What is a SRA analysis?

The SRA analysis is a supporter in seed testing. The SRA is the next generation analyzer to replace the Q2. It provides a fast and accurate measurement of single seed respiration that may be correlated to batch quality. Depending on the species, an analysis takes 10 to 72 hours. The result is an easy determination of dead, dormant and germinating seeds. Although the SRA analysis does not provide specific information about abnormalities in seedlings, it delivers fast and accurate information about homogeneity and vigor related parameters of seed batches. In addition, the SRA analysis is excellent for determination of differences between (individual) seeds and seed batches in comparison trials.

The SRA is based on optical oxygen detection technology and includes different temperature zones and modern software for machine control and data acquisition. With this technology, a large number of individual seeds can be measured simultaneously. The SRA test can be used for different purposes such as the determination of the basic quality (homogeneity) of a seed batch, determination of changes in seed properties after seed treatments, measurement of vigor related issues and parameter calculations in seed priming, etc. You are welcome to ask us to explain all possibilities.



The SRA test has many applications:
– measurement device to determine the viability of seeds
– simple control over seed processes
– prediction of applicability of priming methods
– support in cultivation programs
– results in 10-72 hours
– simple and fast check of seed maturation
– checking of bacterial and fungal infections of seed
– homogeneity testing
