果实成熟期间,细胞内部成分发生一系列变化,表现在出现颜色、结构和风味的改变。这些变化对于发展果实的最佳品质是必需的。采收后离开了植株母体的果实,仍然由活细胞组成,其细胞还进行着一系列的生理活动.然而这些活细胞已不能像采前一样从其植株母体获得赖以生存的营养物质,从遗传学的观点看,必然导致衰老和死亡。研究果实后熟的目的,在于延长采后果实的寿命及改善其品质。要达到这一目的,有必要研究促使细胞老化或衰老的生理生化变化,以控制细胞的衰老.
During fruit ripening, a series of changes occur in the internal components of the cells, showing changes in color, structure and flavor. These changes are necessary to develop the best quality of the fruit. After harvesting, the plant leaves the fruit of the plant mother and still consists of living cells whose cells undergo a series of physiological activities. However, these living cells can no longer obtain the nutrients they need from their plant mother Genetics point of view, will inevitably lead to aging and death. The purpose of studying fruit ripening lies in prolonging the life span of postharvest fruits and improving their quality. To achieve this goal, it is necessary to study the physiological and biochemical changes that promote cell aging or aging to control cell senescence.
