Daim ntawv thov
1.Gibberellin A4 + A7 yog ib qho kev faib ua feem sib xyaw ntawm cov nroj tsuag kev loj hlob, feem ntau yog siv los txhawb kev teeb tsa txiv hmab txiv ntoo thiab txhim kho cov txiv hmab txiv ntoo. Nws yog tshwj xeeb tshaj yog zoo rau txiv apples thiab pear ntoo.
Gibberellin tsis yog ib yam khoom, tab sis ib lo lus dav dav rau ib pawg loj ntawm cov tshuaj hormones cog. Tam sim no, muaj ntau tshaj li ib puas yam paub. Lawv muaj dav nyob rau hauv cov nroj tsuag thiab tswj ntau yam physiological txheej txheem ntawm cov nroj tsuag, xws li:
Txhawb nqa qia elongation, tawg lub dormancy ntawm cov noob thiab buds, induce flowering, thiab cuam tshuam cov txiv hmab txiv ntoo thiab kev loj hlob ntawm txiv hmab txiv ntoo.
Hauv kev ua liaj ua teb, cov hom gibberellins uas peb nquag siv yog cov uas tau muab rho tawm los ntawm microbial fermentation thiab muaj kev ua haujlwm siab tshaj plaws. Ntawm lawv, qhov zoo tshaj plaws -paub yog GA3 (Gibberellin A3).
2. "A4 + A7" tshwj xeeb yog hais txog ob hom gibberellins.
Lawv feem ntau tsim thiab purified ua ke, sib sau ua ke.
Qhov sib xyaw no (GA4 + GA7) qhia tau hais tias muaj txiaj ntsig zoo dua li GA3 ib leeg hauv kev txhawb nqa cov txiv hmab txiv ntoo thiab kev txhim kho txiv hmab txiv ntoo rau qee cov qoob loo (tshwj xeeb yog cov hauv tsev neeg Rosaceae), thiab qee zaum muaj kev phiv tsawg dua.
Main Functions thiab Applications
Lub luag haujlwm tseem ceeb ntawm GA4+A7 yog los hloov lossis txhim kho cov tshuaj hormones endogenous, yog li tswj kev loj hlob thiab kev loj hlob. Nws cov kev siv tseem ceeb yog:
Mechanism: Thaum txau thaum lub sij hawm tawg paj los yog thaum cov txiv hmab txiv ntoo tseem hluas, nws tuaj yeem ua rau lub zes qe menyuam loj, ua rau cov txiv hmab txiv ntoo tsis muaj noob thiab tiv thaiv cov txiv hmab txiv ntoo poob los ntawm kev tsis zoo pollination lossis ib puag ncig kev ntxhov siab (xws li kub tsis tshua muaj).
Kev siv cov qoob loo: txiv apples, pears, plums, cherries, thiab lwm yam.
Mechanism: GA4 + A7 tuaj yeem txhawb nqa kev faib tawm ntawm tes thiab elongation ntawm lub paj calyx kawg, ua rau cov txiv hmab txiv ntoo siab dua thiab nrog cov duab zoo nkauj pentagonal. Cov txiv hmab txiv ntoo zoo li no nrov dua hauv kev ua lag luam.
Daim ntawv thov cov qoob loo: Apples (tshwj xeeb tshaj yog rau ntau yam nrog cov txiv hmab txiv ntoo tshwj xeeb).
Nco tseg: Txhawm rau ua tiav cov txiaj ntsig zoo tshaj plaws ntawm kev txhim kho cov txiv hmab txiv ntoo, GA4 + A7 feem ntau yog tov nrog lwm cov nroj tsuag kev loj hlob, 6-BA (benzylaminopurine), thiab cov khoom uas muaj "Promomalin" yog cov khoom sib xyaw ntawm GA4 + GA7 thiab 6-BA.
Ntawm cov txiv hmab txiv ntoo, qee zaum nws yog siv los elongate bunches.
Ntawm paj, nws tuaj yeem txhawb nqa paj thiab tswj lub sijhawm paj.
Cim npe nrov: Gibberellin nyob rau hauv cov nroj tsuag, Tuam Tshoj gibberellin nyob rau hauv cov nroj tsuag manufacturers, lwm tus neeg, hoobkas
