Abstract:
In order to find the cauliflower genetic integrity of physiological and biochemical change rule,to provide the basis for crop germless collection and preservation work.With three varieties of cauliflower as test materials,after aging treatment was conducted to study the seed germination rate，germination potential，hydrogen peroxide enzyme (POD)，super oxide dismutase (SOD) activity，malondialdehyde (MDA) content，soluble sugar content and conductivity value changes.The results showed that seed germination rate and germination energy were significantly decreased；POD activity，SOD activity and MDA decreased，a significant increase in soluble sugar content and conductivity value as the lengthen of aging treatment time.By the correlation analysis，different kind of genetic integrity of the optimal evaluation，POD activity，SOD activity，soluble sugar content and conductivity value could be used as the genetic integrity of cauliflower evaluation.
