小麦品系研究。在水培养条件下，对携带额外5E(b)染色体或5E(b)染色体取代5D或5D染色体的中国春进行耐盐性筛选。先前报道的5E(b)添加系的耐受性得到证实，两个替代系在175 mol/m(3) NaCl环境下的存活率高于添加系和“中华春”亲本。并讨论了其耐换性较好的原因。
Lines of Triticum aestivum cv. Chinese Spring carrying an additional chromosome 5E(b) from Thinopyrum bessarabicum or having chromosome 5A or 5D replaced by chromosome 5E(b) were screened in hydroculture for tolerance to salt. The previously reported tolerance of the 5E(b) addition line was confirmed and the two substitution lines were shown to have a higher level of survival in 175 mol/m(3) NaCl than both the addition and the 'Chinese Spring' parent. Reasons for the better tolerance of the substitutions are discussed.
