Qhov sib txawv tseem ceeb ntawm vernalization thiab stratification yog vernalization yog ib qho kev kho mob uas yog siv los txhawb lub paj pib, thaum stratification yog ib qho kev kho mob uas yog siv los rhuav tshem cov noob dormancy.
Vernalization thiab stratification yog ob txoj hauv kev tseem ceeb cuam tshuam nrog cov nroj tsuag. Vernalization accelerates thaum ntxov flowering thaum stratification lov cov noob dormancy. Yog li, ob qho tib si ntawm cov txheej txheem zoo sib xws hauv kev ua liaj ua teb. Ntxiv mus, ob txoj kev koom nrog kev kho mob khaub thuas. Tsis tas li ntawd, stratification suav nrog cov xwm txheej sov thiab.
Vernalization yog dab tsi?
Vernalization yog ib qho kev kho mob uas tsis tshua muaj kub uas ua rau thiab txhawb kev tawg thaum ntxov hauv cov paj ntoo. Nyob rau hauv qhov tseeb, nws yog ib tug ntev, qis-kub kev kho mob ua rau cov nroj tsuag tua apex. Nws thiaj li shortens lub vegetative theem ntawm cov nroj tsuag thiab pab kom cov txiv hmab txiv ntoo teem thiab tawm los. Tsis tas li ntawd, vernalization txhim kho cov nroj tsuag tsis kam mus rau qhov txias txias. Yog li ntawd, lub caij ntuj no ntau yam tuaj yeem hloov mus rau hauv ntau yam caij nplooj ntoos hlav. Vernalization kuj ua rau cov nroj tsuag tsis kam mus rau cov kab mob fungal. Thiab, cov txheej txheem no yog ib qho ntawm cov kev xaiv zoo tshaj plaws nyob rau hauv horticulture thaum grafting ib tug vernalized tua apex nrog cov uas tsis yog-vernalized ib tug. Ntxiv mus, vernalization yog ib txoj hauv kev txhim kho qoob loo. Nws txo tus nqi ntawm cov qoob loo ntau lawm. Tsis tas li ntawd, nws pab txhawb kev loj hlob ntau dua ib qho qoob loo hauv tib lub caij.

Ntau yam cuam tshuam rau kev ua haujlwm ntawm cov txheej txheem vernalization. Cov no suav nrog hnub nyoog ntawm cov nroj tsuag, muaj cov pa oxygen, lub zog qhov chaw, lub sijhawm ntawm kev kho mob khaub thuas thiab dej. Yog li, raws li cov xwm txheej no, feem pua ntawm cov paj tuaj yeem hloov pauv. Gibberellin yog ib qho ntawm cov tshuaj hormones cog uas tuaj yeem hloov cov txheej txheem no.
Dab tsi yog Stratification?
Feem ntau, cov noob muaj lub sijhawm dormancy. Yog li, lawv xav tau tej yam kev mob rau germinate. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tau muab cov xwm txheej zoo kom tawg dormancy los txhawb cov noob germination. Stratification yog cov txheej txheem uas tuaj yeem rhuav tshem cov dormancy hauv cov noob thiab txhawb cov noob germination. Tsis tas li ntawd, cov txheej txheem no suav nrog ob qho tib si txias thiab sov stratification vim qee cov noob tawm los sov thiab ntub dej thaum lwm cov noob xav tau txias thiab ntub dej. Tsis tas li ntawd, qee qhov xav tau kev sib xyaw ua ke ntawm ob qho tib si txias thiab sov. Yog li, cov txheej txheem stratification txawv raws li hom noob.
Daim duab 02: Seed stratification
Cold stratification yog hom stratification uas cov noob raug rau ob qho tib si txias thiab noo. Ntawm qhov tod tes, sov stratification yuav tsum tau kub ntawm 15-20 ° C. Feem ntau, sov stratification tom qab txias stratification.
Dab tsi yog qhov zoo sib xws ntawm Vernalization thiab Stratification?
- Vernalization thiab stratification yog ob txoj kev koom tes hauv cov nroj tsuag.
- Ob txoj kev siv qhov txias txias.
- Lawv yog cov txheej txheem tseem ceeb hauv kev ua liaj ua teb.
Qhov txawv ntawm Vernalization thiab Stratification yog dab tsi?
Vernalization yog ib qho kev kho mob khaub thuas uas ua rau cov paj tawg thiab txo cov theem vegetative ntawm cov nroj tsuag. Lub caij no, stratification yog cov txheej txheem txias los yog sov so uas ua rau lub dormancy ntawm cov noob kom nce noob germination. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm vernalization thiab stratification.
Ntxiv mus, qhov sib txawv ntxiv ntawm vernalization thiab stratification yog tias vernalization tsuas yog kev kho mob khaub thuas xwb, thaum stratification muaj ob qho tib si txias thiab sov stratification.
Hauv qab infographic qhia txog qhov sib txawv ntawm vernalization thiab stratification.
Summary – Vernalization vs Stratification
Vernalization yog txheej txheem uas txhawb nqa paj thaum stratification yog txheej txheem uas txhawb cov noob germination los ntawm kev tawg cov noob dormancy. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm vernalization thiab stratification. Nyob rau hauv vernalization, tua apexes raug mus rau lub caij txias txias thaum, nyob rau hauv stratification, noob yog soaked nyob rau hauv dej rau ib los yog ob hnub.
