The effects of gibberellic acid (GA3) on growth, physiology and yield of salt-stressed mustard (Brassica juncea L. Czern & Coss) cv. Varuna plants were studied. The stress imposed by 25 or 50 mM NaCl reduced substantially leaf area, dry mass, leaf chlorophyll content, stomatal conductance and net photosynthetic rate 50 days after emergence. At harvest, although other yield components were gener...

Kaurenoic and grandiflorenic acid, isolated from Wedelia paludosa (Asteraceae), some derivatives from these acids (alcohols, esters, amides, lactones, oximes) and other naturally occurring kaurane diterpenes were tested for their action on the growth of radical and shoot of Lactuca sativa. Gibberellic acid, GA3, a commercially available phytohormone, belonging to the same class of diterpenes, w...

Cycad is one of the most important cut foliage plants with several usages. This experiment was focused on increasing the vase life of Cycad’s cut foliage in normal storage condition. Experiment was based on a CRD with three replications. Treatments were conducted for four different levels of gibberellic acid (GA3) and benzyl adenine (BA) each one with 0, 50, 100 and 150 mg L-1, according to men...

Limes (Citrus aurantifolia Swingle) have a short postharvest life. Therefore, effective treatments increasing storage life to lengthen the time that produce remains fresh is desirable. This study evaluated effects of 1-methylcyclopropene (1-MCP), gibberellic acid (GA3), and Aloe vera on lime fruit quality. The optimum individual 50% coating, 300 mL·L−1 GA3, 750 nL·L−1 1-MCP were identified as m...

Araştırmada kullanılan Tunceli sarımsağı (Allium Tuncelianum) tohumları, 2020 yılı ağustos ayında Isparta Uygulamalı Bilimler Üniversitesi Ziraat Fakültesi deneme bahçesinden temin edilmiştir. Bu çalışmada tohumlarının in vitro koşullarda çimlenmesi ve çoğaltılması üzerine GA3 uygulamalarının etkilerinin belirlenmesi amaçlanmıştır. sterilizasyonu amacıyla 4 faklı sodyum hipoklorit dozu denenmiş...

Micellar electrokinetic chromatography (MEKC) was developed as a method for quantitative determination of gibberellic acid (GA3) in fermentation broth and commercial products, using 25 mM disodium tetraborate as a buffer at pH 9.2 and 100 mM sodium dodecyl sulfate as a micellar phase. The baseline resolution (Rs of GA3 from other compounds in fermentation broth was achieved with Rs > 2.5. The a...

Plant growth studies involve seed germination studies and this depends on storage viability and dormancy aspects besides essential requirements and factors for the same. Of the various factors regulations plant growth and developmental processes intrinsic factors play a significant role. Plant hormones are chemicals that regulate plant growth. These occur in extremely low concentrations and inf...

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...

Rhizome growth and development is regulated by phytohormone. However, endogenous phytohormones affect rhizome initiation, sustained in perennial grass species remains elusive. In this study, we investigated the morphological characteristics content of indole-3-acetic acid (IAA), zeatin (ZT), gibberellic (GA3), abscisic (ABA) rhizomes two different Kentucky bluegrass. Using ultra-performance liq...
