This paper reports the typical characteristics of daily variation of cane and fruit diameter of vine tree in several fruit developmental stages.<BR>The results of this study are as following.<BR>(1) The fruit diameter shrunk in the day time and swelled at night just like the daily variation of cane diameter in the young, fruit-developmental stage. It was estimated that these phenomena were caused by the deficit of water content in the day time.<BR>(2) The characteristics of the daily changes of the diameter of cane and fruit, varied depending upon the several stages of development. This shows there is competition of water between the fruit and other organs even in a vine tree.<BR>(3) It was thought that the water did not easily come out of the ripening fruit and not was delivered to the other organs. Cane diameter shrinkage lasted continuously after the II stage of fruit development.
