种子中的贮藏营养物质是其播种后生根发芽和苗期生长所需的唯一养料及能量。贮藏营养物质的种类及其在种子中的分布状况,既影响到种子的生理特性、耐藏性和加工品质等方面的问题,又是反映其饲用价值大小的依据和可能被利用的优良性状的依据。因此,了解牧草种子不同组成部分的化学成分,一方面可以使我们按不同用途而确定其利用价值;另一方面能帮助我们更深入了解其生理机能而科学地进行贮藏保存,尽量减少和避免在贮存中遭受 The storage of nutrients in seeds is the only nutrient and energy necessary for germination and seedling growth after sowing. The types of stored nutrients and their distribution in the seeds not only affect the physiological characteristics, storage resistance and processing quality of the seeds, but also reflect the basis of the feed value and the fine traits that may be utilized The basis. Therefore, understanding the chemical composition of the different components of forage seeds allows us to determine its value for different purposes. On the other hand, it helps us to understand its physiological functions in a more scientific and scientific manner, minimize and avoid Suffered during storage
