Interactions affecting gibberellic acid
The production of GA3 in solid-state culture was studied using systems composed of maize cob particles soaked in an amylaceous efluent, as a function of three variablesparticle diameter, volume of liquid phase, and substrate concentration-with a determinant influence on the response. The empirical model obtained provides an explanation of the behavior of the system in terms of a series of inter...
متن کاملstudy of dna interaction with ethylenediaminetetraacetic acid and sesamol food additives
برهمکنش dnaتیموس گاوی طبیعی (ct-dna) با اتیلن دی آمین تترااستات (edta)در بافرtris-hcl با 8/7 ph ( دراین ph،edta به نمک دی سدیم تبدیل می شود) وسسامول در بافر tris-hcl با4/7 ph مورد بررسی قرار گرفته است. edta و سسامول استفاده فراوانی در تکنولوژی غذایی و صنعت شیمیایی دارند. مدل اتصال dna مربوط بهedta بوسیله اسپکتروفتومتری جذب، دورنگ نمایی حلقوی(cd)، ویسکومتری وژل الکتروفورز بررسی شده است. طیفuv ...
15 صفحه اولProduction of gibberellic acid by fermentation.
The elonigationi of rice plants iinduced by the application of cell-free culture filtrates from the li(uid culture of Futsariutm moniliforme was first demonstrated in 1926 by Kurosawa. Twelve years later, Yabuta and Sumiki (1938) were able to isolate in crystalline form two growth-promotinig compounds, gibberellins A and B, from filtrates of this organism; gibberellin A was the maini substaniee...
متن کاملAction of Gibberellic Acid in Rice Seed
To evaluate the effectiveness of gibberellic acid (GA 3 ) in breaking rice seed dormancy and the use of a-amylase enzyme activity as an indicator of the dormancy level, seed from the intensively dormant irrigated cultivar Urucuia were used. The seeds were submitted to a predrying process in a forced air circulation chamber under 40oC during 7 days and submersed in 30 mL of GA 3 solution under 0...
متن کاملShape Selective Alkylation of Biphenyl with 1-octene on ((Al+C3H7Cl)+C2H4) Catalysts
Alkylation of biphenyl with 1-octene was investigated using ((Al+C3H7Cl)+C2H4) catalysts. The catalytic activity of ((Al+C3H7Cl)+C2H4) for the alkylation was studied at different temperatures, mol ratios of biphenyl to 1-octene, reaction times and catalyst concentrations. It was shown that using this catalyst has more advantagous than another catalysts. Experiments show that by increasing t...
