Priming and Pelleting Native Boreal Seed for Land Reclamation

鉴于严格的监管标准和高昂的回收作业成本，石油和天然气(O&G)**行业有动力创新并引入优化使用北方种子的技术。北方研究所提议开发两项综合技术(引种和造粒)并制作原型，以便能够在森林开垦作业中对北方原生物种进行商业规模的直接播种。种子引发是一种刺激种子吸收水分，从而开始萌发的代谢过程的方法。种子丸化是一种将种子包裹在包衣中的技术。对于广泛应用这种做法的农艺作物来说，其结果是更快的产量和更高的产量。**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**在成熟后经历休眠。种子休眠通常通过层积和/或剥离**预处理来克服。尽管分层种子不能丸化，因为它们很快就会失去活力，但种子**与丸化相结合可能是北方原生种子的替代方案，因为引发会唤醒**种子，但会将其保持在“萌发前”状态，直到重新滋润。**到目前为止，还没有已知的研究集中在原生种子和丸化的耦合引发上。这项研究的目的是评估北方本土物种对种子引发和丸化处理的组合反应的萌发和出苗。该项目将实验室和温室研究相结合，以开发针对每一优先北方本土物种的引种**和丸化方法和技术。**引种和丸化的组合有可能1)部署均匀萌发和**出苗的种子，2)实现更快、更完整的植被覆盖，这反过来又提供早期侵蚀控制**和创造微型场地。引爆和造粒在森林开垦中原型和测试后，**将为工业和中小企业带来一种新的、多用途的工具。

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.
