水分胁迫对纽荷尔脐橙叶片脱落酸含量的影响

摘  要：本试验以纽荷尔脐橙为试验材料研究在不同的水分胁迫下，叶片中脱落酸(ABA)含量的变化。在其它条件均相同的情况下，分别以最大土壤含水量60%，40%，20%，为试验组，以CK（正常浇水）作为试验对照组。在柑橘苗木达到试验所设计的胁迫后，连续控制30天，然后运用液相色谱—质谱法对叶片中的ABA含量进行测定，试验结果表明随着土壤含水量的降低，纽荷尔脐橙叶片中ABA的含量逐渐升高。

Studies on abscisic acid content of Newhall navel orange leaves under water stress
Abstract: This experiment studies on leaf abscisic acid content (ABA content) changes of Newhall navel orange which is regarded as experimental material under various water stress. Under the circumstances of other conditions are equal, take the maximum soil water content as 60%, 40%, 20% respectively for the test group, while CK (normal watering) as the control group. After Tangerine nursery stocks reach the designed water stress, they will be under 30 days continuous control, after that the ABA content of leaves will be measured in the way of high—performance liquid chromatography. The results show that with the decreasing of water content, ABA content increased gradually. [来源：http://www.doc163.com]
