[Studies on seed quality evaluation technique and grading rules of Cistanche deserticola]
1Institute of Medicinal Plant Development, Chinese Academy of Medical Sciences/Peking Union Medical College, Beijing 100193, China.
Objective:
To establish a seed quality evaluation technique system and quality grading rules for Cistanche deserticola.
Methods:
We used stereomicroscope, microphotography and image analysis system, tetrazolium method to measure, analyze and evaluate the size, thousand kernel weight, plumpness, embryo rate and viability of Cistanche deserticola seed. Then we used SPSS 11.0 statistical analysis software to analyze the seed viability and related indexes of another 55 batches.
Results:
Seed size was significantly correlated with thousand kernel weight, but wasn't correlated with seed viability. However, grain plumpness was negatively correlated with seed viability. Seed quality was not determined by seed size but by seed viability and grain plumpness.
Conclusion:
Seed viability, thousand kernel weight and grain plumpness are significant indicators of seed quality and they can be took in the granding rules of Cistanche deserticola seed.
