Gibberellic acid 10% TA

Cov nyhuv ntawm lub cev

Txhawb kev ntev thiab kev loj hlob ntawm cov qia
Qhov cuam tshuam tseem ceeb tshaj plaws ntawm gibberellinic acid (gibberellin) yog txhawb kev loj hlob ntawm cov nroj tsuag, feem ntau vim nws tuaj yeem txhawb kev ntev ntawm cov hlwb. Kev txhawb nqa kev loj hlob ntawm GA muaj cov yam ntxwv hauv qab no:

1. Txhawm rau txhawb kev loj hlob ntawm tag nrho cov nroj tsuag, kev kho mob GA tuaj yeem txhawb kev loj hlob ntawm cov qia ntawm cov nroj tsuag, tshwj xeeb tshaj yog rau cov hom dwarf mutant, raws li pom hauv Daim Duab 7-11. Txawm li cas los xij, GA tsis muaj qhov cuam tshuam loj rau kev ntev ntawm cov qia cais, thaum IAA muaj qhov cuam tshuam loj rau kev ntev ntawm cov qia cais. Qhov laj thawj vim li cas GA txhawb kev ntev ntawm cov nroj tsuag dwarf yog vim tias cov ntsiab lus ntawm GA hauv cov hom dwarf qis dua li ntawm cov hom ib txwm vim yog kev cuam tshuam ntawm endogenous GA synthesis.

2. Txhawb kom internode elongation GA feem ntau ua rau internode elongation uas twb muaj lawm, es tsis yog txhawb kom muaj kev nce ntxiv ntawm cov nodes.

3. Tsis muaj kev cuam tshuam ntawm qhov kev sib xyaw ua ke zoo tshaj plaws Txawm tias qhov kev sib xyaw ua ke ntawm GA siab heev, nws tseem tuaj yeem qhia qhov kev txhawb nqa siab tshaj plaws, uas txawv ntawm qhov xwm txheej uas auxin txhawb nqa kev loj hlob ntawm cov nroj tsuag nrog qhov kev sib xyaw ua ke zoo tshaj plaws.

4. Cov hom nroj tsuag thiab ntau hom teb rau GA txawv heev. Siv GA rau cov zaub (celery, lettuce, leek), nyom, tshuaj yej, ramie thiab lwm yam qoob loo yuav tau txiaj ntsig ntau.

Kev tawg paj ua rau muaj kev cuam tshuam
Qhov sib txawv ntawm cov paj hauv qee cov nroj tsuag siab dua yog cuam tshuam los ntawm lub hnub ntev (photoperiod) thiab qhov kub. Piv txwv li, biennials xav tau ib qho naj npawb ntawm kev kho mob kub qis (piv txwv li, vernalization) kom paj, txwv tsis pub lawv qhia kev loj hlob rosette yam tsis muaj bolting paj. Yog tias GA siv rau cov nroj tsuag tsis muaj vernalized no, paj tuaj yeem tshwm sim yam tsis muaj txheej txheem kub qis, thiab qhov cuam tshuam yog qhov pom tseeb heev. Tsis tas li ntawd, GA kuj tseem tuaj yeem ua rau paj ntawm qee cov nroj tsuag ntev hnub es tsis yog cov nroj tsuag ntev hnub, tab sis GA tsis muaj txiaj ntsig txhawb nqa rau kev sib txawv ntawm cov paj ntawm cov nroj tsuag luv hnub. Piv txwv li, GA tuaj yeem txhawb kev paj ntawm stevia, ntoo hlau thiab cypress thiab fir nroj tsuag.

Tua lub sijhawm pw tsaug zog
Kev kho cov qos yaj ywm uas tsis muaj zog nrog 2 ~ 3μg · g GA tuaj yeem ua rau lawv tawg sai, yog li ua tau raws li qhov xav tau ntawm kev cog qos yaj ywm ntau zaus hauv ib xyoos. Rau cov noob uas xav tau lub teeb thiab qhov kub qis kom tawg, xws li zaub xas lav, luam yeeb, Perilla, txiv plum thiab noob txiv apple, GA tuaj yeem hloov lub teeb thiab qhov kub qis kom tawg dormancy, vim GA tuaj yeem ua rau muaj kev tsim cov α-amylase, protease thiab lwm yam hydrolases, thiab catalyze qhov kev puas tsuaj ntawm cov khoom khaws cia hauv cov noob rau kev loj hlob thiab kev txhim kho ntawm cov menyuam yaus. Hauv kev lag luam tsim npias, kev kho cov noob barley uas tsis muaj germination nrog GA tuaj yeem ua rau muaj α-amylase ntau lawm, ua kom cov txheej txheem saccharification sai dua thaum lub sijhawm ua cawv, thiab txo qhov kev siv pa ntawm germination, yog li txo cov nqi.

Txhawb kom muaj kev sib txawv ntawm cov paj txiv neej
Qhov feem pua ​​ntawm cov paj txiv neej tau nce ntxiv tom qab kho GA rau cov nroj tsuag uas muaj tib tsob nroj. Cov nroj tsuag poj niam dioecious, yog tias kho nrog GA, kuj yuav tsim cov paj txiv neej. Cov nyhuv ntawm GA hauv qhov no yog qhov sib txawv ntawm auxin thiab ethylene.

Cov nyhuv ntawm lub cev

GA kuj tseem tuaj yeem ua kom muaj zog ntawm IAA cov txiaj ntsig ntawm cov as-ham, txhawb kev teeb tsa txiv hmab txiv ntoo thiab parthenocarpy ntawm qee cov nroj tsuag, thiab ncua cov nplooj laus. Tsis tas li ntawd, GA kuj tseem tuaj yeem txhawb kev faib cell thiab kev sib txawv, thiab GA txhawb kev faib cell vim yog qhov luv ntawm G1 thiab S theem. Txawm li cas los xij, GA inhibits kev tsim cov hauv paus adventitial, uas txawv ntawm auxin.

Txoj kev siv

1. Txhawb kom cov txiv hmab txiv ntoo pib loj hlob los yog tsis muaj noob. Tshuaj tsuag 50-100mg/kg kua txiv lws suav ib zaug thaum lub sij hawm paj kom pab kom cov txiv hmab txiv ntoo pib loj hlob thiab nce qoob loo. 7-10 hnub tom qab paj, cov txiv hmab txiv ntoo tsw qab paj yeeb raug tsuag 200-500mg/kg kua txiv lws suav ib zaug kom pab kom cov txiv hmab txiv ntoo tsis muaj pob zeb loj hlob.

2. Txhawb kev loj hlob ntawm cov khoom noj khoom haus ntawm celery 2 lub lis piam ua ntej sau qoob loo, tshuaj tsuag nplooj nrog 50-100mg / kg kua tshuaj ib zaug; Tshuaj tsuag nplooj 1-2 zaug 3 lub lis piam ua ntej sau qoob loo kom nthuav cov qia thiab nplooj.

3. Muab cov noob qos yaj ywm tso rau hauv dej nrog 0.5-1mg/kg kua rau 30 feeb ua ntej tseb cov qos yaj ywm kom tawg kev pw tsaug zog thiab txhawb kev tawg paj; Muab cov noob qos yaj ywm tso rau hauv dej nrog 1mg/kg ntawm cov tshuaj ua kua ua ntej tseb tuaj yeem txhawb kev tawg paj.

4. Tiv thaiv kev laus thiab kev ua kom tshiab Qej moss nrog 50mg / kg tshuaj rau 10-30min, citrus ntsuab txiv hmab txiv ntoo lub sijhawm nrog 5-15mg / kg tshuaj tsuag txiv hmab txiv ntoo ib zaug, txiv tsawb tom qab sau nrog 10mg / kg tshuaj tsuag txiv hmab txiv ntoo, dib, dib liab ua ntej sau nrog 10-50mg / kg tshuaj tsuag melon, tuaj yeem ua si cov nyhuv tshiab.

5. Kho cov paj chrysanthemum vernalization theem nrog 1000mg / kg kua tsuag nplooj, cyclamen bud theem nrog 1-5mg / kg kua tsuag buds tuaj yeem txhawb kev paj.

6. Yuav kom txhim kho qhov ceev ntawm kev tsim cov noob nplej sib xyaw, feem ntau pib ntawm 15% ntawm cov noob niam, thiab kho nrog 25-55mg/kg tshuaj kua rau 1-3 zaug thaum kawg ntawm 25% ntawm cov noob. Siv cov tshuaj tsawg ua ntej, tom qab ntawd siv cov tshuaj ntau.

Cov teeb meem uas xav tau kev saib xyuas

1. Gibberellic acid tsis yaj hauv dej, yaj nrog me ntsis cawv lossis cawv ua ntej siv, thiab tom qab ntawd dilute nrog dej kom txog thaum xav tau.

2. Cov noob qoob loo uas tsis muaj kab mob uas tau kho nrog gibberellic acid tau nce ntxiv, yog li nws tsis tsim nyog siv tshuaj rau hauv cov teb cog qoob loo.
