为明确黄瓜的耐低温性及脱落酸（ABA）、生长素（IAA）、赤霉素（GA3）、腐胺（Put）、亚精胺（Spa）、精胺（Spin）含量对其生长的影响变化规律，选取耐低温性不同的6份材料9504，9506，9507，9511，9514，9517，进行低温处理，白天12℃，晚上8℃，每天光照处理7．5h，强度为30μmol（m^2·s）^-1，约合2000lx，共处理14d。结果表明，在常温下各内源激素含量差异不显著，经低温处理的含量均上升，差异均显著。相关分析表明，耐寒指数与处理后的全部激素含量的偏相关均呈正相关，但均未达显著水平。说明低温使黄瓜幼苗的生长受到一定程度的抑制，但能够通过调节自身的内源激素来减轻低温的伤害，维持植物体的正常生长及生理代谢功能，从而表现出一定的耐低温潜力。

In order to investigate change law of characteristics of cucumbers such as the chilling tolerance, ABA content, IAA content, GA3 content, Put content, Spd content, Spin content effect on growth, materials 9504,9506,9507,9511,9514,9517 were carried under low-temperature treatments, 12/8 ℃ in day/night, with 7.5 h everyday by the light intensity of 30 μmol· （ m^2· s） ^-1 （ or 2 000 lx） for 14 days, which were different in tolerance of low temperature. The results indicated that there was no significant difference for all endogenous hormones at normal temperature;but there was significant difference for other characteristics at low tempera- ture;all endogenous hormones content increased at the low temperature treatment. Correlation analysis showed that chilling tolerance was positively partial correlated with all endogenous hormones content. We could con- clude that the growth of cucumber seedlings were negatively influenced by low temperature stress, but the en- dogenous hormones could adjust themselves to avoid low temperature harms, which led to some tolerant ability of cucumber to low temperature conditions.
