Due to problems concerned with environment pollution in urban areas, the city dwellers’ social demand for urban green space is ever more increasing. The purpose of this investigation is to define the relationship between the Ornamental Linum usitatissimum L. seed germination and temperature for effective use of the seed. The petri-dish (90 mm in diameter) was covered with two sheets of filter papers and 50 Ornamental Linum usitatissimum L. was layered for four times. After then, 10ml of distilled water was supplied. Then, the sprouting test was conducted in chamber where the temperature was controlled at 5, 10, 15, 20, 25, 30 and 35°C. The light was adjusted to 12 hours. The source of light was 1341㎛ol・m -2 s -1 by using fluorescent light and halogen. The germination growth was investigated on two day term after the radicle projected by 3 mm. The investigation stopped when there was no further germination growth for seven days. The finding was that the final sprout growth rate was 80% at 5, 10, 15, 20, 25 and 30°C, while it was 70% at 35°C. In the optimal temperature investigation that leveraged normal distribution function standardized at the reciprocal of T50, the temperature was found to be 12~13°C, and the sprout growth rate was 80% within the range of 5~30°C.
