采用“糠尿分析试纸法”测定20种十字花科蔬菜种子生活力,并与TTC法及实验室发芽率对照进行相关分析。结果表明, “糠尿分析试纸法”所测种子渗出液中葡萄糖含量与种子生活力、室内发芽率呈负相关;种子渗出液中葡萄糖含量越高,生活力越弱,发芽率越低。采用该法测定种子生活力快速简便。 The viability of 20 species of cruciferous vegetable seeds was determined by the “Method for the analysis of bran analysis paper”. The correlation analysis was made between the TTC method and laboratory germination rate. The results showed that there was a negative correlation between the glucose content of seed exudate and the viability of seeds and germination rate of the seeds in the exudative solution of “branded urine test strip”. The higher the glucose content in seed exudates, the weaker the vitality, the lower the germination percentage . The method of determining the viability of the seed is quick and easy.
