| Zoysia japonica is one of the types of clonal plants,it is a kind of turfgrasswidely used in our country as a kind of clonal plants. Unlike non-clonal plants amajor feature of clonal plants is between ramets through physiological integrationwill be linked site, sharing resources among the various ramets Water is the lawnplanted significant environmental aspects, because the larger the lawn, there is oftenuneven turf grass irrigation. So explore the integration of the mother plant andramets had Zoysia japonica clones heterogeneous conditions when water, whetherthe water can occur with far-reaching theoretical significance and meaningfull.In this experiment, the sub-strains of Zoysia japonica mother plant connected tothe experimental materials, Control groups using the gravimetric method of fieldcapacity, varying degrees of water stress Specifically two homogeneous groups ofwater, The mother plant and the sub-strains both were irrigated, the mother plant andthe sub-strains both were in arid; Heterogeneity of water conditions in two groups:The mother plant in arid and arid sub-strains of The mother plant irrigation irrigationsub-strains. By studying the heterogeneity of water conditions on The mother plantclonal plant, plant growth promoter physiological indicators of changes in thefluorescence study of photosynthetic, Moisture conditions discussed heterogeneoussub-strains of The mother plant clonal plant moisture transfer case. The mainfindings are as follows:1. Heterogeneous moisture conditions, if the plant adequate of water, then thewater content of the root and the leaf was smaller under the effects of drought stress.Anyway, if the sub strains of sufficient water, plant water content is affected bydrought stress is larger, the plant in sufficient water condition, will lead tophysiological integration between sub strains.2. Water heterogeneous conditions, is transferred from the maternal to child linewater can guarantee the chlorophyll content of sub strains are not affected, due tomaternal and child were found with physiological integration, so supply twophotosynthesis substances are reduced, so the two common weakened photosynthesis. From the photosynthesis index, heterogeneous conditions by theplant to plant physiological integration is very few, or no integration.3. By the optical quenching coefficient qN transform can explain theheterogeneity of moisture conditions of chlorophyll fluorescence kinetics parameterswill be affected by the moisture transfer of non water heterogeneous conditions, canprove that the heterogeneous soil moisture condition of Zoysia japonica parent tophysiological integration sub line is there, but the influence on fluorescencemechanism, need to be more thorough research.4. The antioxidant enzymes and proline content results can be obtained, whenclonal plant in water heterogeneous conditions, if the stock sufficient water canproduce physiological integration to sub line, if the sub strains of sufficient water,integration between is not obvious from the maternal. The MDA increase wasmembrane damaged results, the process is irreversible, the plant to the physiologicalintegration sub strains should occur under stress, namely MDA has increased, so thecontent of MDA will not be connected with the water sufficient stock of.In summary, Zoysia japonica as clonal plants, when maternal sub strains inmoisture conditions under sufficient water if the heterogeneity of plant, the plant willhappen physiological integration and sub strains, this integration can ensure theindex line most are guaranteed in normal growth condition. At the same time as themother plant integration to sub strains, material content in the plant will be reduced,so the plant growth also has certain influence. If the plant is under drought stress,sub strains have little or no to plant physiological integration... |
