内容記述(抄録等)
It is well known that there have been generally three different fields for the study on the coloration in flowers, that is, the morphological, colorimetrical and biochemical. These studies, however, have been so far unconnected, and the literature which deals with the exact relationship among these studies is scanty, while the mechanism of coloration seems to be clarified by the synthesis from the results of these studies.
The present study was designed to throw some light on the interrelationship between the results of colorimetrical and biochemical investigations.
It was shown in a previous paper (Hiura & Nakaji, 1967) that there were colorimetrical and physiological differences in the reaction for the higher temperature (23℃) between the outside and the inside of the same petal.
In the present report, further observations on the influence of temperature on coloration by using five cultivars are described, together with some connections between the colorimetrical and biochemical investigations.
