豆科绿肥科杂1号耐盐性鉴定（简报）

Salt Tolerance Identification of Leguminous Green Manure Crop Keza No.1

摘要: 以NaCl致死浓度和耐盐等级为评价指标, 对豆科绿肥科杂1号苗期的耐盐性进行鉴定。结果表明:科杂1号致死浓度为230mmol·L-1, 盐处理后其SPAD值为23.95, 表明科杂1号属于中度耐盐品种。

Abstract: Taking NaCl lethal concentration and plant chlorophyll content measured using a chlorophyll meter spectrophotometer as evaluation index, salt tolerance of leguminous green manure crop Keza No.1at seedling stage was evaluated.The results indicated that the lethal concentration of salt for Keza No.1was 230 mmol·L-1. SPAD value after NaCl treatment was 23.95.In a word, Keza No.1was relatively salt-tolerance.
