In order to establish a convenient, economical and short time-consuming system which can be applied for the research of apoptosis in rice cell, rice cell （cell mass） system was established by the grinding method, and then was induced by 500 mg/L salicylic acid, 250 mmol/L CaCl2, ZnCl2 and MgCl2 respectively. The results were determined by gel electrophoresis. This study showed that DNA fragments smaller than 1 kb appeared in the system induced by salicylic acid for 6 h, and the number of small fragments increased substantially with the treati...
