A systemic seed treatment can be taken up into shoot tissues during early corn seedling growth. However, the pathway that a systemic compound is taken up, either from seed or root uptake to shoot tissues is not fully understood. To study the single contributions of seed pathway and root pathway for the uptake and translocation of imidacloprid seed treatment, two methods were developed: A seed treatment method and a growing media/hydroponic solution delivery method. The seed treatment method employed a live and dead seed separated with plastic wrap to provide a barrier. The growing media/hydroponic solution delivery method quantified the capacity for uptake by seeds and roots.

玉米幼苗早期生长过程中，吡虫啉通过种子途径和根途径吸收和转运。

在玉米幼苗早期生长期间，可以将系统性种子处理吸收到芽组织中。但是，尚未完全了解从种子或根部吸收到摄取组织的全身性化合物吸收的途径。为了研究种子途径和根途径对吡虫啉种子处理的吸收和转运的单一贡献，开发了两种方法：种子处理方法和生长培养基/水培溶液递送方法。种子处理方法采用用保鲜膜分开的生死种子来提供屏障。生长介质/水培溶液的输送方法量化了种子和根吸收的能力。
