为选育耐盐亚麻品种,采用不同浓度中性盐(NaCl)、碱性盐(NaHCO3)和混合盐(NaCl/Na2 CO3/NaH‐CO3)溶液对16份亚麻品种进行萌发期耐盐性鉴定。结果表明:中性盐胁迫下,黑亚19和双亚9发芽率最高,双亚12、黑亚14和黑亚17长势较好;碱性盐胁迫下,黑亚19和美若琳发芽率最高,黑亚17、Agatha和Di‐ane长势较好;混合盐胁迫下,黑亚19和双亚14发芽率最高,Agatha、美若琳和Diane长势较好。综合上述结果,亚麻黑亚19在萌发期的耐盐能力最强,其次是 Agatha和黑亚17;高浓度盐胁迫下不同品种间发芽率的变异程度较大,可作为亚麻耐盐品种筛选评价的标准;不同亚麻品种对中性盐和碱性盐的耐受能力不同。
為選育耐鹽亞痳品種,採用不同濃度中性鹽(NaCl)、堿性鹽(NaHCO3)和混閤鹽(NaCl/Na2 CO3/NaH‐CO3)溶液對16份亞痳品種進行萌髮期耐鹽性鑒定。結果錶明:中性鹽脅迫下,黑亞19和雙亞9髮芽率最高,雙亞12、黑亞14和黑亞17長勢較好;堿性鹽脅迫下,黑亞19和美若琳髮芽率最高,黑亞17、Agatha和Di‐ane長勢較好;混閤鹽脅迫下,黑亞19和雙亞14髮芽率最高,Agatha、美若琳和Diane長勢較好。綜閤上述結果,亞痳黑亞19在萌髮期的耐鹽能力最彊,其次是 Agatha和黑亞17;高濃度鹽脅迫下不同品種間髮芽率的變異程度較大,可作為亞痳耐鹽品種篩選評價的標準;不同亞痳品種對中性鹽和堿性鹽的耐受能力不同。

In order to breed flax varieties with salt tolerance ,the salt tolerances of 16 flax varieties were studied under different concentration of neutral salt (NaCl) ,alkaline salt (NaHCO3 ) and mixed salt (NaCl/Na2 CO3/NaHCO3 ) stress at germination stage .The results showed that the germination rate of Heiya 19 and Shuangya 9 were the highest under neutral salt stress and Shuangya 12 ,Heiya 14 and Heiya 17 grew better .The germina‐tion rate of Heiya 19 and Meiruolin were the highest under alkaline salt stress ,Heiya 17 ,Agatha and Diane grew better .The germination rate of Heiya 19 and Shuangya 14 were the highest under mixed salt stress and Agatha ,Meiruolin and Diane grew better .In short ,the germination rate of Heiya 19 was higher than others un‐der neutral salt stess ,alkaline salt and mixed salt stresses followed by Agatha and Heiya 17 .Additionally ,the variation range of germination rate between different varieties under those stresses was very obvious ,especially under the high salt concentration ,which could be the evaluation criteria of flax salt tolerance .The tolerance to neutral salt and alkaline salt were different among flax varieties .
