| 摘 要： | 在4个不同昼夜温度条件下研究0、500、2 000、4 000、7 000 mg?L-1矮壮素浸种对黄瓜幼苗徒长的控制作用。结果表明：昼夜温度35 ℃/25 ℃，不同浓度矮壮素浸种均不能有效控制下胚轴伸长及幼苗徒长|昼夜温度28 ℃/18 ℃或25 ℃/15 ℃，随着温度的降低，黄瓜壮苗所需的矮壮素浸种浓度相应降低，且分别以2 000 mg?L-1和500 mg?L-1矮壮素浸种的效果最好|昼夜温度20 ℃/10 ℃，矮壮素浸种显著抑制幼苗的生长，下胚轴短缩，对照幼苗亦不徒长，说明此温度条件下不需要进行矮壮素浸种。

| 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． |
