Abstract

This study was carried out to evaluate the effects of indole acetic acid (IAA) and ABSCISIC ACID (ABA) on the TUBERIZATION in potato (CV. Agria) under greenhouse conditions. The potato mini-tubers (without any infection) were planted in pots containing pasteurized soil. The 4 weeks-old plants (7-8 leaves) were treated by spraying the foliage with 0, 5 and 10 μM (IAA) and with 0, 2.5 and 5 μM ABA weekly for 3 weeks. The results showed that application of IAA decreased the leaf area, but application of ABA increased the leaf area. With increasing concentrations of both hormones also increased the leaves numbers and tubers numbers. In addition, by increasing the concentration of ABA reduced the shoot weight and tuber weight. The results showed that total CHLOROPHYLL and CAROTENOIDS increased in leaves with increase in IAA applied, but they are reduced by increasing ABA levels. Also, by increasing IAA, polyphenol oxidase and peroxidase activities in leaf is a downward trend, while with increasing ABA, the activity of these enzymes is a upward trend. It seems that the influences of hormones AUXIN and ABSCISIC ACID on the TUBERIZATION in potato as an antagonistic effect however, this effect is not completely (100%) and depends on applied concentrations of hormones, conditions and growth stages and plant organs examined.
