The Effects of Seed Priming with L-glutamine and L-arginine Amino Acids in Pepper Seeds

Abstract

Seed-priming is a physiological technique of seed hydration and drying to enhance the germination. Seed priming treatments can be used to achieve even and earlier sprouts. A popular seed-priming practice which helps the seeds germinate faster is hydro-priming. Other studies have shown that seed priming with α-arginine promotes growth in sunflower. Pepper seeds germinate slowly and the aim of this study was to assess the effects of seed priming with α-glutamine and α-arginine amino acids in pepper seeds grown in different fertilization scheme. During the evaluation it can be concluded that seed-priming treatment with α-arginine and double distilled water speeds up the sprouting. At some variants, it was proven that α-glutamine seed-priming was inefficient. It was also found that fertilization schemes influence the germination and root growth in the following year.
