| 摘要: |
| 用抗寒性不同的黄瓜品种，在子叶期和三片真叶期，研究了不同低温胁迫、低温胁迫不同时间以及不同渗透时间对叶片电解质渗出率的影响。结果表明：子叶期幼苗在一３℃低温下处理 １８ ｈ、渗透 ９０ ｍｉｎ，是用电导法鉴定黄瓜品种抗寒性的适宜条件，三片真叶期与子叶期的鉴定结果一致。 |

| Abstract: |
| The effect of low-temperature stress,stress time-length and the soaking
time after the stress on electrolyte Leakage of leaves of cucummbr seedllings at the
cotyledon phase and the 3 rd-leaf age were studied among different chilling-resistant cultivars.The results indicated that the treatment for 18 hours and soaking for 90 min.under low temperature of -3℃ were the optimum conditions for evaluationg cucumber
chiling-resistance by electrical conductivity method at cotyledon age of the seedling.The
results at the cotyledon phase are in agreement with the ones at the 3rd leaf age. |
