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.
目的
建立肉苁蓉种子质量评价技术体系及质量分级标准。
方法
采用体视显微镜、显微摄影及图像分析系统、四唑法对肉苁蓉种子的大小、千粒重、饱满度、胚率及生活力进行测定、分析和评价。然后用SPSS 11.0统计分析软件对另外55批次种子的生活力及相关指标进行分析。
结果
种子大小与千粒重显著相关，但与种子生活力无关。然而，籽粒饱满度与种子生活力呈负相关。种子质量不是由种子大小决定的，而是由种子生活力和籽粒饱满度决定的。
结论
种子生活力、千粒重和籽粒饱满度是种子质量的重要指标，可纳入肉苁蓉种子分级标准。
