Kev Loj Hlob ntawm Cov Nroj Tsuag Gibberellin Ga3 90% Tc

Gibberellin (GA) yog ib qho tseem ceebkev tswj kev loj hlob ntawm cov nroj tsuagnyob 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 kev tawg noob, kev nthuav nplooj, kev nthuav qia thiab cov hauv paus hniav, thiab kev loj hlob ntawm paj thiab txiv hmab txiv ntoo. Lub luag haujlwm tseem ceeb hauv kev tswj hwm, siv dav hauv kev tswj hwm cov qoob loo txhua hnub.

Lub luag haujlwm ntawm gibberellin
Lub luag haujlwm tseem ceeb ntawm gibberellin yog kom ua kom cov cell ntev dua (gibberellin tuaj yeem ua rau cov auxin ntau ntxiv hauv cov nroj tsuag, thiab auxin ncaj qha tswj hwm qhov ntev ntawm cov cell), thiab nws kuj txhawb nqa kev faib cell, uas tuaj yeem txhawb nqa kev nthuav dav cell. (tab sis tsis ua rau acidification ntawm phab ntsa cell), ntxiv rau,gibberellinkuj muaj cov teebmeem ntawm kev ua haujlwm ntawm kev tiv thaiv kev loj hlob, kev pw tsaug zog ntawm cov paj, kev laus, thiab kev tsim tuber. Txhawb kev hloov pauv ntawm maltose (ua rau muaj α? amylase); txhawb kev loj hlob ntawm cov nroj tsuag (tsis muaj kev cuam tshuam rau kev loj hlob ntawm cov hauv paus hniav, tab sis txhawb kev loj hlob ntawm cov qia thiab nplooj), tiv thaiv kev poob ntawm cov noob thiab tawg kev pw tsaug zog, thiab lwm yam.

Yuav siv cov gibberellin li cas
1. Cov khoom no tuaj yeem sib xyaw nrog cov tshuaj tua kab dav dav thiab tuaj yeem ua ke nrog ib leeg. Yog tias siv gibberellin ntau dhau, cov kev mob tshwm sim tuaj yeem ua rau lodging, yog li nws feem ntau raug tswj los ntawm metrophin. Lus Cim: Tsis tuaj yeem sib xyaw nrog cov tshuaj alkaline, tab sis tuaj yeem sib xyaw nrog cov kua qaub, cov chiv tsis muaj zog thiab cov tshuaj tua kab, thiab sib xyaw nrog urea kom nce qhov ntau lawm.
2. Lub sijhawm txau yog ua ntej 10:00 sawv ntxov thiab tom qab 3:00 tav su, yog tias los nag tsis pub dhau 4 teev tom qab txau, yuav tsum tau txau dua.
3. Qhov concentration ntawm cov khoom no siab heev, thov npaj raws li qhov ntau npaum li cas. Yog tias qhov concentration siab dhau, ceg, dawb yuav tshwm sim kom txog thaum deformed lossis qhuav, thiab cov nyhuv tsis pom tseeb yog tias qhov concentration qis dhau. Tus nqi ntawm cov kua siv rau cov zaub nplooj sib txawv nrog qhov loj me thiab qhov ceev ntawm cov nroj tsuag qoob loo. Feem ntau, tus nqi ntawm cov kua siv rau ib mu tsis tsawg dua 50 kg.
4. Cov kua dej ntawm gibberellin yooj yim rau decompose thiab yuav tsum tsis txhob khaws cia rau lub sijhawm ntev.
5. Kev siv ntawmgibberellintsuas yog ua lub luag haujlwm zoo nyob rau hauv qhov xwm txheej ntawm cov chiv thiab dej, thiab tsis tuaj yeem hloov cov chiv.
