用玻板直立发芽、温水浸种发芽以及电导法测定１０个结球甘蓝品种（组合）种子活力，并与田间出苗率进行比较分析。结果表明，玻板直立发芽法的发芽指数、活力指数和温水浸种的发芽率和发芽势以及电导法测定的电导率值均与田间出苗率呈显著或极显著相关，由此建立了５项指标与田间出苗率的直线回归方程。 The vitality of seeds of 10 cabbage varieties (combinations) was determined by standing and germinating with glass plates, soaking in warm water and germination as well as by conductivity method, and compared with the seedling emergence rate in the field. The results showed that germination index, vitality index, germination rate and germination energy of soaking in warm water and the conductivity measured by conductivity method were all significantly or extremely significantly correlated with the germination rate in the field, and thus five indicators Linear regression equation with field emergence rate.
