Abstract:

The aim of this study was to investigate the effects of glycerol (GL) and salicylic acid (SA) on freezing tolerance of Iranian Petunia (Petunia hybrida). For this purpose, a factorial experiment based on completely randomized design with three replications was conducted under controlled conditions. The first factor was temperature (0 and -4 °C) and the second factor was spraying with anti-stress compounds (24 hours prior to freezing) consisting of control (distilled water), salicylic acid (75 and 150 mg per liter), glycerol (0.1, 0.25, 0.5 and 1 percent) and the combined treatment of 150 mg/l SA+ 0.25% GL, 150 mg/l SA+ 0.5% GL, 200 mg/l SA+ 0.25% GL and anti-frost trade agent with concentration of 4 percent. The results of this study showed that under freezing stress conditions, SA and GL reduced the percentage of visual damage and electrolyte leakage and increased concentration of proline, and total carbohydrates, total phenols and antioxidant activity as compared to control plants. The percentage of visual damage in plants treated with 150 mg/l of SA + 0.5% GL at -4 °C was 3.33%, while the percentage of visual damage of control plants and those treated with anti-frost trade agent were 57.61 and 22.88 percent, respectively. The highest proline concentration was obtained from application of 150 mg/l of SA + 0.25% GL at -4 °C temperature. The results of this study showed that the use of SA and GL reduced the freezing-induced damage in Iranian Petunia through the improvement of physiological indices.

Brassinosteroid biosynthesis and signalling in Petunia hybrida

Brassinosteroids (BRs) are steroidal plant hormones that play an important role in the growth and development of plants. The biosynthesis of sterols and BRs as well as the signalling cascade they induce in plants have been elucidated largely through metabolic studies and the analysis of mutants in Arabidopsis and rice. Only fragmentary details about BR signalling in other plant species are know...

Efficiency of Foliar Application of Humic Acid on Improve Absorb of K than Na and Salt Tolerance in Petunia Hybrida L.

Salinity is a major limitation ecological factor for plant development in arid and semi-arid regions. The ionic imbalance, deficiency of nutrients and degradation of plant metabolites are caused by saline conditions, are affected by the reduction ratio of potassium (K) then sodium (Na). In this research foliar applications of humic acid (HA) for improve the absorption of K under salt stress was...

The S-Ribonuclease Gene of Petunia hybrida

To determine the ability of isolated S-locus promoter sequences to direct organ-specific gene expression, we used microprojectile bombardment to introduce chimeric S-allele/&glucuronidase genes into different tissues of Petunia hybrida for transient expression. Histochemical staining showed that S-locus/B-glucuronidase fusions were expressed in pistil, ovary, and petal tissue. No expression of ...
