Evaluation of Seed Germination of Barley Grown after Priming with Leaf Extract of Moringa and Aqueous Garlic Extract

Abstract

A pot experiment was designed to determine the effect of seed priming on the germination of barley seeds in the winter season. Seed priming was done by using the leaf extract of Moringa at different concentrations (100%, 50% and 10%v/v) for 24 hours, and aqueous extract of ginger and tap water for different intervals of time (6, 12 and 24 hours). The experiment was continued for ten days with nine seed priming treatments. The results showed that maximum seeds germinated on day nine in all treatments. Whereas the highest germination of seeds was observed when seeds were primed with an aqueous extract of garlic for 24 hours and when seeds were primed with 100% concentration of Moringa leaf extract for 24 hours. The lowest seed germination was observed when seeds were primed with an aqueous extract of garlic for 6 hours. These results showed that Moringa leaf extract and aqueous garlic extract can be used to prime barley seeds to improve germination.
