Effects of seed priming on the germination properties of A. hookeri, an important subtropical vegetable in Korea, were tested in Petri dishes and soil conditions. In the Petri dish, the effects of two priming solution s, calcium chloride (CaCl2) and polyethylene glycol (PEG), and five priming times (6, 12, 18, 24, and 48 h) were evaluated. The results indicated that both CaCl2 and PEG priming enhanced the germination of A. hookeri, whereas PEG priming resulted in a higher germination percentage, energy, rate, and time to reach 50% germination, compared to the control and the CaCl2 priming. We further investigated whether seed priming had the same effect on A. hookeri germination in the soil. For this experiment, we selected two priming conditions that showed the best result for each group in a Petri dish by observing germination properties and initial growth characteristics. We found that both priming solutions positively affected the germination and early-stage growth of A. hookeri, although CaCl2 priming had a more potent effect. These results suggested that seed priming can be effectively used for improving the germination properties of A. hookeri, even as its effect can differ depending on the environment of seed germination and growth.
