摘要：以美花兰幼苗为试验材料,研究了不同溶液胁迫对美花兰幼苗中过氧化物歧酶(SOD),过氧化物酶(POD)的影响。结果表明,使用静置12 h的自来水处理幼苗8 h后的SOD酶,POD酶活性与用Hogland营养液培养相同时间的2种酶的活性相接近;与用Hogland营养液相比,直接用自来水处理8 h后SOD酶,POD酶的活性分别降低了67.40%和66.19%。盐(1.8%NaCl),干旱(25%PEG-8000),低温(4℃)各处理8 h后SOD酶活力分别降低了8.84%,34.7%,22.41%;POD酶的活力分别降低了63.35%,30.80%,28.29%。结果表明,使用静置12 h后的水浇灌幼苗的效果较直接使用自来水效果好;美花兰对盐、低温均敏感且不耐旱。
In this paper, the seedling of C. insigine Rolfe was used to study the SOD, POD activities after different treatment. The results showed that the activities of SOD and POD under treatment by tap water which was placed 12 h was close to that watered by the Hogland; Compared with that watered by Hogland （named as CK） , the activities of SOD and POD watered by tap-water immediately were decreased about 67. 40% and 66. 19% respectively. In other experiments, the seedling of C. insigine Rolfe were treated 8 hours under the salt （1.8% NaCl）, drought（25%PEG-8000）,4℃ in the icebox respectively, compared to the CK, the activities of SOD were decreased about 8. 84%, 34. 7 %,22.41%, and the activities of POD were decreased nearly 63. 35%, 30. 80%, 28. 29 % respectively. The results give the reason why the tap-water which was placed for more than 12 hours was suitable for water the （2. insigine Rolfe seedling, and also indicated that the C. insigine Rolfe was sensitive to the salt and low temperature, and can not endure drought stress.
