Na:K ratios of salt tolerance and susceptible varieties of wheat were measured. The Na:K ratio in wheat grain and straw above or below a particular level indicate the tolerance of wheat to salinity. The fact was confirmed by applying presoaking treatments of plant hormones to test susceptibility of varieties. On the basis of the results obtained in 2 pot experiments, the limit of the Na:K ratio of grain and straw of wheat for designating a variety as tolerant is less than 0.15 and less than 0.4 respectively, while this ratio at the tillering stage is 0.5.
