Abstract/Contents:"Water absorption and response to temperatures of seed germination of Zoysia japonica cv. Lanyin III, a new lawn grass variety, were studied. In addition, the seed characteristics of Lanyin were also compared with a most popular Chinese commercial lawn variety of Zoysia japonica cv. Shandong. The seed samples of Shandong included both breaking dormancy treated and nontreated. The results showed that the seed size of Lanyin was small with a 1000-seed weight of 0.308g, the amount of water uptake at the initial imbibition stage (IIS) of seed germination was much less than Shandong. For instance, the maximum amount of water uptake at IIS lasted 48h for Lanyin 72h for nontreated Shandong and 12h for treated Shandong, however, the rates of water uptake among the three tested samples were no big difference (34%~42%). The suitable temperatures for germination of Lanyin were the alternative temperatures of 15~35°C, 20~30°C and 20~35°C. At these test conditions, the germination speed (first count, 36%~46%) and final percentage (64%~72%) counted both higher than the other treatments, while, no seed germinated for nontreated Shandong sample under the all 7 tested conditions. The range of temperature suitable for germination of treated Shandong sample was narrower than the Lanyin, which were 15~35°C and 20~35°C. The length ratio of root/shoot of Lanyin measured both in laboratory and in field showed higher than the Shandong."
