Improving sorghum seed vigor by priming

Sorghum (Sorghum bicolor L. Moench) is the fifth most important cereal that is widely used for food, feed, and industrial purposes. Sorghum is cultivated mostly in the central and eastern parts of Indonesia. Sorghum seed viability and vigor influence its productivity by affecting crop growth and stand establishment. Invigoration can also be called conditioning or priming, and is one method that could enhance seed germination in the soil under abiotic stress. Some priming methods are hydro priming, osmopriming, and matrix conditioning. This paper will discuss research on sorghum priming which showed that many priming techniques could improve germination performance, speed of germination, and emergence uniformity.
