子，但将其保持在“发芽前”状态，直到重新湿润。到目前为止，还没有已知的研究集中在耦合引发的天然种子和造粒。本研究的目的是评估北方本地物种对种子引发和造粒处理组合的发芽和出苗反应。该项目将实验室研究和温室研究相结合，以开发针对每一个优先的北方土著物种的引发 ** 和造粒方法和技术。引发和造粒相结合有可能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，这反过来又提供了早期侵蚀控制 ** 和微型网站的创建。当在森林开垦中使用时，** 将为工业和中小企业提供一种新的、多功能的工具。
