【摘要】 利用HP34970A数据采集仪和计算机联用,测定了13种蔬菜活组织的冰点温度,利用PR-101型折光仪测定了蔬菜可溶性固形物含量。结果表明,蔬菜可溶性固形物含量(X)和冰点温度(Y)是高度负相关(r=-0.9007),其回归方程为蔬菜组织冰点Y=-0.2419X-0.3358。13种蔬菜活组织均有典型的冰点曲线。更多还原

【Abstract】 The freezing points of 13 cultivars of vegetables were measured using a HP34970A data collector and contents of soluble solids were measured using a PR-101 (0 -45% )refractometer. The results show that there is a high negative correlation between soluble solids and freezing point(r = -0.9007, p <0.05). A mathematical model is created to demonstrate this relationship( Y = -0. 2419X -0. 3358,7 Stands for freezing point;X Stands for soluble solids). All the tissues of the 13 vegetables have typical freezing point curves.更多还原
