异源细胞质小麦耐盐性的研究

以粗厚山羊草（Ａｅｇｉｌｏｐｓ ｃｒａｓｓａ）细胞质小麦为材料，采用组织培养，水培、模拟盐池等方法，研究细胞质对小麦耐盐性的遗传效应，结果表明：粗厚山羊草细胞质可以不同程度地诱发小麦耐盐性产生变异。不同核质组合细胞质效应有一定差异，表现出特定的核质互作关系。部分异质系细胞水平与植株水平的耐盐性表现一致，特别是（Ａｅ．ｃｒａｓｓａ）－鉴２６的愈伤组织和幼苗的耐盐性表现均最突出。返青期和成熟期的鉴定结

Studies of Salt Tolerance of Alloplasmic Wheat

Using Aegilops crassa cytoplasm wheat as test material, salt tolerance of alloplasmic wheat was identified by tissue culture, nutrient solution culture and artificial saline pond, from calli, seeding stage, recovering stage and mature period. The results showed Ae. crassa cytoplasm lines indicated the difference of salt tolerance in varying degree; the difference of cytoplasm effect among different nucleoplasm combinations showed certain nucleoplasm interaction relation. The salt tolerance of (Ae. crassa)-jian 26 was stronger than that other tested alloplasmic lines. The result demonstrated that at recovering date and at mature period indicated salt tolerance of alloplasmic lines was not only stronger than its nuclear parent but also over control variety. As compared with common wheat lines having strong salt tolerance were more proportions in tested alloplasmic lines. The study of alloplasmic wheat should be significant for breeding salt tolerance wheat
