Abstract/Contents:"In this paper, the abilities of three kinds of plant growth regulators (GA3, 6-BA, and NAA) to break the dormancy of Zoysia matrella underground stems in in vitro culture were studied. Both 6-BA and GA3 could significantly promote germination of dormant buds, but the pathways were different. 6-BA promoted the differentiation and growth of young leaves in the buds resulting in more green leaves per bud. There was no significant difference among three 6-BA treatments of different concentrations for overall affects. GA3 significantly promoted bud elongation with affects quite good for 10 and 100 mg/L treatments, but there was no increase in the number of green leaves per bud. Low and medium concentrations of NAA (1 and 10 mg/L) showed definite positive effects in breaking the dormancy of buds, but a high concentration (100 mg/L) showed quite a strong inhibition effect. NAA did not show any effects on root development. The research shows that the sprouting of underground dormant stems of Z. matrella may be subject to the joint regulation and control of gibberellins and cytokinins."
