Cog Kev Loj Hlob Regulator Gibberellin Ga3 90% Tc
Gibberellin (GA) yog ib qho tseem ceebcog kev loj hlob regulatornyob rau hauv lub neej niaj hnub no.Muaj ntau hom gibberellins, uas feem ntau siv rau hauv kev ua liaj ua teb thiab ua lub luag haujlwm hauv cov noob germination, nplooj extension, qia thiab hauv paus elongation, thiab paj thiab txiv hmab txiv ntoo.Lub luag haujlwm tseem ceeb ntawm kev tswj hwm, dav siv hauv kev tswj hwm txhua hnub ntawm cov qoob loo.
Lub luag haujlwm ntawm gibberellin
Lub luag haujlwm tseem ceeb ntawm gibberellin yog txhawm rau txhawm rau elongation ntawm cov hlwb (gibberellin tuaj yeem ua kom cov ntsiab lus ntawm auxin hauv cov nroj tsuag, thiab auxin ncaj qha tswj cov elongation ntawm cov hlwb), thiab nws kuj txhawb kev faib cell, uas tuaj yeem txhawb kev nthuav dav ntawm tes.(tab sis tsis ua rau acidification ntawm phab ntsa ntawm tes), ntxiv rau,gibberellin uakuj muaj physiological teebmeem ntawm inhibiting maturation, lateral bud dormancy, senescence, thiab tuber tsim.Txhawb kev hloov pauv ntawm maltose (induce tsim α? amylase);txhawb kev loj hlob ntawm cov nroj tsuag (tsis cuam tshuam rau hauv paus kev loj hlob, tab sis tseem txhawb kev loj hlob ntawm stems thiab nplooj), tiv thaiv lub cev los ntawm lub cev thiab tawg dormancy, thiab lwm yam.
Yuav siv gibberellin li cas
1. Cov khoom no tuaj yeem sib xyaw nrog cov tshuaj tua kab dav dav thiab tuaj yeem sib koom ua ke.Yog tias siv gibberellin ntau dhau, cov kev mob tshwm sim tuaj yeem ua rau muaj chaw nyob, yog li nws feem ntau tswj hwm los ntawm metrophin.Lus Cim: Tsis tuaj yeem sib xyaw nrog cov tshuaj alkaline, tab sis tuaj yeem tov nrog acidic, nruab nrab chiv thiab tshuaj tua kab, thiab tov nrog urea kom ntau lawm.
2. Lub sij hawm txau yog ua ntej 10:00 sawv ntxov thiab tom qab 3:00 tav su, yog tias nws los nag hauv 4 teev tom qab tshuaj tsuag, nws yuav tsum tau muab tshuaj tsuag dua.
3. Lub concentration ntawm cov khoom no yog siab, thov npaj raws li qhov ntau npaum.Yog tias qhov concentration siab dhau lawm, leggy, whitening yuav tshwm sim kom txog thaum deformed los yog withered, thiab cov nyhuv tsis pom tseeb yog tias qhov concentration tsawg dhau.Tus nqi ntawm cov kua siv rau nplooj zaub txawv nrog qhov loj thiab ntom ntawm cov qoob loo.Feem ntau, tus nqi ntawm cov kua siv ib mu tsis tsawg tshaj li 50 kg.
4. Cov tshuaj aqueous ntawm gibberellin yog ib qho yooj yim rau decompose thiab yuav tsum tsis txhob khaws cia rau lub sijhawm ntev.
5. Kev siv ntawmgibberellin uatsuas tuaj yeem ua lub luag haujlwm zoo nyob rau hauv cov xwm txheej ntawm cov chiv thiab dej, thiab tsis tuaj yeem hloov cov chiv.
