1. The analysis of the shoot height growth of Phyllostachys edulis A. et C. Rivi$\acute{e}$re which stand is growing at the middle part of South Korea is presented in the present paper. The shoot height was carefully measured twice a day, 10 am and 4 pm. With this, six hours from 10 am to 4 pm is regarded as day-time-length and 18 hours of the rest as night-length. 2. The measurement were made in 1954. The very young shoots were classed into three diameter groups basing at the ground surface level to see the the afterwards influences of shoot size on height growth. 3. The hourly mean height growth in day time was higher than that in night time. The standard deviations and coefficients of variations of the daily growth of the shoot are presented in Figures 2 and 3 respectively. 4. The hourly mean height growth of the shoot by diameter groups and by day and night period are presented in Fig. 4 and 5 respectively. 5. The growth percentages of the shoot by diameter groups and by day and night is graphed in Fig. 6.
