干燥是保持种子生命,延长种子寿命的重要措施。大多数树种的种子都要经过一个冬天的贮藏,到翌年春天或更长的时间才来播种。近年来,人们意识到林木结实的大小年现象对育苗、造林的速度和规模有着很大影响,需要趁种子丰年多采种,以供欠年之用。因此,采用球果干燥已成为发展林业生产的一个重要环节,而研究球果干燥的机理更有着重要的现实意义。一、种子与水分的关系水分是种子细胞内部新陈代谢作用不可缺少的介质,在种子的成熟和贮藏期间,种子物化性质和生化过程的变化,都与水分的状态及含量有着密切关系。 Drying is an important measure to maintain seed life and prolong seed life. The seeds of most tree species go through a winter storage and are sown in spring or longer the following year. In recent years, people realized that the size-wise phenomenon of tree growth has a great impact on the speed and scale of nursery and afforestation. It is necessary to take advantage of the abundance of seeds for the harvest of the year. Therefore, the use of dried cones has become an important part of the development of forestry production, and the study of the mechanism of confectionery has more important practical significance. First, the relationship between seeds and water Moisture is an indispensable medium for the internal metabolism of seed cells during seed maturation and storage, the physical and chemical properties of seeds and biochemical processes are closely related to the status and content of water.
