field trials with dizigotheeca elegantissima were conducted at the experimental farm of faculty of agriculture, azad university  jiroft  in growth seasons of 2012 year. the aim of this work was to study the effect of foliar application of gibberellic acid [ga3] and benzyladenine [ba] at 0, 50, 100 and 150 mgl-1 on the vegetative growth and photosynthetic pigments of d. elegantissima plants. mos...

Seed priming improves vigor, but priming agents may differ greatly in their effectiveness. The present study was performed to unravel the physiological basis of vigor improvement by priming sunflower achenes with pre-optimized levels of hydrogen peroxide (H2O2), salicylic acid (SA), thiourea (TU), gibberellic acid (GA3), ascorbic acid (AA), sodium chloride (NaCl), freezing and heating. Most of ...

Many changes in development, growth, hormone activity and environmental stimuli responses are mediated by mitogen-activated protein kinase (MAPK) cascades. However, in plants, studies on MAPKs have mainly focused on MPK3, MPK4 and MPK6. Here, a novel group B MAPK gene, GhMPK11, was isolated from cotton (Gossypium hirsutum L.) and characterized. Both promoter and expression pattern analyses reve...

Beneficial effects in bone cell growth and antibacterial action are currently attributed to Ga3+ ions. Thus, they can be used to upgrade mesoporous bioactive glasses (MBGs), investigated for tissue engineering, whenever they released therapeutic amounts of gallium ions to the surrounding medium. Three gallium-enriched MBGs with composition (in mol %) xSiO₂-yCaO-zP₂O₅-5Ga₂O₃, being x = 70, y = 1...

The genetic control of dormancy is poorly understood in most plant species, but dormancy is a prominent feature for the potato industry. We used the microtuber system, in which tubers were produced in vitro and stored at 20°C, to perform quantitative trait locus (QTL) analysis for dormancy and gibberellic acid (GA3) content in an F1 population consisting of 178 genotypes derived from an intersp...

The accumulation of a considerable quantity of gibberellin fermentation residue (GFR) during gibberellic acid A3 (GA3) production not only results in the waste of many resources, but also poses a potential hazard to the environment, indicating that the safe treatment of GFR has become an urgent issue for GA3 industry. The key to recycle GFR is converting it into an available resource and removi...

Effect of sodium arsenate (Na2HAsO4.7H2O) on the growth and activity of few oxidizing enzymes of mungbean seedlings was investigated and it was found to have drastic effects on the growth and biochemical metabolism of germinating mungbean (Vigna radiata (L.) Wilczek cv. B-105) seedlings. With the increase in concentration of sodium arsenate (5μM, 10μM and 20μM) significant decrease in seedling ...

The aim of this study was the better assessment of the relationship of pulsing treatment of gibberellic acid as an anti-senescence agent and holding in sucrose as a carbohydrate supply resource on improving some qualitative and physiological attributes of cut rose flower cv. Velvet. Hence, an experiment involving the pulsing treatment with gibberllic acid (GA3) at 0, 20, 40 and 60 mg L-1, for 2...

This paper presents a new bi-level formulation for time-varying lane-based capacity reversibility problem for traffic management. The problem is formulated as a bi-level program where the lower level is the cell-transmission-based user-optimal dynamic-traffic-assignment (UODTA) linear program. Due to its NP-hard complexity, the genetic algorithm (GA) with the simulationbased UODTA is adopted to...

The purpose of this study was to determine the effects different doses gibberellic acid (GA3) on growth, tuber yield and some quality traits potato. experiment arranged in a split-plot design with three replicates, cultivars Marabel, Alegria Agria were main plots, GA3 (0, 25, 50 100 mg L-1) sub-plots. Gibberellic applied leaves by spraying 50th day after planting (during flowering). application...
