The Study Of Effects Of The Spatial Condition On The Growth And Physiological Characteristics Of Turf Grass

Dry seeds of Kentucky bluegrass Baron which were divided two, one treated by water, the other by Boric Acid, were carried by SZ-4 spaceship with Perennial ryegrass Derby Supreme dry seeds, then seeded and compared with seeds on the earth. In this Experiment, the seed of perennial ryegrass is the sub-1 generation. For the seeds, characteristics, including germination rate, tiller number and plant height were determined. Then Determine the Characteristics of the Drought Resistance on Turf grass. Compared with the comparison, the phenotype of plant had the differences should carry on isozymes analysis.The result indicated that, the spatial condition has the obvious effect to Kentucky bluegrass Baron which is treated by Baric Acid; the one treated by water has the longer bud and root than the seed without spaceship. But the spatial condition has the certain inhibitory action to the seed of perennial ryegrass in the sub-1 generation on germination rate; but the length of bud and the root has increased; and it is obvious to promote the plant height and tiller number, and there are many dwarfing plants. The function of the spatial condition on the drought resistance of turf grass is inconsistent; the analysis of the isozymes indicated that the spatial condition has the obvious effects on the enzyme belt quantity, and the enzyme belt depth of turf grass, which means the effects to the growth of the turf grass.By summarizing the effects in growth norms, we can find the different beneficial types of plants; one is that of high drought resistance, fast growth and higher tiller, the other is dwarfing plants, which are valuable for the production and the study of the breeding of turf grass.
