Gibberellin muaj kev cuam tshuam ntawm kev txhawb nqa tsob ntoo germination, ceg thiab cov nplooj av loj hlob, thiab tawg paj thaum ntxov. Nws muaj cov txiaj ntsig tseem ceeb nce ntxiv rau cov qoob loo xws li cov paj rwb, taum pauv, cov qoob loo, cov txiv hmab txiv ntoo cog qoob loo, thiab ntoo txiv ntoo, thiab ntoo txia.
Taw qhia rau gibatellic acid
Giberellic acid, tseem hu ua Gibberellin, hais txog chav kawm ntawm cov tebchaw nrog gibberellin pob txha thiab elongation. Nws yog ib qho ntawm cov regulators nrog cov kev cai tswj cov nyhuv tseem ceeb thiab qhov dav tshaj plaws ntawm kev siv tam sim no.
Cov nyhuv ntawm giberellic acid:
Kev ua kom pom tseeb tshaj plaws ntawm roj ntsha ntawm gibbertellic acid yog los txhawb cov nroj tsuag cell elongation, uas yog cog kev loj hlob thiab nplooj hlav;
Tuaj yeem tsoo cov dormancy ntawm cov noob, tubers, thiab cov hauv paus tubers, txhawb lawv cov germination;
Tuaj yeem txhawb cov txiv hmab txiv txiv kev loj hlob, ua rau cov noob teeb tsa lossis cov txiv hmab txiv ntoo wedless;
Nws tuaj yeem hloov ntsuas kub tsawg dua thiab txhawb nqa cov paj thaum ntxov ua kom sib txawv hauv cov nroj tsuag uas yuav tsum tau qhov kub tsawg kom dhau los ntawm theem kev loj hlob;
Nws tseem tuaj yeem hloov cov nyhuv ntawm lub hnub ci ntev, tso cai rau qee cov nroj tsuag rau kev tawm thiab tawg txawm nyob hauv qab hnub ci ntsa iab;
Yuav tsis ntxias α- amylase tsim nrawm lub hydrolysis ntawm cov tshuaj khaws cia hauv endosperm hlwb.
Daim ntawv thov tshuab ntawm giberellic acid
1, gibberellin so noob dormancy
Zaub pob: Zaub xas lav noob tuaj yeem soaked nyob rau hauv ib 200mg / l concentration ntawm gibberellin daws ntawm qhov kub ntawm 30-38 ℃ rau 24 teev kom ua tiav dormancy thiab sprout thaum ntxov.
Qos yaj ywm: So cov qos yaj ywm hauv gibberellin daws nrog lub tswv yim ntawm 0.5-2Mg / u rau lub ntsej muag ntawm 5-15 mg / l rau 30 feeb. Qhov no tuaj yeem daws lub dormancy lub sij hawm ntawm qos tubers, txhawb nqa thaum ntxov, thiab txhawb nqa tom qab sprouting. Kev loj hlob ntawm cov tub ntxhais hluas tawm kom nrawm, thiab cov ceg caws pliav tshwm sim thaum ntxov, txuas ntxiv rau lub caij o, thiab tuaj yeem nce tawm los ntawm 15-30%. Ntau yam nrog luv luv dormancs lub sijhawm siv qis dua, thaum cov uas muaj lub sijhawm dormancy ntev siv ntau dua cov kev xav.
Txiv av: Txau lub tswv yim ntawm 2000-4000mg / l gibberellin tov nyob rau hauv thaum ntxov caij nplooj ntoos hlav tuaj yeem tsoo cov dormancy ntawm Kua buds thiab muaj cov nyhuv tseem ceeb.
Golden Lotus:Soaking cov noob nyob rau hauv 100mg / l concentration ntawm gibberellin daws ntawm chav tsev kub rau 3-4 hnub tuaj yeem txhawb kev germination.
Strawberry:Nws tuaj yeem tsoo cov dormancy ntawm cov nroj tsuag Strawberry. Nyob rau hauv strawberry tsev cog khoom pab kev cog qoob loo thiab semi pab kev sau qoob, nws yog nqa tawm tom qab 3 hnub ntawm tsev cog khoom rwb thaiv tsev, thaum lub paj tawg ntau dua 30%. Txhua tsob nroj tsuag tsuag nrog 5ml ntawm 5-10mg / l concentration ntawm gibberellin daws, uas tuaj yeem ua rau lub siab sab saum toj nplooj, uas tuaj yeem txhawb kev loj hlob, txhawb kev loj hlob, thiab paub tab ua ntej.
2, Gibberellin tiv thaiv cov paj, txiv hmab txiv ntoo, thiab txhawb kev loj hlob
Eggard: Txau gibberellin daws ntawm lub siab ntawm 25-35mg / u ib zaug thaum lub sij hawm paj tuaj yeem tiv thaiv cov paj poob, txhawb cov txiv ntoo, thiab nce tawm los.
Txiv lws suav: Txau gibberellin daws ntawm lub siab ntawm 30-35 mg / u ib zaug thaum lub sij hawm ua paj tau nce cov txiv hmab txiv ntoo thiab tiv thaiv cov txiv ntoo hollow.
Kiwifruit:Thov 2% Gibberellin Lanolin ntawm cov paj stalks tuaj yeem txo tus naj npawb hauv kiwifruit, thiab txo tus nqi ntawm cov txiv hmab txiv ntoo abscission.
Kua Chili Kua Muag:Txau gibberellin daws ntawm ib co siab ntawm 20-40mg / u ib zaug thaum lub sijhawm ua paj tuaj yeem txhawb cov txiv hmab txiv ntoo thiab nce tawm los.
Lub dib liab,Lub caij ntuj no, taub dag, dib: Txau gibberellin daws ntawm lub siab ntawm 20-50mg / l ib zaug thaum lub sij hawm flowering lossis ib zaug during hluas melon kev loj hlob tuaj yeem txhawb txoj kev loj hlobThiab cov lus cog tseg ntawm Melon.
Ceev faj rau kev siv:
1. Gibbertellic acid muaj tsawg solubility. Ua ntej siv, yaj nws nrog me ntsis ntawm dej cawv los yog baijiu, thiab tom qab ntawd ntxiv dej kom dilute.
2. Kev siv ntawm gibatellic acid kho nce tus naj npawb ntawm cov noob muaj peev xwm hauv cov qoob loo, yog li nws tsis yog xav tau siv tshuaj tua kab hauv lub teb.
