Abstract:In order to investigate the effect of iron nutrition on growth and development of common wheat at seedling stage, 86 wheat germplasms from Shandong Province under normal culture and iron deficiency treatment were used as material to study the number of roots , length of main root, dry weight of root, dry weight of shoot and root /shoot ratio.Their evolution rules of different times were also studied .The results showed that except root length, the other 4 traits were significantly different between iron deficiency and con -trol treatments.The root number, root length and dry weight of shoots were also significantly different between varieties.Furthermore, the variance and stress index analyses were performed , and the results indicated that most wheat varieties showed decrease in root number and shoot dry weight and increase in root dry weight and root /shoot ratio under iron deficiency treatment .This study also found that the wheat varieties such as Linmai 4, Weimai 8 and Shannong 27 had strong iron tolerance, so they could be used for genetic improvement of wheat iron nutrition.
