种子是内含生命活力种质基因的活体。因此贮藏种子就是延长种子寿命,保持强活力水平,并保持固有的种质基因为共同目的。但也各有侧重,在农、林生产作为生产资料的种子,其贮藏之主要目的,在于为生产提供具有高产潜力的种子,因而着眼点在强活力水平上。但作为长期保存种质资源来说,首先着眼于保存固有种质基因的延续性而不发生变异,因伴随老化、劣变过程常有染色体畸变发生,作为种质保存 Seeds are living organisms that contain vitality germplasm genes. Therefore, the storage of seeds is to extend the seed life, to maintain a strong level of vitality, and maintain the inherent germplasm gene for a common purpose. However, each of them has its own focus. The main purpose of the storage of agricultural and forestry production materials as seeds of production lies in providing seeds of high productive potential for production, and thus focusing on the level of strong vitality. However, as a long-term preservation of germplasm resources, the first focus on preserving the continuity of the inherent germplasm gene without variation occurs because of aging, deterioration often chromosomal aberrations occur as germplasm preservation
