Abstract
Abstract
A hydroponics experiment was conducted to compare effect of Fe-deficiency on concentration, uptake, translocation of Fe, Zn, Mn in some plants. A completely randomized block design in triplicates was conducted in research greenhouse. Seven plants with different Fe-efficiency contained two bread wheat genotypes (Triticum aestivium L. CVs. Backcross Roshan and Qods), triticale (X. Triticosecale Cv eleanor), dent corn (Zea Mays L. CV. S.C704) and two safflower (Carthamus tinctorius L. CVs Arak2811 and Koose) were grown in a nutrient solution at two Fe levels of 5 and 50 µM Fe EDTA. The most tolerant and the most sensitive of plants to Fe-deficiency were bread wheat (Qods genotype) with 125% Fe-efficiency and safflower (Arak2811) with 3.5% Fe-efficiency, respectively. A significant and positive correlation was found between the Fe-efficiency and Zn, Fe and Mn contents and root to shoot translocation of Fe among the studied crops. Large variation was found among the studied crops in shoot and root Zn, Fe and Mn content. The Qods and cross back Roshan wheat genotypes accumulated greater Zn, Fe and Mn in their shoots compared to other genotypes. Higher uptake and root to shoot translocation of microelements in the Fe-efficiency genotypes is an important aspect for biofertilization programs with the aim of improving crop quality.
