Title: Study on Physiological and Genetic Changes of Maize Aging Seeds
Abstract: The paper deals with the physiological and genetic changes of two maize seeds (Mo17,478) in their aging course.The results showed that conductivity of the seeds that were treated with hot water of 58±1℃ increased with treating time;the relationship between dehydrogenase,amylase activities and germination index were positively significant respecvtively;the three bands of esterase in Mo17 seed disappeared after aging 30 minutes.the two bands of esterase in 478 seed disappeared after aging 25 minutes.the chromosomal aberration percentage was higher in seeds with lower viability.
