Abstract/Contents:"'Anyang' (Zoysia japonica) is famed as a good quality warm-season grass in Korea. Its color, quality, and disease resistance are the most attractive parts among many zoysiagrasses. However, its ability of establishment is very low because of poor germination and low vigor of seed. 'Anyang' is a vegetatively propagated turfgrass until now. The main goal of this study is to improve 'Anyang' to seed propagation and evaluate priming systems in combination with fungicidal seed treatment in soil. Various seed priming treatments were tested to enhance final emergence under suboptimal temperature. Osmotic priming of turfgrass seeds (Zoysia japonica) using potassium salts (0.2, 0.4M KNO3) or sodium salts (0.2, 0.4M NaNO3) resulted in higher germination at 25 degrees. The inclusion of 50ppm GA3 was more effective on both germination rate and mean germination time than those without GA3. In addition to GA3, priming duration was most critical to increase germination rate as well as reduce mean germination time. Particulary, priming for 7, 9days [9 days] with GA3 regardless of salts dramatically promoted the germination rate by 37.6 ≅ 45.3% compared with the non-treated seeds, and also shortened the mean germination time by 3.3 to 4.1days [4.1 days] at suboptimal temperature (25 degress). The result of fungicide treatments indicate that methyl cellulose could affect zoysiagrass seed germination and fungicide combination (metalaxyl + toclofos-methyl) was more desirable on seed germination than that of fungicides treatment alone. In soil infested with the most serious pathogen in zoysiagrass, Rhizoctonia solani AG2-2, combined fungicides induced 80% emergence compare [compared] to 30% of control."
