| Abstract: | The experiment of applying organic fertilizer, chemical fertilizer and the both to calcareous blade soil in which organic content was very low was carried out from 1993 to 1994. The conductivity of osmotic electrolyte and the catalase activity and the content of abscisic acid of endo-hormone, as wall as ultrastructure of palisade tissue and xylem were determinded under the condition of artifical simulated arid regime at different growth stages of soybean. Results indicated that under the condition of drought, organic fertilizer could relax ravages of drought, reduce the content of abscisic acid in soybean plant and the conductivity of osmotic electrolyte of leaf blade, raise the catalase activity of leaf blade, decrease the injury of cell envelope, and avail to delay senesence of soybean leaf blade, and cell wall of palisade tissue of leaf was increased in thick ness.The test result of regression correlation indicated that,under the condition of drought, the lower the conductivity of osmotic electolyte of leaf blade, the higher the catalase activity of palnt's leaf blade is, ralationship between these two is remarkably negative in correlation. Relationship between the content of abscisic acid of endo-hormone of leaf blade and the conductivity of osmotic electrolyte is possitive in correlation. |
