玉米种子在贮藏过程中,由于呼吸作用会消耗营养成分,从而降低种子的发芽率。呼吸强度主要受水分和温度的影响,同时也是种子霉烂和生虫的主要因素。经多年实践,对玉米种子安全越夏,模索出了几点有效的做法。 一、降低种子水分。玉米种子的胚占整个种子重量的11.5％,含油量占83％。由于胚大,含油量高,吸湿性强,呼吸作用旺盛,因而容易生霉。玉米种子在粮食作物中是最难贮藏的种子。但是,含水量适当的种子特别是含水量在13％以下时,对环境条件的忍耐能力很强,因此,降低种子水分,保 Corn seeds in the storage process, due to respiratory effects will consume nutrients, thereby reducing the seed germination rate. Respiration intensity is mainly affected by water and temperature, but also the main factors of seed rot and pests. After many years of practice, the safety of the summer corn seed, the model obtained a number of effective practices. First, reduce seed moisture. Embryos of maize seeds account for 11.5% of the total seed weight and oil content of 83%. Due to large embryo, high oil content, hygroscopicity strong, strong respiratory effects, which is easy to mold. Corn seeds are the most difficult seeds to store in food crops. However, seeds with appropriate water content, especially those with a water content of less than 13%, are highly tolerant of environmental conditions and thus reduce seed moisture
