黄瓜种子在连续白光、蓝光、黄光及黑暗下能够萌发,红光及绿光的连续照射却抑制黄瓜种子的萌发。能萌发的光质下的种子中过氧化物酶活性随时间的延长而不断升高,至子叶张开后趋于稳定;抑制萌发的光质下的种子内过氧化物酶活力始终保持极低的水平。萌发的种子中蛋白质含量为规则变化,不能萌发的种子中蛋白质含量一直呈下降状态而最后趋于稳定。
Cucumber seeds germinated under continuous white light, blue light, yellow light and darkness. Continuous irradiation with red light and green light suppressed the germination of cucumber seeds. Peroxidase activity in seed germinated under light quality increased continuously with time, until cotyledon tended to be stable. The activity of peroxidase in seed which inhibited germination was always low s level. The content of protein in germinated seeds changed regularly. The content of protein in seeds that could not germinate decreased all the time and finally stabilized.
