Field Storage of Vegetables in Cold District (II)

Artificial Inducement of Freezing Damage

Abstract

The freezing damage to the vegetables for four sorts being investigated under an artificial atmosphere in winter of Obihiro using drip as a criterion, multiple regression of drip on item (or initial moisture content), temperature (minimum) and time were calculated. Relationship between drip on temperature and time showed linearity from the orthogonal polynomials for Chinese cabbage and radishes, while quadratic curves on temperature were obtained for cabbage and carrots. The decreasing order of freezing damage is as follows: Chinese cabbage, radishes, cabbage and carrots, and this fact agreed much with the results reported in previous paper.
