在幼苗生长早期阶段，对 0、100、150 和 200 mM NaCl 水平的 24 种小麦基因型进行了耐盐性筛选。比较每个基因型的幼苗在盐水条件下的生长情况，以对照值的百分比表示。实验在带有尼龙网的塑料碗中进行，将种子放在上面进行发芽。将碗在 25 ± 5 o C 的培养箱中避光保存 72 小时，然后暴露在 4000 勒克斯的光照强度下进行光合作用。 192小时后收获幼苗并记录它们的芽和根长度以及干重。结果表明，小麦基因型 V-8001、LU26s、Bhittai、C-228、KTDH、KTDH-22、DS-17 在发芽和幼苗阶段对所研究的大多数生长参数都具有耐受性。
Twenty-four wheat genotypes were screened for salt tolerance at an early seedling growth stages at 0, 100, 150 and 200 mM NaCl levels. Seedlings of each genotype were compared for their growth under saline conditions as a percentage of the control value. Experiments were conducted in plastic bowls with nylon net over which seed were placed for germination. The bowls were kept in an incubator at 25 ± 5 o C in dark for 72 hours then they were exposed to 4000-lux light intensity for photosynthetic activity. Seedlings were harvested after 192 hours and their shoot and root lengths and dry weights were recorded. Results indicated that the wheat genotypes V-8001, LU26s, Bhittai, C-228, KTDH, KTDH-22, DS-17 are tolerant at germination and seedling stage in most of the growth parameters studied.
