Response of wheat genotypes to osmotic stress in terms of seed germination and growth of seedling
To compare the wheat genotypes in terms of seed germination and growth of seedling under osmotic stress conditions, a laboratory experiment was conducted using a completely random design with factorial arrangement. The wheat genotype (G) consisted of eight genotypes numbered as (G1) 9103, (G2) 9116,...
