摘要
Abstract
[Objective]The purpose was to compare three methods for determing rye seed vigor, and confirm to its suitable determination method.[Method]Three commonly used methods for determination of seed vigor, TTC method, the red ink method and the ultraviolet absorp tion spectrophotometry, were used to determine rye seeds' vigor, and distiller water method as control.[Result]The results show that there was no significant difference in determining rye seeds' average germination rate between TTC method and the control. The average germination rate obtaining by the red ink method was 10. 13% higher than that of the control, and there was a significant difference between them. The light absorption value of extracts of rye seed after immersed in 8 h under 260 nm had a good correlation with its seed vigor when using ultravio let absorption spectrophotometry determining its seed vigor, which reflected the rye seeds'vigor in a large degree.[Conclusion]The study pro vides a theoretical basis for production, storage and examination of rye seeds.关键词
