以7个冬青品种为试材,采用温室控盆法,研究了不同浓度NaCl((0、3.0、6.0、9.0 g·L-1)胁迫对其生长和生理影响,并运用隶属函数法综合评价冬青品种NaCl胁迫下的耐受性强弱,以期为冬青品种适生区域的确定提供参考依据。结果表明:1)冬青的盐害症状、死亡率和株高生长与胁迫天数和胁迫浓度显著相关;品种之间存在显著差异。2)相对电导率（Rce）和丙二醛（MDA）含量均与胁迫天数和胁迫浓度呈正相关;超氧化物歧化酶（SOD）活性和可溶性蛋白质含量均与胁迫天数和浓度呈负相关;而过氧化物酶（POD）活性除‘Blue Maid’,与胁迫天数呈正相关外,其它6个品种均随着胁迫天数的延长和胁迫浓度的提高呈先上升后下...

Seven Ilex cultivars were used as test materials.The influence of different concentrations of NaCl(0 g·L-1,3.0 g·L-1,6.0 g·L-1and 9.0 g·L-1)for 50 days on the growth and physiological characteristics of two-year-old cuttage seedlings of seven Ilex cultivars were studied by pot culture in the plastic greenhouse,and membership function method was used to evaluate the tolerance of Ilex cultivars under NaCl stress,in order to provide a reference for determining the suitable area of the holly variety.The results showed that,1)Symptom,mortality a...
