Seed priming effects on seed quality, stand establishment and yield of direct seeded crops: A review

Abstract

Seed priming can be employed to reduce the duration of germination, to synchronize germination, to improve germination rate and to improve field stand of low-quality seeds. Seed priming helps to develop the embryo before germination with increasing α-amylase activity, and the content of fructose and glucose, and with reducing sucrose content. Total sugar content of primed seed was higher than non-primed seeds. Germination of soybean seed lot stored for 16 months improved by priming treatment from 10.0 to 50.5%. Priming treatment of soybean seeds stored more than 12 months also reduced T₅₀ by 0.3 to 1.0 days. Rapid and uniform emergence increases the stand establishment which influences better growth tend to better yield. Priming influences the emergence of seedling and stand establishment and it has a subsequence impact on yield and yield attributes. In general, plant population at harvest was closely related with emergence percentage of seed and plant population was positively correlated with seed yield.
