Foliar application of Indol Acitic Acid (IAA) and Gebirilic acid (GA3) as well as interaction effect on growth yield and some physiological compositions of Triticum plant grown under salinity conditions

Abstract

The present study aimed to investigate the effect of spraying with IAA and GA3 and the interaction between them on improvement the growth, yield and some biochemical and physiological characteristics of wheat plant (Triticum durum serf Triticum aestivum) of two cultivars, Mohamed Ben Bachir (MBB) and Hedab (HD), were growing under different concentrations of sea water salinity ( 10%, 30% and 60%) and the comparison plant control was also used.The results showed decreased continuously in plant length and yield (as spikes and 100 wheat grain weight), with increasing the concentrations of salinity during the growth period, compared with untreated plants. The concentrations of salinity used, has negatively effect on number of leaves and proliferate (first generation) and the leaf area of plant. On contrast, proline content was increased with increasing the concentrations of salinity, this revealed that the plant exhibited resistant to salinity. The spraying with regulators of growth used in the present study (IAA and GA3), showed significant effect on plant, in the extent of reducing the hurt effect of salinity on the vegetative measurements and some physiological components of plant.

Exogenously applied plant growth regulators enhanced the yield and quality attributes of wheat (Triticum aestivum L.)

“…Growth regulator having capable to improve metabolism and yield attributes of plants. Indole acetic acid and gibberellic acid significantly affects various attributes of plant growth and development (Gherroucha et al 2011) [8] . It is well known that the degree of leaf senescence is inversely proportional to cytokinin content, and exogenous application of kinetin helpful in increasing chlorophyll content as well (Sanaa et al 2006) [12] .…”

Leaf organic content variation of 2 durum wheat genotypes under water stress by applying phytohormone (IAA)

“…Studies have shown that plants pre-treated with IAA exhibited enhanced drought resistance (Almazroue, 2014). Foliar spraying with growth regulators (IAA and GA3 ) showed significant effect on plant, to the extent of reducing the hurt effect of salinity on the vegetative measurements and some physiological components of plant (Gherroucha et al, 2011). Shalaby and Kishk (1986) confirmed the increase of proline accumulation in the presence of growth regulators; stimulating hormones, especially quinine, regulate the synthesis and accumulation of dissolved sugars in growing plants in ss.m ab / prl.e, respectively.…”

The Role of Gibberellic Acid in Alleviating the Adverse Effect of Saline Irrigation Water on Growth and Yield Components of Barley Plant.

“…The spraying of GA 3 , showed a significant effect on plant, in the extent of reducing the hurt effect of salinity on the vegetative measurements and some components of plant (Gherroucha et al, 2011). The application method of GA 3 had a stimulated effect on the adverse effect of salinity stress on the growth parameters and survival percentage for acclimatization stage (Darwesh and Mohamed, 2009).…”
