| Abstract/Contents: | "Zoysiagrass (Zoysis japonica) is a herbaceous plant of the Gramineae. Since it has a fine texture and exceptional cold, drought tolerance, it is a very important warmseason turfgrass. But there still has a lot problems to establish turf by Zoysiagrass seed because of its strong dormancy. In this study, the quantity of abscisic acid (ABA) in Zoysiagrass seed and break dormancy of Zoysiagrass seed is discussed. ABA in dormant and non-dormant seed is determined during germination using a method of indirect enzyme linked immunosorbent assay. There are 4.533 µg ABA in seed coat and 2.40 µg ABA in grain per gram. The result also showed that the quantity of ABA in grain play an important role in seed dormancy, and quantity of ABA decreased when break dormancy. Exogenous hormone (Gibberellin and 6-Benzyl-aminop-urine) is used in dormant and NaOH pretreated Zoysiagrass seed. We find that, though exogenous GA has some effects in improving dormant seed germination rate, but germination rate still low. To break Zoysia grass seed dormancy completely, removing the stress of seed coat is very important, then, exogenous hormone enable the seed germination rate to reach its germination potential." |
