+6 misiyano pakati pemiti nemichindwe

Kwenguva refu kwazvo, uye nanhasi, zvinokwanisika kuwana mabhuku umo zvinonzi miti yemichindwe miti. Ichi chimwe chinhu chinogona kutitsausa, sezvo marudzi ese ezvirimwa aine maitiro akasiyana, uye mashoma akafanana kupfuura mabasa aanoita kuti arambe ari mupenyu.

Ndicho chikonzero munyaya ino ndichatsanangura ndeupi musiyano pakati pemiti nemichindwe, nemifananidzo, kuitira kuti iwe ugozvitarisa iwe pachako. Saka kana uchida kuziva gara neni.

Monocotyledonous, dicotyledonous… Mazwi aya anorevei? Naizvo. Mhodzi padzinomera, dzinogona kumera kapepa kekutanga kana maviri. Aya mashizha madiki anozivikanwa nezita rekuti cotyledon, uye ndivo vachadyisa mbeu kusvikira mashizha echokwadi okutanga atungira.

Kana iri michindwe, cotyledon imwe chete inomera, iyo yakasvibira uye yakareba muzviitiko zvakawanda. Kutaura zvazviri, zviri nyore kuivhiringa nelawn grass.

Miti, kune rumwe rutivi, ine cotyledons maviri. Asi chinhu hachisi nyore seizvi. Inowedzera zvakanyanya:

Phoenix uye Washingtonia palm miti.

Paunofunga nezvemakwenzi, zvirimwa zvidiki zvine madzinde egirinhi anotsemuka zvinouya mupfungwa nyore. Asi kune marudzi akawanda emishonga, uye mamwe anonyanya kushamisa ndeaya makuru, anozivikanwawo se megaphorbias, kusanganisira michindwe.

Izvi Ndiwo zvirimwa zvisingaperi (kureva kuti, vanorarama kwemakore akati wandei) zvinosvika kureba, mamita akawanda. Kuti ndikupe pfungwa, mhando dzemichindwe Cerylon quiniuense Inogona kusvika mamita makumi manomwe pakureba. Izvo zvinoshamisa uchifunga kuti ivo havagadziri trunk yechokwadi, izvo zvinondiunza ku...:

Kune michindwe midiki, mimwe mikuru,... Mimwe ine dzinde (inonzi stipe), uye vamwe -vadiki- havana. Kana vari avo vanorikudziridza, panguva yehuduku hwavo vanorebesa zvishoma nezvishoma, vachikora sezvavanobvisa mashizha matsva. Kana vangosvika pakureba kwavo, ndipo pavanopa chikamu chakanaka chesimba ravo kukura muhurefu.

Asi zvakadini kana vakatambura kukanganisa pakati pekorona yavo yemashizha? Kana izvo zvinokuvadza zvichibva kune yayo chete apical meristem, inonziwo nzvimbo yekukura kana gwara, zvapera. Kana chiri muchindwe chine madzinde akati wandei, zvinova mhedzisiro yeaxillary nhungirwa pazinde guru, chete dzinde rinenge rakuvadzwa rinofa.

Miti, kune chikamu chavo, ine lateral meristems uye cambium, nekuda kwainogona kupora kubva kumaronda.. Uye kana davi rikava risina basa, haungavi magumo emiti; asi kuzasi dzaibukira mashizha uye, nerombo rakanaka, matavi matsva.

Miti yemichindwe midzi inoyevedza. Kana tichitaura nezve adventitious tinoreva mamwe marudzi emidzi inomuka kubva panzvimbo imwe chete, iyo munyaya yemiti yemichindwe inharaunda yekunze yepakati cylinder umo midziyo mumudziyo kana stipe inobatana. Nokufamba kwemakore, zvingava zvakadaro kuti muchindwe unosvika pauwandu hwemidzi zvokuti bark rinotsemuka.

Kana huri kureba kwawo, kunotsamira zvikuru parudzi rwemichindwe uye kwairi kukura. Asi tichifunga kuti ivhu rakanyanya kana kushoma, uye kuti vane hunyoro uye kudya kwavanoda, vanogona kuita 15 metres kana kupfuura mumienzaniso yevakuru.

Midzi yemiti yakasiyana. Muzvirimwa izvi zvinowanzoita kusiyanisa mudzi mukuru kana wepivoting, iyo inokora zvishoma kupfuura mamwe, nemimwe midzi mitete zvikuru. Wokutanga ndiye ane basa rekumisa muti pasi, asi mamwe ndiwo anoenda kunotsvaka mvura. Zvakare, sezvo vaine cambium, iwo emamwe marudzi anogona kushandiswa kubatanidza.

Mashizha

: Pinnate palm leaf.

: Washingtonia ine mashizha emichindwe.

: Costapalmate shizha reSabal palm tree.

Mashizha, zvichida, chii chingakubatsira iwe zvakanyanya kuziva kana chaunoona chiri muchindwe kana muti. Uye ndizvo izvo zve michindwe inogona, kazhinji, yemhando nhatu: pinnate, costapalmate kana palmate.

Pinnate: ndeavo vane mapepa kana pinnate akabatanidzwa perpendicular kune rachis, iyo inowedzera petiole.
Palmada: ndidzo dzine chimiro chefani.
Costapalmada: aya anowanzo akatenderedzwa-oval mashizha, ari pakati pakati peaya maviri apfuura.

Ukuwo, iyo yemiti inogona kuva, zvichienderana nechimiro chavo:

Nyore: ndeaya ane nhengo yakasungirirwa pazinde kana bazi, uye anogona kunge aine muganho wese, wakadzikira kana mazino.
Musanganiswa: ndiwo iwo anoumbwa nemashizha maviri kana anopfuura anobuda kubva paaxis imwechete.
Bipinnaticomposite: iwo akafanana neaya akabatanidzwa, asi mapepa, panzvimbo yekukamura kamwe chete semukomboni, ita izvozvo kaviri.

Uye maererano negadziriro yako:

Alternate: ndidzo dzinomera kumativi ose ebazi.
Zvakapesana: ndezviya zvinomuka kubva panzvimbo imwechete yebazi, asi zvinokura zvakatarisana.
Whorled: ndeaya anomera mumapoka anopfuura maviri kubva panzvimbo imwe chete.
Radial: ndeavo vane chimiro chakafanana nechimiro chebhurashi.
Mumapoka: akafanana neaya apfuura, asi anomera pamagumo ematavi mapfupi mumapoka maviri kana anopfuura.

Uyewo, apo mashizha emimwe miti (kazhinji inodzikama deciduous) vanoshandura ruvara rwavo pane imwe nguva yegore, mashizha emichindwe anoramba akasvibira nguva dzose (kunze kwevamwe vakaita se Chambeyronia macrocarpa, izvo zvainoita kubvisa shizha dzvuku idzva, zvichida kuedza kurichengetedza kubva kune zvikara. Asi painokura, inoshanduka kuita girinhi.)

Flores

: Syagrus palm tree maruva

: Maruva emuti werudzi rwePrunus.

Maruva emiti yemichindwe akaunganidzwa mune mamwe kana mashoma branched inflorescences, nguva dzose. Izvi zvinogona kumera kubva pakati pemashizha, kana kubva kuguta guru (guta guru ndiro mubatanidzwa pakati pekorona uye stipe, iyo dzimwe mhando dzine, dzakadai seArchontophoenix genus). Aya maruva anogona kunge ari murume kana mukadzi, uye anoonekwa pamuti wemuchindwe mumwechete kana ari monoecious, kana mumhando dzakasiyana kana iri dioecious mhando.

Sekuda kuziva, zvinonakidza kuziva kuti kune hapaxantic miti yemichindwe; ndiko kuti, michindwe inotumbuka kamwe chete muupenyu hwayo, yobva yafa, seCorypha.

Kune rumwe rutivi, maruva emiti anogona kunge ari murume kana mukadzi, achionekwa mumuenzaniso mumwechete kana mune imwe yakasiyana, kunyange zvazvo anogonawo kuva hermaphroditic. (sezviya zvomuorivhi kana olea europaea) Maruva mazhinji emiti ane petals uye/kana sepals, uye ane akawanda akasiyana maumbirwo.

Sezvaunogona kuona, pane misiyano pakati pemichindwe nemiti. Zvimwe hazvionekwi, asi zvimwe zvinoshamisa.
