一种测定两个收获时期(A_1和A_2)、三个大豆品种(Young,Centennial,Sharkey)的劣变种子的生理质量(生活力和活力)的方法被确定,并把它与标准萌发和种子外渗物pH测试相比较。种子外渗物pH测试法是一种根据种子外渗物从无色到玫瑰红色的颜色变化来预测种子葫发力的比色法。根据玫瑰红色的变化或者无颜色变化能明显地区分有生活力和死亡的大豆种子。根据外渗物pH测试的颜色变化预测萌发与标准萌发试验之间有密切关系。随着延迟收获时间,标准萌发与预测萌发的总体趋势相似。外渗物pH测试预测的萌发值与标准萌发都随着劣变期的延长而降低。在两个不同时期收获的三个大豆品种中预测的萌发值都比标准萌发高一些。
A method to determine the physiological quality (viability and viability) of poorer seeds at two harvesting stages (A_1 and A_2) and three soybean cultivars (Young, Centennial, Sharkey) was determined and compared with standard germination and seeds Extravasation pH test compared. Seed extravasation pH test is a colorimetric method for predicting seed gourd strength based on the color change of seed extravasation from colorless to rose red. According to rose red change or no color change can clearly distinguish between viability and death of soybean seeds. Predicting the Germination According to the Color Change of the Extravasate pH Test There is a close relationship between the germination and the standard germination test. With delayed harvest time, the general trend of standard germination is similar to that of predicted germination. The predicted germination value and standard germination of the extravasate pH test both decreased with the prolongation of the deterioration period. The predicted germination values were higher in the three soybean varieties harvested at two different times than the standard germination.
