Abstract：Experiments were conducted to investigate the influence of temperature on the effect of chlorocholine chloride（CCC）controlling excessive growth of cucumber（Cucumis sativus L.）seedlings，by using 4 different day/night temperature conditions．The results showed that CCC treatments could not control the excessive growth of hypocotyls in environment condition of day/night temperature of 35 ℃/ 25 ℃．Under the day/night temperature of 28 ℃/18 ℃ or 25 ℃/15 ℃ environment，as the temperature decreased，the concentrations of CCC for seed soaking，which was needed for strong seedling cultivation，were reduced accordingly．The best controlling effect were gained by 2 000 mg?L-1 and 500 mg?L-1 CCC，respectively．When the day/night temperature was 20 ℃/10 ℃，the growth of seedlings were significantly inhibited by CCC treatments，and hypocotyls were shortened，while the control treatment was not spindling，thus soaking seed with CCC was unnecessary under this condition．
