Qhov sib txawv tseem ceeb ntawm epicotyl thiab plumule yog tias epicotyl yog ib feem ntawm lub embryonic axis uas nyob saum cov ntsiab lus txuas ntawm cotyledons thaum plumule yog lub ntsis ntawm epicotyl uas ua rau muaj kev tua ntawm cov nroj tsuag tshiab.
Cov noob yog lub ovule ripened uas muaj lub embryo. Ntawm no, lub embryo yog cov nroj tsuag me me uas nyob hauv lub tsho loj. Tsis tas li ntawd, nws muaj ntau qhov chaw xws li cotyledons, plumule, radicle, epicotyl thiab hypocotyl. Ntawm cov no, epicotyl yog ib feem uas nyob saum cov ntsiab lus txuas ntawm cotyledons. Thiab, plume yog qhov ntxeev ntawm epicotyl thiab ua rau nce mus rau thawj nplooj tiag tiag ntawm cov nroj tsuag tshiab. Lub ntsiab tseem ceeb ntawm tsab xov xwm no yog qhov txawv ntawm epicotyl thiab plumule.
YEpicotyl yog dab tsi?
Epicotyl yog ib feem ntawm cov yub uas nyob saum cov ntsiab lus txuas ntawm cotyledons. Nws xaus ntawm lub plumule, uas yog lub ntsis ntawm lub epicotyl. Yog li ntawd, nws nyob hauv nruab nrab ntawm cotyledons thiab plumule.
Daim duab 01: Epicotyl
Epicotyl yog ib qho ntawm cov qauv tseem ceeb ntawm cov nroj tsuag thaum ntxov ntawm cov nroj tsuag lub neej. Qhov tseem ceeb, nws yog ib feem uas yog lub luag hauj lwm rau kev tawg ntawm cov av nyob rau hauv hypogeal germination.
Plumule yog dab tsi?
Plumule yog qhov ntxeev ntawm epicotyl thiab muab thawj nplooj ntawm tua. Yog li, plumule yog cov qauv uas ua rau muaj kev tua ntawm cov nroj tsuag tshiab. Tsis tas li ntawd, nws suav nrog meristem ib yam nkaus. Thaum cov cotyledons tau loj hlob saum av, kev loj hlob ntawm plumule tshwm sim.
Daim duab 02: Plumule
Nyob rau hauv epigeal germination, plumule hlob saum av ua ke nrog cov cotyledons. Tab sis, nyob rau hauv hypogeal germination, plumule tawm saum av ib leeg.
Dab tsi yog qhov zoo sib xws ntawm Epicotyl thiab Plumule?
- Ob qho tib si epicotyls thiab plumule yog saum toj ntawm qhov txuas ntawm cotyledons.
- Tsis tas li, ob qho tib si txhim kho thaum lub sijhawm cov noob germination.
- Dhau li, ob leeg tawm saum av saum npoo av.
Qhov txawv ntawm Epicotyl thiab Plumule yog dab tsi?
Epicotyl yog ib feem ntawm cov yub uas nyob saum cov cotyledons thaum plumule yog lub taub ntawm epicotyl uas ua rau muaj thawj nplooj tiag tiag ntawm cov nroj tsuag. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm epicotyl thiab plumule. Qhov tseeb, epicotyl nyob nruab nrab ntawm cotyledons thiab plumule thaum plumule nyob rau ntawm qhov kawg ntawm epicotyl.
Summary – Epicotyl vs Plumule
Epicotyl thiab plumule yog ob lub qauv tseem ceeb ntawm kev tsim embryo ntawm cov noob. Hauv kev xaus, lub epicotyl yog ib feem uas nyob nruab nrab ntawm cov cotyledons thiab plumule. Tab sis, plumule yog qhov ntxeev ntawm cov epicotyls thiab ua rau nce mus rau thawj nplooj tiag tiag ntawm cov nroj tsuag tshiab. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm epicotyls thiab plumule.
