油青菜心和黄瓜吸胀种子对高压静电场的反应

分别对吸胀的油青菜心和黄瓜种子进行不同场强相同时间和同一场强不同时间的高压静电场处理．测定了处理后的种子发芽势、脱氢酶和过氧化物酶活性、可溶性蛋白含量以及种子超弱发光．结果显示高压静电场处理显著提高种子活力，促进种子萌发．经高压静电场预处理的种子萌发后，种子的超弱发光较对照明显增强，并且种子超弱发光的变化与生理生化指标的变化具有明显相关性，表明超弱发光可作为一种准确、快捷、灵敏的物理指标，用于对种子最佳电场处理剂量的筛选．

Reactions of imbibed Chinese cabbage and cucumber seeds to high-voltage electrostatic field

The effect of high-voltage electrostatic field on the germinating energy, dehydrogenase and POD activities, soluble protein content and super-weak luminescence for Chinese cabbage and cucumber imbibed seeds treated with different dosages was looked at. The test results indicated that high-voltage electrostatic field had obvious effect in improving seed vigor and seed germination, and the super-weak luminescence of seeds treated with high-voltage electrostatic field became significantly stronger. The changes in super-weak luminescence, physiological and biochemical indices showed significant correlation, indicating that super-weak luminescence could be an accurate, fast and sensitive physical means in choosing the optimal electric field treatment dose for seeds.
