Yuav ua li cas paub qhov txawv ntawm rhizome los ntawm lub hauv paus? Peb paub tseeb tias yog koj nug cov lus nug zoo li no, ntau tus yuav xav tsis thoob, vim lawv ntseeg tias qhov no yog ib qho thiab tib yam. Tab sis hauv paus thiab rhizome yog cov ntsiab lus sib txawv kiag li. Vim li cas? Wb sib paub ua ke.
Kev hloov pauv hloov pauv
Tseem av saum toj no ntawm tsob ntoo hu ua tua. Nws muaj ob ntu: qia thiab nplooj. Cov nroj tsuag hauv nruab nrog cev ua haujlwm rau huab cua khoom noj khoom haus, kev sib pauv roj thiab vegetative reproduction. Tab sis nyob rau hauv tej yam kev mob no tsis txaus. Yog li ntawd, muaj kev hloov kho ntawm ntau yam kabmob ntawm cov nroj tsuag, nrog rau tua. Rhizomes yog ib qho ntawm lawv. Kev hloov kho ntawm qhov dav dav ntawm cov nroj tsuag kuj suav nrog qos yaj ywm thiab Jerusalem artichoke tuber, tulip thiab qej qij, strawberry whiskers thiab txiv hmab txiv ntoo tendrils. Tag nrho lawv ua haujlwm ntxiv. Piv txwv li, nrog kev pab los ntawm tendrils, txiv hmab txiv ntoo yog txuas nrog kev txhawb nqa, uas tso cai rau lawv coj qhov chaw zoo tshaj plaws rau cov txheej txheem ntawm photosynthesis. Tab sis nyob rau hauv lub teeb thiab hauv av, dej nrog cov as-ham yog khaws cia, uas tso cai rau cov nroj tsuag kom yooj yim ciaj sia lub sij hawm tsis zoo. Nrog kev pab los ntawm mustache, strawberries reproduce vegetatively, zoo li qos yaj ywm.nrog lawv cov kev hloov kho hauv av - tubers.
Rhizome structure
Rhizome, ua kev hloov kho hauv av ntawm kev tua, muaj tag nrho cov yam ntxwv ntawm nws cov qauv. Tab sis lawv tau hloov kho me ntsis. Rhizomes yog ib tug creeping qia nrog elongated internodes, nyob rau hauv uas tag nrho cov khoom tsim nyog rau cov nroj tsuag yog khaws cia. Bundles ntawm adventitious keeb kwm tawm ntawm nws. Thiab nyob rau saum npoo ntawm lub ntiaj teb, nplooj yog pom uas loj hlob los ntawm cov nodes ntawm ib tug elongated tua. Lawv yog cov yooj yim. Lawv nplooj nplooj yog nqaim, feem ntau nrog rau qhov sib npaug.
How to tell a rhizome from a root
Raws li koj tuaj yeem pom, hauv cov qauv ntawm cov rhizome koj tuaj yeem pom tag nrho cov ntsiab lus ntawm kev tua: ib qho elongated qia, los ntawm cov hauv paus hniav, pob, buds thiab nplooj ntev. Nws tsuas yog underground. Hauv paus thiab rhizome feem ntau tsis meej pem. Tab sis lawv qhov zoo sib xws tsuas yog nyob rau hauv lub npe. Tom qab tag nrho, lub hauv paus yog lub hauv paus ntawm cov nroj tsuag. Nws loj hlob ntawm kev khiav. Ntawm nws koj yuav tsis pom muaj buds lossis nplooj. Yog li ntawd, ib txwm, nws tsis muaj chloroplasts thiab tsis muaj peev xwm ntawm photosynthesis. Lub cev no anchors cov nroj tsuag nyob rau hauv cov av thiab muab cov ntxhia zaub mov. Thiab lub rhizome yog txoj kev khiav. Tsuas yog outwardly nws hloov dhau qhov kev lees paub thiab nyob hauv av. Cov hauv paus hniav uas nyob rau ntawm nws yog ib txwm adventitious. Lawv loj hlob nyob rau hauv bunches. Lawv kev sib xyaw ua ke ua rau cov hauv paus hniav fibrous.
Cov nroj tsuag twg muaj rhizomes
Rhizomes yog kev hloov kho yam ntxwv ntawm ntau cov nroj tsuag. Feem ntau ntawm lawvyog ib tug tswv cuab ntawm chav kawm monocot. Muaj tseeb tiag, ntau tus neeg ua teb tau sim tshem tawm cov kab mob phem hu ua wheatgrass. Qhov no tsis yog ib qho yooj yim ua precisely vim muaj ib tug rhizome nyob rau hauv cov nroj tsuag no. Rub tawm cov nplooj thiab ib feem ntawm cov nroj tsuag hauv av, ib tus neeg tsis paub tias feem ntau nws tseem nyob hauv av. Los ntawm buds ntawm khaws cia ib feem ntawm tua, tshiab nplooj loj hlob dua. Yog li ntawd, cov nroj tsuag loj hlob dua. Cov rhizome muaj lily ntawm hav, mint, asparagus, peonies, irises, phloxes, gravel, blueberries. Cov txiaj ntsig ntawm cov nroj tsuag uas muaj cov kev hloov kho no yog dab tsi?
Rhizome Functions
Ua ntej ntawm tag nrho cov, rhizomes muab kev cog qoob loo ntawm cov nroj tsuag, ua kom muaj txiaj ntsig zoo. Piv txwv li, rau cog irises, nws tsis yog yuav tsum tau coj lawv loj ib feem ntawm tua nrog nplooj thiab paj. Nws yog txaus los siv ib tug me me rhizome keeb nrog buds thiab adventitious keeb kwm. Txij li thaum qhov kev hloov kho ntawm qhov tua yog nyob rau hauv av, nws muaj ib tug txhim khu kev qha vaj tse los ntawm tag nrho cov tsis zoo ib puag ncig tej yam kev mob. Nws tsis ntshai dej nag. Thaum tshav kub kub, tsuas yog nplooj yuav tuag. Tab sis qhov chaw hauv av, uas yog qhov ncaj qha tua ntawm cov nroj tsuag, yuav nyob twj ywm. Thaum cov xwm txheej zoo tshwm sim, nplooj ntsuab yuav loj hlob los ntawm buds dua. Rhizomes yog cov khoom muaj txiaj ntsig hauv av ntawm dej, ntxhia thiab organic tshuaj uas cov nroj tsuag tau tsim thaum lub sijhawm muaj dej txaus thiab photosynthesis. Vim qhov no feature tseem ceeb, tag nrho cov nroj tsuag nrogqhov kev hloov kho no yog perennial. Lawv qhov chaw nyob hauv av tseem siv tau txij thaum pib lub caij nplooj zeeg mus rau lub caij nplooj ntoo hlav vim yog cov khoom siv ntawm txhua yam khoom tsim nyog rau qhov no, uas yog nyob rau hauv qhov kev hloov kho no.
Yog li, lub rhizome yog ib qho kev hloov kho hauv av. Nws qhov chaw tseem ceeb yog elongated internodes, buds, nplooj yooj yim thiab adventitious keeb kwm. Lub rhizome ua haujlwm tseem ceeb, ua tsaug rau cov nroj tsuag tau yooj yim ua rau lub sijhawm tsis zoo nyob hauv av thiab kis tau sai. Qhov no yog kev cia dej nrog cov as-ham thiab kev siv cov noob qoob loo.
