摘要
以浙江省市售玉米种子为研究对象,测定种子含水量、净度、发芽率、病虫感染率、品种纯度等指标。结果表明,供试的68个玉米品种,有13个品种种子为不合格种子,合格率为80.9%;其中糯玉米种子合格率为84.2%,甜玉米种子合格率为61.1%,普通玉米种子合格率为100%。此外,从包装标注分析,共有12个品种种子包装标注不规范,种子标签合格率为82.4%;其中糯、甜、普通玉米种子包装标注合格率分别为81.6%,72.2%和100%。最后,对提高种子质量的途径和方法进行了探讨。
Seed moisture content, purity, germination percentage, pest and disease infection rates, varietal purity of 68 maize cuhivars in Zhejiang Province were tested in this study. The results showed that 13 cultivars were not quali- fied and the qualified rate was 80. 9%. The qualified rates of waxy maize, sweet maize and normal maize were 84. 2% , 61.1% and 100% , respectively. In addition, there were 12 maize cuhivars which did not reach the stand- ard of the package label, and the labeling qualified rate was 82.4%. The labeling qualified rates of waxy maize, sweet maize, normal maize were 81.6% , 72.2% and 100%, respectively. Finally, the improvement methods of seed quality were also discussed.
