Abstract/Contents:"Studies were conducted to evaluate the effect of priming and preimbibition on germination of unscarified and KOH-scarified zoysiagrass (Zoysia japonica Steud.) seeds, respectively. Germination percentages at 35°C of seeds primed in KNO3 and Ca(NO3)2 were significantly higher than that of untreated seeds. The optimum conditions for priming unscarified seeds were in aerated KNO3 solution at 0.4 M for 4 days at 20°C. No additional benefit of GA3 on increasing germination was not found in seed priming with solution of KNO3 + GA3 or in seeds preimbibed with GA3 priming. Scarified seeds preimbibed with distilled water(DW) for 4 days at 20°C germinated higher and with fewer days to 50% of total germination (t50) than untreated seeds. Preimbibition with GA3 solution at 50ppm for 4 days at 5, 10, 15, and 20°C enabled up to 97% of seeds to germinate and reduced days to T50 about 1.1 to 1.2 days at 35°C. Especially, seeds preimbibed with GA3 had greatly higher germination and lower T50 than untreated or DW-preimbibed seeds at 30°C which is inadequate to germination in general. Preimbibed seed performance was unchanged after storage at room temperature for 50 days. Seeds preimbibed with GA3 had higher rate of seedling emergence and faster growth of shoot than untreated seeds after sowing at 30°C in growing medium in growth chamber."
