Mildew during storage of seeds is generally caused by dew condensation on the surface of the seeds, which causes the seeds to absorb moisture and increase moisture, causing the microorganisms to grow and multiply, causing the mold to become hot and mildew, resulting in the deterioration of the quality of the seeds, discoloration of the seeds, deterioration of taste, loss of viability or even loss And so on. A process and type of seed mildew 1.1 The process of seed mildew: Seed mildew is a continuous process, it has a certain stage of development. 1.1.1 The initial stage, that is, in the case of suitable environmental conditions, the surface of the micro-organisms attached to the use of secreted enzymes to start breeding activities. Seed mildew early characteristics, is the seed table
