Effect of salicylic acid (SA) pre-treatment on total cis-zeatin (cZ), trans-zeatin (tZ), and isopentenyladenine (iP) types of Hordeum vulgare L. ‘Ince-04′ plant leaves and roots under control or saline conditions (150 and 300 mM NaCl). Values are mean ± SE (n = 6). The data with different letters in the same column at superscript are significantly different (p < 0.05).
