Gibberellic Acid GA3: Txhim Kho Kev Loj Hlob, Elongation & Fruit Development

Gibberellic Acid (GA3) - Txhawb Kev Loj Hlob, Elongation & Fruit Development

Gibberellic Acid (GA3) yog ib qho tseem ceeb ntawm cov tshuaj hormones, muaj npe nrov rau nws lub luag haujlwm tseem ceeb hauv kev tswj cov txheej txheem tseem ceeb ntawm kev loj hlob thiab kev loj hlob. Raws li kev siv ntau tshaj plaws ntawm gibberellins, GA3 yog ib qho tseem ceeb rau kev ua liaj ua teb niaj hnub, horticulture, thiab cog biotechnology. Cov khoom no muaj qhov siab -purity formulation, ua kom ntseeg tau thiab rov tsim tau cov txiaj ntsig rau ob qho tib si kev lag luam thiab kev tshawb fawb tshawb fawb.

Physical & Chemical Properties

Chemical Formula: C₁₉H₂₂O₆

Molecular Luj:346,38 g / mol

CAS Nr.: 77-06-5

Qhov tsos:Dawb rau tawm -dawb crystalline hmoov.

Purity:Ntau dua lossis sib npaug li 90% (los ntawm HPLC, qib siab dua muaj nyob rau ntawm qhov kev thov).

Solubility:Soluble hauv ethanol, methanol, acetone, thiab sodium hydroxide daws. Sparingly soluble hauv dej. Nws raug nquahu kom ua ntej yaj hauv ib qho me me ntawm cawv lossis tshuaj alkaline ua ntej diluting nrog dej.

Cov ntawv thov tseem ceeb & siv

Seed Germination & Dormancy Breaking:Txhawb nqa kev loj hlob sai thiab zoo ib yam ntawm cov noob, tshwj xeeb tshaj yog cov uas muaj cov tsho tawv tawv los yog xav tau stratification (xws li, cov noob ntoo, qee cov cereals).

Qeb & Cell Elongation:Stimulates internode elongation nyob rau hauv cov qoob loo xws li txiv hmab txiv ntoo (rau ntev rachises), qab zib, thiab ornamentals, ua rau kom kev loj hlob thiab harvestability.

Fruit Setting & Development:Txhim khu cov txiv hmab txiv ntoo nyob rau hauv tej yam kev mob tsis zoo rau pollination (xws li, nyob rau hauv txiv lws suav, cherries). Nws tuaj yeem siv los ua kom cov txiv ntoo loj hauv cov txiv hmab txiv ntoo thiab txhawb nqa parthenocarpic (seedless) txiv hmab txiv ntoo txoj kev loj hlob.

Paj Induction:Muaj peev xwm hloov lub sij hawm flowering thiab kev sib deev qhia nyob rau hauv ib co nroj tsuag hom (xws li, induce flowering nyob rau hauv ntev -hnub nroj tsuag nyob rau hauv luv luv- hnub tej yam kev mob).

Malting hauv Brewing:Accelerates thiab synchronizes cov txheej txheem malting hauv barley rau kev lag luam brewing.

Cog daim ntaub Culture:Siv nyob rau hauv xov xwm formulations los txhawb kev loj hlob callus, organogenesis, thiab embryo txoj kev loj hlob.
