@article { , title = {Seed priming enhances early growth and improves area of soil exploration by roots}, abstract = {Introduction: Seed priming has been conducted for centuries with growth advantages reported for a variety of different crops. Previous work has suggested priming does not offer a yield advantage despite an increased early growth if grown under ideal conditions. However, how these advantages unfold in regards to early root development is largely unknown. Results: We observed accelerated germination speed in primed seeds regardless of applied seed enhancement technology i.e. coating or pelleting. Additionally, we found significant differences in lateral root development in primed seeds vs non-primed seeds. Furthermore, we recorded an increase in volume and surface of embryo and perisperm indicating a distinct morphological change during the germination process of primed seeds compared to non-primed seeds. Conclusions: We attribute the enhanced early plant development in primed seeds to increased root development and thus enhanced volume of the soil resource mined for nutrients. This improvement can be detected four days after emergence within the root system throughout the early plant development despite an early transition from seed reserves to soil based growth. The understanding of below ground root architecture characteristics can improve the selection of appropriate seed enhancement technologies and seedbed management practices.}, doi = {10.1016/j.envexpbot.2018.11.003}, issn = {0098-8472}, journal = {Environmental and Experimental Botany}, note = {12 mo. embargo.
