Qhov Tseem Ceeb Qhov Sib Txawv - Kev Loj Hlob vs Spore Formation
Kev cog qoob loo thiab kev tsim cov kab mob yog ob hom kev yug me nyuam hauv cov nroj tsuag. Vegetative propagation yog kev loj hlob los yog kev loj hlob ntawm cov nroj tsuag tshiab los ntawm ib feem los yog propagule. Spore tsim yog ib txoj kev uas cov neeg tshiab raug tsim los ntawm spores; me me spherical spores yog tsim thiab tso tawm rau hauv huab cua (ib puag ncig) los ntawm cov kab mob. Thaum cov spores no tau tso rau ntawm lub substrate tsim nyog, lawv germinate thiab loj hlob mus rau hauv cov neeg tshiab. Qhov sib txawv tseem ceeb ntawm kev cog qoob loo thiab kev tsim cov spores yog tias cov nroj tsuag propagation yog nqa tawm los ntawm cov nroj tsuag ntawm cov niam txiv thaum tsim spore yog ua los ntawm spores tsim los ntawm niam txiv.
Kev cog qoob loo yog dab tsi?
Kev cog qoob loo yog hom kev yug me nyuam ntawm cov nroj tsuag. Muaj ntau hom vegetative propagation units koom nrog hauv vegetative propagation. Lawv suav nrog cov neeg khiav dej num, corms, tubers, qhov muag teev, rhizomes, suckers, offsets, thiab lwm yam. Cov chav no muaj peev xwm tsim tau rau hauv cov nroj tsuag tshiab. Lawv kuj hu ua vegetative propagules. Yog tias muaj cov vegetative propagules, cov nroj tsuag tuaj yeem tsim cov nroj tsuag tshiab, yam tsis muaj noob los yog spores. Vegetative propagation tshwm sim ib txwm zoo li artificially.
Txoj vegetative propagation yog siv los ntawm cov neeg ua teb thiab cov neeg ua liaj ua teb los tsim kev lag luam nthuav tawm. Lawv siv ntau txoj kev ntawm kev cog qoob loo. Cov kab lis kev cai, grafting, budding, layering, thiab cuttings yog ob peb txoj kev siv nyob rau hauv dag vegetative propagation. Feem ntau hom vegetative propagation yog ua los ntawm qia cuttings. Nws yog ib txoj kev yooj yim ntawm propagating nroj tsuag. Ib daim ntawm cov niam txiv cog yog muab tshem tawm thiab muab tso rau ntawm ib tug haum substrate kom loj hlob mus rau hauv ib tug tshiab nroj tsuag. Grafting yog lwm txoj kev nrov ntawm kev cog qoob loo. Grafting yog ua los ntawm kev koom nrog ib lub qia los yog bud mus rau lub qia ntawm cov nroj tsuag paub tab uas muaj cov hauv paus hniav.
Kev yug me nyuam ua rau cov nroj tsuag tshiab uas zoo ib yam li cov niam txiv cog. Yog li ntawd, cov noob caj noob ces ntawm cov nroj tsuag raug txo, thiab lawv txhua tus sib tw rau tib yam khoom noj khoom haus hauv av. Qhov no yog ib qho kev tsis zoo ntawm kev yug me nyuam.

Spore Formation yog dab tsi?
Spore tsim yog ib hom kev yug me nyuam tsis zoo uas pom hauv cov kab mob xws li cov nroj tsuag qis, fungi, thiab algae. Cov kab mob niam txiv tsim cov spores uas thaum kawg tsim cov kab mob tshiab zoo ib yam li niam txiv. Cov txheej txheem ntawm sporogenesis yog hu ua sporogenesis. Haploid spores muab nce mus rau gametophyte tiam hauv cov nroj tsuag. Lawv tsis yog gametes tsim los rau kev sib deev. Hauv cov kab mob fungi thiab qee cov algae, qhov tseeb asexual spores yog tsim los ua ib hom kev yug me nyuam asexual. Cov spores no yog tsim los ntawm mitosis, thiab thaum lawv loj hlob, lawv loj hlob mus rau cov neeg tshiab.
Cov spores no me me thiab tsis hnyav thiab muaj cov phab ntsa tuab los tiv thaiv ib puag ncig hnyav. Feem ntau ntawm cov spores yog dispersal los ntawm cua. Ib tug loj tus naj npawb ntawm spores yog tsim los ntawm ib tug kab mob nyob rau hauv ib lub sij hawm.

Summary – Vegetative Propagation vs Spore Formation
Kev cog qoob loo thiab kev tsim cov kab mob yog ob hom kev yug me nyuam asexual uas pom los ntawm cov kab mob. Lub ntsiab sib txawv ntawm vegetative reproduction thiab spore tsim yog hais tias vegetative reproduction yog ua tiav siv ib tug vegetative ib feem xws li khiav, corm, tuber, noob los yog qia ntawm cov nroj tsuag thaum lub sij hawm tsim spores yog tsuas yog ua los ntawm haploid spores. Ob txoj kev tsim cov tib neeg tshiab yam tsis muaj kev koom nrog ob niam txiv thiab fertilization.
