EFFECT OF MAGNETIZED WATER ON ESTERASE ISOZYMES IN THE LEAVES OF TOMTO PLANT

Jin Kunzhen;Wan Guanghui and Qiu Jianao(Department of Biology,Northwest University,Xi’an 710069)  
Esterase isozyme patterns revealed with disc-poly-acrylamde gel electrophoresis were studied in the leaves of Lycopersicom esculentum ″Zhao Kui″.The electrophoregram observed in different stages of development from seedJing to full bloom in tomato plants showed that their patterns and electrophoretic mobility were similar.But in the treatinment with the magnetized water,there were distinct differences in esterase activities and zymogram pattens in comparison with the con- trol.More isozyme bands and taller scanned peaks were observed in the treatment with 1000 GS and 1200 GS,and in the treatment with the 1400 GS there is one band less than the control;nev- ertheless,these changes did not exsist in the second generation which had not treated with mag- netized water.Determination of phosphorus content in the leaves showed that it was much higher in the treatmtnt with magnetized waterk,especially in the treatment with 1000 GS.It is therefore suggested that magnetized water mayhe activates the regulator gene by means of zymogen activa- tionor catises a small mutations that can be repaired in structural gene to control the esterase isozyme and phosphorus metabolism.
