在未成熟果实中,细胞膜系统形成通透屏障,将水解酶与底物分隔开;果实进入后熟呼吸跃变期,膜酶活性升高,不饱和亚麻酸酯化为膜磷脂的作用加强,改变膜的组分.膜上不饱和组分的增加,提高了膜的流动性,对溶质的通透增加.人们通常以测定植物组织外渗液的电导率来表示细胞膜结构与功能受损伤的程度.随着香蕉、大蕉、粉蕉果实后熟衰老的发展,果肉细胞膜系统降解.本试验是研究香蕉、大蕉、粉蕉果实常温贮藏时间与果肉的离子泄漏之间的关系,以寻找一种简单的方法,确定香蕉、大蕉、粉蕉果实的有效贮藏时间.
In immature fruits, the cell membrane system forms a barrier that separates the hydrolases from the substrate; the fruit enters the post-ripening respiratory phase and the membrane enzyme activity increases, and the effect of unsaturated linoleic acid esterification into membrane phospholipids is enhanced , Change the composition of the membrane.Organic components increase the membrane to improve the mobility of the membrane, increasing the permeability of solute.People usually determine the conductivity of plant tissue exudate to the membrane structure and function damage With the development of banana, plantain and banana fruit ripening and aging, the cell membrane system of fruit pulp was degraded.This experiment was to study the relationship between the storage time of banana, plantain and banana fruit at room temperature and the ionic leakage of pulp Look for a simple way to determine the effective storage time for banana, plantain, and banana fruits.
