چکیده
In order to assess corn responses to zinc compounds and auxin (Indole Butyric Acid) foliar application in shoots and roots, a pot experiment was carried out in randomized complete block design in three replications. Results showed that, zinc and auxin increased auxin and abscisic acid concentration both in shoots and roots. Also, fresh and dry weight of shoot and root increased model to foliar application, because protein synthesis was increased. On the other hand, according to unusual case, auxin and ABA showed positive parallel variation both in shoot and root, but this relation was more noticable in shoots.
