果皮或种皮是种子的天然保护膜,它可以有效地抵御恶劣环境和防止病害的侵入。目前,人们还常利用杀菌剂来处理玉米、大豆种子以防治土壤传染及种传染的真菌和细菌性病害,提高保苗数量。但人们是否可以为种子包上具有更好保护作用的人工膜呢?美国衣阿华大学种子科学中心的两位科学家 JoeBurris 和DenisMcGee 已就种子包衣方法这一问题进行了两年研究。种子病理学家McGee 在研究中没有使用农药,他们正着眼于研究可以使种子避病的包衣。目前,他们的研究还处于试验阶段,在玉米种子利用多聚膜包衣已取得良好的结果。一些多聚膜在避免玉米萌发早期真菌侵染方面与使用克菌丹同样有效。
Peel or seed coat is a seed natural protective film, it can effectively resist the harsh environment and prevent disease invasion. At present, people often use fungicides to deal with corn, soybean seeds to prevent soil infection and fungal and bacterial diseases, and increase the number of seedlings. But can one package the seeds with better protective membranes? Joe Burris and Denis McGee, two scientists at the University of Iowa Seed Science Center, have conducted a two-year study on the seed-coating method. McGee, a seed pathologist, did not use pesticides in the study, and they are looking at the coatings that can make the seeds avoid the disease. At present, their research is still in the experimental stage, and good results have been obtained in the coating of corn seed using the multi-layer coating. Some polymeric membranes are as effective as using captan at avoiding early fungal infestations of corn.
