摘要
以8个种源大红袍花椒1 a生实生苗为试材,采用盆栽法,测定了干旱胁迫条件下各种源花椒叶片相对含水量、可溶性蛋白质含量、丙二醛含量、超氧化物歧化酶和过氧化物酶活性,应用隶属函数法综合评价了不同种源花椒的抗旱性。结果表明:干旱胁迫程度不同,各种源花椒抗旱性强弱各异,各种源抗旱性强弱排序为:汉源花椒>涉县花椒>韩城花椒>凤县花椒>武都花椒>平顺花椒>泰安花椒>循化花椒。
One year old seedlings of prickly ash from 8 locations were pot-culture with different levels of water conditions to investigate their drought resistant performance by measuring related parameters, including leaf relative water content, soluble protein content, MDA content, SOD and POD activity. The drought resistance was comprehensively evaluated by membership functions. Differences were found among the prickly ash plants from 8 locations in drought resistance, and with an order of Hanyuan 〉 Shexian〉 Hancheng 〉 Fengxian〉 Wudu 〉 Pingshun 〉 Tai＇an 〉 Xunhua.
