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...

The effect of plant growth hormones (kinetin, gibberellic acid (GA3) and indole acetic acid (IAA)) on EMS-induced mutant wing spots was studied with the somatic mutation and recombination test (SMART) in Drosophila melanogaster. GA3 reduced all kinds of EMS-induced spot. While a 10 -3 M concentration of kinetin reduced only the number of EMS-induced twin spots, a 10-4 M concentration was seen t...

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 ...

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 ...

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...

leaf yellowing is a major problem in postharvest of alstroemeria cut flowers. for delaying of leaf yellowing and increasing flower quality a completely randomized factorial design was carried out on the alstroemeria cut flowers (‘fuji’ cultivar). in this research ethanol (0, 2, 4, 6%), ga3 (0, 50, 100, 150 mg/litre) in two methods (pulse and continuous) were investigated on the flower vese life...

Abstract. Dwiati M, Widodo P, Susanto AH. 2023. Shoot regeneration in Nepenthes mirabilis as affected by flurprimidol and GA3 application. Biodiversitas 24: 4168-4174. (Lour.) Druce. is a pitcher plant species at higher risk of extinction mainly due to overexploitation. Previous investigations have shown that vitro micropropagation can be used an approach for ex-situ conservation N. mirabilis. ...

Rhodothamnus sessilifolius is a species of the Ericaceae family endemic to Artvin province in NE Turkey. This critically endangered list and current populations are decreasing, therefore, it requires protection reproduction. Thus present study aimed investigate effect various gibberellic acid (GA3) applications on germination R. seeds. The effects GA3 concentrations final percentage, mean time,...

Objective: In order to investigate effects of different concentration of gibberlic acid and poly amines on germination and early growth of Pishtaz cultivar under salinity stress. Methods: The experiment was carried out as factorial based on completely randomized design with four replicates in laboratory of agronomy and plant breeding of agricultural department, Islamic Azad University, Varamin-...

Eastern black walnut (Juglans nigra L.) is used as a rootstock for the Persian walnut (Juglans regia L.) in some parts of the world and also has an important role in forestry and wood industry. Due to the deep physiological dormancy, the seed often shows an inconsistent or low germination percentage, making establishment difficult. This experiment was carried out as a completely randomized desi...
