作物遇到0℃附近低温时,有时会发生生育障碍,象番茄、柑桔这类亚热带性作物,特别易受影响.即使对低温抗性较强的温带作物,温度突降时也会受害.已知这类反应和激素系列有关.据报导,游离酸(ABA)能增强耐冷性,赤霉素能减弱耐冷性.本试验在于验证ABA能否缓和低温对黄瓜的危害.
Crops are sometimes exposed to low temperatures around 0 ° C, and sometimes fertility disorders occur. Subtropical crops such as tomatoes and citrus are particularly susceptible, even in temperate crops with low temperature resistance. This type of response is known to be involved in the hormone family, and free acid (ABA) is reported to enhance cold tolerance and gibberellins to reduce cold tolerance.This experiment is to test whether ABA can alleviate the cold damage to cucumber.
