Komatsu city is one of the biggest carrot-producing districts in Ishikawa Prefecture. In this district, carrot seeds are sown at the beginning of August, and roots are harvested from November to December or from the thaw of the following spring. Many carrt roots have been recently found to have shiny white belt-like swollen patches running lengthwise under the epidermis. This has become a big problem for growers in this district. This disorder has been called "mimizubare-sho" in view of its similarity to inflamed scratches on the human skin. This paper reports the condition of "mimizubare-sho" in carrot roots, especially the roots bearing these shiny white belt-like patches running lengthwise.

Changes in characteristics of guinea fowl eggs during storage were investigated comparing with chicken eggs. Characteristics of eggs were measured after 0, 5, 10, 20 and 30 days in storage at 30℃. Guinea fowl eggs were smaller in weight, and larger in specific gravity than chicken eggs. In guinea fowl eggs, proportions of shell and yolk to total egg weight were higher, and proportion of albumen to total egg weight was lower than those in chicken eggs. The yolk-albumen ratio in guinea fowl eggs was 53.7%, and that in chicken eggs was 47.3%. Yolk index in chicken eggs decreased markedly from 0.412 to 0.143 during twenty days in storage. However, yolk index in guinea fowl eggs decreased slightly from 0.402 to 0.266 during the same period. Albumen index in chicken eggs decreased markedly from 0.086 to 0.033 during five days in storage. However, in guinea fowl eggs it was 0.146 on the day of collection, and was maintained at relatively high level until the twentieth day of storage when the value dropped down to 0.062. Haugh unit decreased remarkably in chicken eggs in the first five days; however, it decreased slightly in guinea fowl eggs.
