采用生物化学法（ 红四唑染色法） 快速测定玉米种子的生活力，再用常规的砂盘法发芽，得到相应的种子发芽率。回归分析表明，种子发芽率与生活力之间存在显著的相关性，红四唑染色法可用于种子调运过程对发芽率的估计
The biochemical method (red tetrazolium staining method) was used to measure the viability of maize seeds quickly, and then germinated by the conventional sand disc method to get the corresponding seed germination rate. Regression analysis showed that there was a significant correlation between seed germination rate and viability, and the red tetrazolium staining method could be used to estimate the germination rate
