transgenic and non transgenic nicotiana tabacum l (cultivar wisconsin) containing ri t-dna were treated with 0, 0.2 and 0.4 mgl-1 ga3 in murashig and skoog medium. some physiological parameters including shoot length, leaf area, number of auxiliary bud, fresh and dry weight, number and length of trichomes were measured. shoot length, fresh weight and dry weight were increased but number of tric...

Campanula phitosiana Yıldırım & Şentürk, is a local endemic to the Aydın Mountain range, which distribute across in Western Anatolia (both İzmir and Aydın). This species belongs Mediterranean basin floristic region. According International Union for Conservation of Nature’s criteria, C. classified as “Critically Endangered” (CR). The aim study develop vitro regeneration protocol critica...

the effect of gibberellic acid (ga3) and benzyladenine (ba) on aloe vera was evaluated at pot cultivation conditions. this study was performed in two factorial test based on complete random plan and 4 repeats with 12 treatments. the main factor was included spraying, drip and spraying + drip. secondary factor was included concentrations of ga3 and ba at 0, 100, 200 and 400 mg.l-1 levels. the nu...

Neem is a highly heterozygous and commercially important perennial plant. Conventionally, it is propagated by seeds which loose viability within two weeks. Strictly cross pollinating nature of the plant causes serious barrier to the genetic improvement by conventional methods. Alternative methods of tree improvement such as somatic hybridization, mutagenesis and genetic transformation require a...

Background: Monovarietal cultivation of cotton plant allowed the genetic erosion for traditional varieties that proceed essential traits mainly involved in breeding. These need to be preserved future used. This study aims evaluate effect gibberellic acid on seed germination and Benzylaminopurin (BAP), Kinetin (KIN), α-naphthalene acetic (NAA) activated charcoal (CA) seedlings growth obtained fr...

This study was conducted to assess the influence of gibberellic acid (GA3) and arbuscular mycorrhizal fungi (AMF) on flowering quality Zantedeschia albomaculata (Hook.) Baill ‘Albomaculata’ plants. Before planting, rhizomes were soaked in water or an aqueous solution GA3 at a concentration 150 mg dm−3 for 30 min. A mixture AMF applied week after planting. The treatment increased yield infloresc...

abstract this research was conducted to evaluate the effect of gibberellic acid (ga3) (0.250, 500 and750 mg l-1) on vegetative growth of olive sapling (olea europaea l) in 2004-05 at shahid chamran university of ahvaz. the experiment was a completely randomize design with 4 replications. parameters measured were: shoot height, inter-node length, leaf and root area, fresh and dry weight of shoot...

this study was conducted to identify the effect of gibberellic acid (ga3) on morphological characteristics of pistachio fruits. the following parameters were evaluated; unfilled fruiting, the fruit fraction, bearing and yield. this research was carried out from 2007 till 2010 in a split plot design with five concentrations of ga3 (0, 2500, 5000, 10000 and 20000 mg/l) in four replications. the m...

Gibberellins act to overcome dormancy and increase the germination rate of seeds several species, including genus Annona. Considering that Annona have a high lipid content few sugars, degradation such reserves from application gibberellins has not been described so far. This study aimed evaluate how different gibberellic acid (GA3) concentrations acts on sugar pattern during atemoya (Annona x M...

Polyamines (PAs) are involved in various developmental processes, especially plant flowering. Their significant influences have been established; however, the exact mechanism by which PAs regulate flowering remains unclear. To explore PA metabolism flowering, gibberellic acid (GA3, 0~2400 mg L?1) and spermidine (Spd, 0~1 mM) were applied alone or combination during early stage of flower bud for...
