摘要：
Genotypic variation to zinc (Zn) deficiency in barley indicates that selection for Zn efficiency is possible. Sahara (Zn-efficient) and Clipper (Zn-inefficient) were evaluated at different Zn nutrition in soil and chelator-buffered nutrient. Zinc deficiency symptoms appeared first in Clipper and later in Sahara. At 0.8 mg Zn/kg soil, shoot and root Zn concentration and content were higher in Sahara than Clipper. The root:shoot dry matter ratio of genotypes increased as Zn application decreased. The 4th and 5th leaf elongation were depressed greater in Clipper than Sahara by Zn deficiency. The genotypes responses to Zn in solution and soil were consistent in all parameters except root growth. In contrast to soil, root drymatter was greater in Clipper than Sahara in solution under Zn deficiency. Shoot Zn concentration and content can be used in assessment of barley genotypes, and may be useful criteria in screening large genotypes aimed at developing molecular markers for Zn efficiency.
