Phytohormones are present in seaweeds but little is known about occurrence and content of them in seaweeds of Persian Gulf. The aim of this study was extraction of abscisic acid and gibberellin in Sargassum muticum and Gracilaria corticata. The seaweeds were collected bimonthly over one year at Bushehr coasts, Persian Gulf, during a range of environmental conditions. We explored new HPLC method...

Establishment of an efficient and reproducible regeneration protocol is one of the basic prerequisites for genetic transformation of any crop plant. In vitro culture of lentil has proven to be difficult. In spite of a number of reports on the regeneration of this plant, very few satisfying and reproducible protocol has yet been reported. This study carried out for investigation of diff...

Abstract Flowers are key organs in many ornamental plants, and various phases of flower development impact their economic value. The final stage petal is associated with senescence, which an irreversible process involving programmed cell death, premature senescence cut flowers often results major losses quality during postharvest handling. Flower opening two sequential processes. As open, the s...

Phytohormones, their functions, synthesis and effects, are of great interest. To study them in plant tissues accurate and sensitive methods are required. In the present study we aimed at optimizing experimental conditions to separate and determine not only plant hormones but also their metabolites, by liquid chromatography coupled with a UV-VIS detector. The mixture we analyzed was composed of ...

Phytohormones (PHs) play crucial role in regulation of various physiological and biochemical processes that govern plant growth yield under optimal stress conditions. The interaction these PHs is for survival stressful environments as they trigger signaling pathways. Hormonal cross initiate a cascade reactions which finely tune the architecture help to grow suboptimal Recently, studies have hig...

Microalgae possess similar characteristics to higher plants and research has shown that phytohormones can influence the metabolic physiological properties of microalgae. Trace amounts affect production performance microalgae, which be used increase yield specific components elevate position microalgae in industrial raw material supply chain, promote green production, reduce carbon emissions. Th...
