Asexual kev yug me nyuam tsim cov neeg uas muaj caj ces zoo ib yam li niam txiv cog . Cov hauv paus hniav xws li corms, qia tubers, rhizomes, thiab stolon undergo kev yug me nyuam.
Ib yam li ntawd, cov nroj tsuag twg loj hlob los ntawm cov hauv paus hniav?
Cov hauv paus hniav xws li corms, qia tubers, rhizomes, thiab stolon undergo vegetative kev yug me nyuam . Ib txhia nroj tsuag tuaj yeem tsim cov noob yam tsis muaj fertilization ntawm apomixis qhov twg ovule lossis zes qe menyuam ua rau cov noob tshiab.
Kuj Paub, yog dab tsi yog root vegetative propagation? Ntuj vegetative propagation yog ib txoj hauv kev uas zaub lub cev xws li keeb kwm , stems thiab nplooj tsim ib tsob nroj tshiab.
Kuj Paub, muaj qee yam piv txwv ntawm kev nthuav tawm vegetative?
Cov ntau hom vegetative propagation yog piv txwv ntawm asexual reproduction. Cov xeeb tus cov nroj tsuag yog clones ntawm tus thawj cov nroj tsuag txij li tsis muaj kev sib xyaw ntawm DNA tshwm sim. Cov feem ntau hom ntawm vegetative propagation yog grafting, txiav, layering, tuber, noob los yog stolon tsim, suckering thiab kab lis kev cai.
Yuav ua li cas cov nroj tsuag reproduce vegetatively?
Ntuj zaub propagation tshwm sim thaum lub axillary bud hlob mus rau hauv ib tug lateral tua thiab tsim nws tus kheej cov hauv paus hniav (tseem hu ua adventitious keeb kwm). Nroj tsuag cov qauv tso cai rau ntuj zaub propagation muaj xws li qhov muag teev, rhizomes, stolons thiab tubers.
Pom zoo:
Cov kab mob dab tsi nyob hauv cov hauv paus hniav ntawm cov nroj tsuag?
Cov kab mob hauv paus muaj txiaj ntsig txhawb cov nroj tsuag kev loj hlob thiab muab kev tiv thaiv los ntawm cov kab mob. Lawv feem ntau yog rhizobacteria uas yog Proteobacteria thiab Firmicutes, nrog ntau yam piv txwv los ntawm Pseudomonas thiab Bacillus genera. Rhizobium hom colonize legume keeb kwm tsim cov qauv nodule
Cov nroj tsuag twg hu ua terrestrial nroj tsuag?
Ib tsob ntoo hauv av yog cov nroj tsuag uas loj hlob ntawm, hauv, lossis los ntawm av. Lwm hom nroj tsuag yog dej (nyob hauv dej), epiphytic (nyob ntawm tsob ntoo) thiab lithophytic (nyob hauv lossis hauv pob zeb)
Dab tsi yog qhov cuam tshuam ntawm cov kab mob nroj tsuag uas rhuav tshem tag nrho cov chloroplasts hauv cov nroj tsuag?
Hauv cov xwm txheej ntxhov siab xws li drought thiab kub siab, cov nroj tsuag ntawm tes chloroplasts tuaj yeem ua rau puas tsuaj thiab tsim cov kab mob tsis zoo rau cov pa oxygen (ROS)
Lub luag hauj lwm ntawm cov nroj tsuag kev loj hlob regulators nyob rau hauv cov nroj tsuag kab lis kev cai yog dab tsi?
Hauv cov nroj tsuag kab lis kev cai, kev loj hlob regulator muaj lub luag haujlwm tseem ceeb xws li tswj cov hauv paus thiab tua kev loj hlob hauv cov nroj tsuag tsim thiab callus induction. Cytokinin thiab auxin yog ob txoj kev loj hlob zoo
Cov nroj tsuag twg muaj cov hauv paus hniav?
Aerial keeb kwm yog adventitious keeb kwm. Lwm cov nroj tsuag nrog cov hauv paus hniav muaj xws li cov ntoo ntawm cov hav zoov hav zoov hav zoov hav zoov, xws li. mangroves, banyan ntoo, Metrosideros robusta (rātā) thiab M. excelsa (pōhutukawa), thiab qee yam vines xws li Hedera helix (Common Ivy) thiab Toxicodendron radicans (poison ivy)
