Influence of seed priming on germination characteristics of sorghum (Sorghum bicolor L. Moench)

Abstract

Abstract Seed priming or invigoration is presowing treatments of improving germination aimed to reduce the time from sowing to emergence and improving emergence uniformity. Research on seed priming was conducted Indonesian Cereal Research Institute (ICERI) seed laboratory from January until March 2021 to evaluate the effect of seed priming on sorghum seed vigor. Seed quality parameters includes germination percentages, germination rate, shoot and primary root length, seedling dryweight, Sorghum seed variety of Suri 4 were used as seed material. Results showed that among the priming treatments that give positive effect on germination percentage, germination rate, seedling dry weight were priming treatment with KNO3 1.5%.
