Abscisic acid and cytokinin spraying effect on cation contents in two cultivars of wheat (Triticum aestivum L.) under drought stress

In order to evaluate the effects of appilcation of cytokinins and abscisic acid on two varieties of wheat (Pishgah and MV-17) under drought stress, a split splitplot experiment based on completely randomized block design with three replications, was carried out. The measured traits included the following cations: estimation content of Na, Ammonium, K, Mn, Ca, Mg, Fe and Zn in plants. Results showed that drought stress had a significant effect at the 1% level on all contents of cations (except for ammonium at 5%). There were significant differences between varieties on Na and Zn content at the 1% level and ammonium and Fe at 5% level. The results also showed that Na and ammonium in drought stress and other measured elements in normal conditions were more than those of other treatments. Varieties were different at uptake of Na, ammonium, Fe and Zn which variety of Pishgam uptake Na and ammonium less than that varieties and also uptake Fe and Zn more than it.
