the effects of the plant growth promoter gibberellic acid (ga3) and plant growth retardant chlormequat chloride (ccc) on biomass and quality of angelica dahurica var.formosana plants were investigated employing physiological and biochemical methods. plants were sprayed with ga3 or ccc at rosette stage and coumarin content was analyzed by high performance liquid chromatography (hplc) after harve...

abstract the present research was conducted in a commercial orchard of pistachio during 2006-2007 in rafsanjan, iran. gibberellic acid (ga3) were applied at 0, 25, 50 and 75 mgl-1 and at three time of spray (the first of june, july and august) on “ahmad-aghai” pistachio cultivar. two branches of each tree was sprayed during two years of study. spraying at june had least of early splitting. ga3 ...

Induction of sprouting is widely used in Solanum tuberosum tubers to reduce the sprout growth time. The main objective this article was evaluate effect different concentrations gibberellic acid (GA3), ethanol, and hydrogen cyanamide (Dormex) on budding buds, length, number sprouts L. var. Cecilia tubers. Previously disinfected were immersed three inducers at placed two peat-based substrates (TS...

BACKGROUND The phytohormone gibberellic acid (GA3) is widely used in the table grape industry to induce seedlessness in seeded varieties. However, there is a paucity of information concerning the mechanisms by which GAs induce seedlessness in grapes. METHODOLOGY/PRINCIPAL FINDINGS In an effort to systematically analyze the cause of this GA3-induced seed abortion, we conducted an in depth char...

in order to investigate factors affecting on seed germinating of london rocket (sisymbrium irio), lab experiments were set up in 2011 at the payamenoor university, mashhad, khorasan razavi province. effect of different concentrations of gibberellic acid (ga3) and cytokinin, wet and dry prechilling duration, hydrogen peroxide duration, ethanol, salt and osmotic stress and burial depth on seed ge...

Chloroplast Envelope, Permeability Coefficients, Phytohormones, Plasmalemma, Spinach The uptake of auxin (LAA), abscisic acid (ABA) the synthetic cytokinin benzylaminopurine (BA), gibberellic acid (GA3) and mevalonic acid (lactone) (MVA) into intact chloroplasts and protoplasts from spinach mesophyll cells was measured and the permeability coefficients Ps of the chloroplast envelope and the pla...

Plant hormone keeps a significant role to enlarge the fruit size and quality development. Fruit growers have a lot of interest in making fruit enlargement and shorten maturity to harvest fruit earlier and to make it marketable soon. Gibberellic Acid (GA3) and bark stress play a significant role in fruit enlargement and development. Bilimbi fruit was used in this experiment. The flower bud were ...

The aim of this work was to evaluate phytohormone biosynthesis, siderophores production, and phosphate solubilization in three strains (E109, USDA110, and SEMIA5080) of Bradyrhizobium japonicum, most commonly used for inoculation of soybean and nonlegumes in USA, Canada, and South America. Siderophore production and phosphate solubilization were evaluated in selective culture conditions, which ...

Noni juice processing industry depends explicitly on the quality of noni fruits and its together with increased production fruits. This study evaluated effects chemical treatments noni's fruiting capacity, fruit yield antioxidant properties. plants in stage were foliar fed boric acid (BA) at a concentration 100 ppm or 200 ppm, gibberellic (GA3) 20 40 sucrose solution 5 20% water (control).
