Qhov Tseem Ceeb Qhov txawv - Photoperiodism vs Phototropism

Nroj tsuag muaj lub peev xwm tshwj xeeb los teb rau lub teeb uas tso cai rau lawv hloov mus rau ib puag ncig thiab txhim kho lawv txoj kev loj hlob. Cov lus teb no tsis yog-photosynthesis ntsig txog thiab cov nroj tsuag tuaj yeem teb rau qhov sib txawv nthwv dej ntev ntawm lub teeb. Hnub ci yog qhov tseem ceeb rau cov noob germination hauv qee cov nroj tsuag. Cov noob no tsuas yog tawg thaum lawv tau txais ntau lub hnub ci. Hauv cov nroj tsuag, lub teeb pom kev los ntawm ib hom tshwj xeeb ntawm lub teeb pom kev zoo molecules hu ua photoreceptors. Lub photoreceptor muaj cov protein uas koom nrog lub teeb tshwj xeeb absorbing molecule hu ua chromophore. Thaum lub chromophore tau txais ib qho tshwj xeeb lub teeb stimulus thiab absorbs lub teeb, nws ua rau cov kev hloov nyob rau hauv cov qauv ntawm cov protein uas hloov nws txoj hauj lwm thiab ua rau pib ib tug signaling txoj kev. Nrog rau lub teeb stimulus, txoj kev taw qhia ua rau cov lus teb tshwj xeeb uas suav nrog kev hloov pauv ntawm cov noob qhia uas ua rau muaj kev hloov pauv hauv kev loj hlob thiab kev tsim cov tshuaj hormones. Phototropism yog ib qho kev taw qhia txog cov lus teb uas ua rau cov nroj tsuag teb rau ib qho kev txhawb zog ntawm lub teeb uas tso cai rau lawv loj hlob mus rau qhov chaw ntawm qhov stimulus los yog deb ntawm nws. Photoperiodism yog txheej txheem tswj hwm uas ua rau muaj kev tswj hwm ntawm kev loj hlob ntawm cov nroj tsuag tshwj xeeb hauv kev teb rau qhov ntev ntawm nruab hnub lossis hmo ntuj. Qhov no yog qhov sib txawv tseem ceeb ntawm photoperiodism thiab phototropism.

Photoperiodism yog dab tsi?

Photoperiodism yog ib txoj kev tswj hwm ntawm kev loj hlob ntawm lub cev nrog rau qhov ntev ntawm nruab hnub lossis hmo ntuj. Nws tshwm sim hauv cov nroj tsuag thiab tsiaj txhu. Nyob rau hauv cov nroj tsuag, ib tug ntev ntev ntawm ib hnub los yog hmo ntuj yog yuav tsum tau rau lawv mus paj thiab ces hloov mus rau theem ntawm kev loj hlob ntawm nws lub neej voj voog. Qhov ntev ntawm nruab hnub lossis hmo ntuj yog pom los ntawm ib hom tshwj xeeb ntawm photoreceptor protein hu ua phytochrome. Raws li qhov kev xav no, cov nroj tsuag muaj ob yam sib txawv: cov nroj tsuag hnub luv thiab cov nroj tsuag ntev ntev. Lub paj ntawm cov nroj tsuag hnub luv tshwm sim thaum hmo ntuj ntev tshaj qhov txheeb ze qhov pib ntawm lub sijhawm photoperiod. Hauv lwm lo lus, qhov tshwm sim no tshwm sim vim qhov poob ntawm hnub ntev hauv qab ib qho kev qhia tshwj xeeb. Rice yog ib qho piv txwv ntawm cov nroj tsuag hnub luv.

Daim duab 01: Hnub luv cog – Rice

Ntau hnub cog paj thaum hmo ntuj poob qis dua qhov pib ntawm lub sijhawm photoperiod. Qhov no txhais tau tias, ib hnub ntev cov nroj tsuag paj thaum hnub ntev nce siab tshaj qhov tseem ceeb theem pib. Cov nroj tsuag zoo li spinach thiab barley yog cov piv txwv ntawm cov nroj tsuag ntev hnub.

YPhototropism yog dab tsi?

Phototropism yog ib qho tseem ceeb hauv cov nroj tsuag uas tso cai rau lawv teb rau ib qho kev txhawb zog ntawm lub teeb. Cov lus teb rau qhov kev txhawb nqa no ua rau muaj kev cuam tshuam nrog cov molecules sib txawv uas tsim cov lus teb loj hlob ntawm lub teeb los yog deb ntawm nws. Kev loj hlob teb rau qhov chaw ntawm lub teeb yog hu ua zoo phototropism whilst cov lus teb deb ntawm nws yog hu ua tsis zoo phototropism. Nyob rau hauv ib tsob nroj, cov cheeb tsam saum toj no hauv av xws li tua pom zoo phototropism; Qhov no tso cai rau cov nroj tsuag ntsuab loj hlob mus rau qhov chaw ntawm lub teeb uas txhim kho cov txheej txheem ntawm photosynthesis. Cov hauv paus hniav ntawm cov nroj tsuag qhia tsis zoo phototropism uas ua rau lawv loj hlob deb ntawm lub teeb.

Daim duab 02: Phototropism

Yog tias cov nroj tsuag tshwj xeeb raug cuam tshuam los ntawm qhov ntxoov ntxoo ntawm cov nroj tsuag ib puag ncig thiab tau txais lub teeb pom kev tsawg, qhov zoo phototropism tso cai rau lawv sib tw nrog cov nroj tsuag nyob ib puag ncig thiab loj hlob ntawm lub teeb kom tau txais ib feem ntawm lub hnub ci. Phototropism yog tswj los ntawm ntau lub teeb liab molecules, feem ntau yog los ntawm cov nroj tsuag hormone Auxin. Cov txheej txheem no yog sib koom ua ke ncaj qha vim muaj qhov sib txawv ntawm Auxin distributions hauv cov nroj tsuag.

Dab tsi yog qhov zoo sib xws ntawm Photoperiodism thiab Phototropism?

  • Photoperiodism thiab phototropism teb rau lub zog ntawm lub teeb thiab muaj cov molecules rau kev nqus ntawm lub teeb thiab rau kev tswj hwm.
  • Ob txheej txheem yog tswj los ntawm cov tshuaj hormones.
  • Lawv sib koom ib qho kev txhawb nqa uas yog lub teeb.

Qhov txawv ntawm Photoperiodism thiab Phototropism yog dab tsi?

YPhotoperiodism vs Phototropism

Photoperiodism yog txoj cai ntawm cov nroj tsuag kev loj hlob nyob rau hauv teb rau ntev ntawm hnub los yog hmo ntuj. Phototropism yog kev loj hlob ntawm cov nroj tsuag raws li kev coj ntawm lub teeb.
Nyob teb
Qhov kev txhawb nqa ntawm photoperiodism yog qhov ntev ntawm nruab hnub lossis hmo ntuj. Kev taw qhia ntawm lub teeb yog qhov kev txhawb nqa ntawm phototropism.
cov tshuaj hormones
Paj yog induced los ntawm cytokinin thiab GA hauv photoperiodism. Phototropism yog tswj los ntawm auxin.

Summary – Photoperiodism vs Phototropism

Nroj tsuag teb rau qhov stimulus ntawm lub teeb. Cov lus teb txawv raws li qhov nthwv dej ntev ntawm lub teeb. Teb rau lub stimulus ntawm lub teeb yog ib tug uas tsis yog-photosynthetic txheej txheem. Phototropism yog qhov kev loj hlob ntawm cov nroj tsuag tshwj xeeb hauv kev teb rau cov kev taw qhia ntawm lub teeb. Kev tua ntawm cov nroj tsuag pom zoo phototropism thiab hauv paus ntawm cov nroj tsuag qhia tsis zoo phototropism. Photoperiodism yog cov kev cai ntawm kev ua paj thiab lwm yam kev loj hlob ntawm cov nroj tsuag nrog rau qhov ntev ntawm nruab hnub lossis hmo ntuj. Raws li kev tshawb xav photoperiodism, cov nroj tsuag muaj ob hom: cov nroj tsuag hnub luv thiab cov nroj tsuag ntev. Ntawm no, lub paj yog induced raws li qhov ntev ntawm hnub los yog hmo ntuj. Qhov no yog qhov txawv ntawm photoperiodism thiab phototropism. Txawm li cas los xij, ob qhov xwm txheej no sib koom ua ib qho kev txhawb siab, uas yog lub teeb, thiab teb raws li kev tswj hwm sib txawv xws li cov tshuaj hormones thiab photoreceptors.
