Qhov sib txawv tseem ceeb ntawm imbricate thiab twisted aestivation yog tias imbricate aestivation yog hom aestivation qhov twg cov npoo ntawm appendages sib tshooj nrog ib leeg tab sis tsis nyob rau hauv ib qho kev taw qhia, thaum twisted aestivation yog hom aestivation qhov twg cov npoo ntawm appendages sib tshooj nrog ib leeg hauv ib qho kev taw qhia.
Aestivation piav qhia txog qhov chaw ntawm lub paj (appendages lossis perianth) hauv paj paj. Technically, nws yog lub koom haum ntawm calyx (sepals) thiab corolla (petals) txheeb ze rau ib leeg hauv paj paj. Calyx thiab corolla yog sau ua ke hu ua perianth. Aestivation yog qee zaum hu ua prefoliation. Yog li ntawd, imbricate thiab twisted aestivation yog ob hom aestivations hauv paj.
Ibricate Aestivation yog dab tsi?
Ibricate aestivation yog hom aestivation qhov twg cov npoo ntawm appendages sib tshooj nrog ib leeg tab sis tsis nyob hauv ib qho kev coj ua. Nyob rau hauv hom aestivation no, lub sab nrauv whorl los yog lub perianth (xws li petals thiab sepals) sib tshooj nrog ib leeg nyob rau hauv ib txoj kev uas ob peb petals nyob rau hauv tag nrho, thiab ib txhia yog tag nrho sab nraum. Nyob rau hauv no hom ntawm aestivation, muaj ib tug irregular overlapping ntawm petals nrog ib leeg. Yog li ntawd, qhov sib tshooj ntawm calyx (sepals) los yog corolla (petals) nyob rau hauv imbricate aestivation yog tsis tshwj xeeb. Qhov kev sib tshooj no tsis tshwm sim hauv ib txoj haujlwm tshwj xeeb.
Daim duab 01: Imbricate Aestivation
Tsis tas li ntawd, muaj ob hom imbricate aestivation: ascending imbricate thiab descending imbricate. Nyob rau hauv ascending aestivation, posterior petal yog innermost. Piv txwv ntawm hom imbricate aestivation tuaj yeem pom hauv Cassia, Bauhinia, thiab kub mohr. Nyob rau hauv descending imbricate aestivation, ntawm qhov tod tes, lub anterior petal yog innermost thaum lub posterior petal yog sab nraud. Piv txwv ntawm hom imbricate aestivation tuaj yeem pom hauv cov txiv laum huab xeeb. Quincuncial aestivation yog kev hloov kho ntawm imbricate aestivation uas tuaj yeem pom hauv Murraya thiab Ranunculus.
Twisted Aestivation yog dab tsi?
Twisted aestivation yog ib hom aestivation qhov twg cov npoo ntawm appendages sib tshooj nrog ib leeg hauv ib qho kev taw qhia. Nws tseem hu ua contorted los yog convolute aestivation. Nyob rau hauv hom aestivation no, lub sepals los yog petals yog teem nyob rau hauv xws li ib tug txoj kev uas ib tug ntug overlaps nrog rau tom ntej no ntug sab hauv.
Daim duab 02: Hom Aestivation
Nyob rau hauv twisted aestivation, ib tug paj ntaub paj ntaub overlaps ntawm tus tom ntej, thiab lwm yam paj ntaub paj ntaub overlaps ntawm tus tom ntej. Yog li ntawd, lawv niaj hnub sib tshooj nrog cov neeg nyob sib ze ntawm ib sab. Tsis tas li ntawd, qhov sib tshooj tshwm sim hauv ib txoj haujlwm tshwj xeeb. Cov piv txwv nrov yog paj ntawm Hibiscus, okra, thiab paj rwb.
Dab tsi yog qhov zoo sib xws ntawm Imbricate thiab Twisted Aestivation?
- Ibricate thiab twisted aestivation yog ob hom aestivations hauv paj.
- Ob hom yog ua raws li qhov chaw ntawm lub paj (appendages lossis perianth) hauv lub paj paj.
- Cov hom aestivations tuaj yeem siv los sib txawv ntawm cov paj ntawm cov nroj tsuag.
- Ob hom aestivations piav qhia txog kev npaj ntawm cov paj thiab sepals (perianth) hauv paj paj ua ntej tawg.
Qhov txawv ntawm Imbricate thiab Twisted Aestivation yog dab tsi?
Imbricate aestivation yog hom aestivation qhov twg cov npoo ntawm appendages sib tshooj nrog ib leeg tab sis tsis nyob rau hauv ib qho kev taw qhia, thaum twisted aestivation yog ib hom aestivation qhov twg cov npoo ntawm appendages overlap nrog ib leeg nyob rau hauv ib qho kev taw qhia. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm imbricate thiab twisted aestivation. Tsis tas li ntawd, lwm qhov sib txawv tseem ceeb ntawm imbricate thiab twisted aestivation yog qhov sib tshooj ntawm calyx (sepals) los yog corolla (petals) nyob rau hauv imbricate aestivation yog tsis tshwj xeeb, thaum lub overlapping ntawm calyx (sepals) los yog corolla (petals) nyob rau hauv twisted aestivation. yog tshwj xeeb.
Cov infographic hauv qab no qhia txog qhov sib txawv ntawm imbricate thiab twisted aestivation nyob rau hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Imbricate vs Twisted Aestivation
Aestivation hauv cov nroj tsuag tuaj yeem piav qhia raws li kev teeb tsa ntawm cov paj thiab sepals (perianth) hauv paj paj ua ntej tawg. Nws yog ib qho ntawm cov laj thawj uas ib tus tuaj yeem faib cov paj. Imbricate thiab twisted aestivation yog ob hom aestivation hauv paj. Imbricate aestivation yog hom aestivation qhov twg cov npoo ntawm cov appendages sib tshooj nrog ib leeg tab sis tsis nyob hauv ib qho kev coj ua. Twisted aestivation yog ib hom aestivation qhov twg cov npoo ntawm appendages sib tshooj nrog ib leeg nyob rau hauv ib qho kev taw qhia. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm imbricate thiab twisted aestivation.
