摘要：

Saline hydroponic studies of cytogenetic stocks of wheat have shown that near isogenic lines carrying contrasting alleles Vrn (vernalisation requirement) or Ppd (photoperiod requirement) genes accumulate less sodium when the dominant allele is present. These dominant alleles also confer early flowering. The genetic control of response to salt stress is discussed with respect to Vrn and Ppd genes. The data suggest that both these genes have pleiotropic effects on sodium accumulation. Salt treatment did not appear to switch on any genes which control sodium accumulation and it is concluded that the intrinsic genetic make-up of the plant determines fitness under salt stress conditions.
