Melon (Cucumis melo L.) fruits was respectively treated with solutions of 500 mg L^-1 of 4-CPA (4-chlorophenoxyaceticacid) and 20 mg L^-1 of CPPU (2-chloro-4-pyridyl-N-phenylurea) and then cell size and sugar accumulation in the fruit were investigated. The mean number of cells larger than 200 μm for each rectangular parallelepiped (7-mm long sample serially collected beginning at one end of the 10-mm wide strip removed from the 10-mm thick disk at the maximum transverse diameter of the fruit to the opposite end. Designated as a sample) of the 4-CPA and the CPPU-treated fruits on the 40th day after anthesis (DAA) was 1.4 times higher than that of the control. The mean number of cells smaller than 200 μm per sample of the CPPU-treated fruits on the 55th DAA was 6.5 times higher than that of the control. Mean sucrose content per sample of the 4-CPA and the CPPU on the 55th DAA was 1.7 times as much as that of the control, and the mean glucose and fructose content of the CPPU-treated fruit on the 55th DAA was the highest, being 1.5 times higher than that of the control. Thus, it might be considered that the earlier increase in the number of larger cells in the 4-CPA- and the CPPU-treated melon fruits is related to a larger content of sucrose, and the increase in the number of small cells during the latter period of the CPPU-treated fruits participates in the largest content of glucose and fructose.
