2011～2013年在山东共采集337个市售玉米杂交种子样品，测定其含水量、发芽势、发芽率等指标，并统计其种子包衣、包装及包装袋标识等信息。结果表明，近3年山东市售玉米杂交种在质量保证方面仍存在一些问题：破损（包括较大裂纹）种子较普遍，破损的样品数占同批总数超78．0％；发芽势和发芽率差异较大，分布范围分别为41．7％～100．0％和53．7％～100．0％。对此提出了提高、保证种子质量的3条建议。

From 2011 to 2013, 337 commercial maize seed samples were collected from Shandong Prov-ince.The indexes of seed moisture content, germination potential and germination percentage were detected and the informations of seed coating, packaging and packaging bag label, etc were censused.The results showed that the seed quality assurance of commercial maize hybrids in Shandong Province still presented a se-ries of problems.Damaged ( including larger crack) samples occupied over 78%;the differences between ger-mination ability and germination rate were significant, and the germination ability ranged from 41.7%to 100. 0%, while the germination percentage ranged from 53.7%to 100.0%.The ways and methods to improve and ensure the quality of maize hybrids were put forward based on the results.
