Itsvo chirimwa chacho morphological zvinhu

Rondedzera morphological nemamiriro itsvo chirimwa akatsvinda nyore. Vegetable itsvo chinosanganisira hunde embryo, mashizha uye maruva. Vegetative Mafundo dzinoiswa kupinda mhando mbiri: kukura (vegetative) uye ruva (rokubereka). Vegetative Mafundo chirimwa rine shizha. In rokubereka mamiriro kunosanganisira zvokuvamba maruva uye inflorescences. Bud - ruva namabukira, ine chimwe ruva. Itsvo dziri panguva akapa zvokuvamba mashizha uye maruva, inonzi autonomic-rokubereka, kureva yakavhenganiswa.

In kukura pfungwa kuumbwa mashizha primordia, izvo dziri kumusoro. Nokuti vari kukura vanoiswa, kumusoro, ivo akapeta, pane nokuda nezve nyoro nzvimbo mukati itsvo. Saka miti chipande anodzivirira waibva kupwa panze uye kukuvadza. Panguva Blooming pakati nhungirwa kubva hunde mashizha vanokurudzirwa uye anombotwasanudza, zvakafanira zvikurukuru simba ikure hunde internodes.

Kazhinji, muti une nepfundo mashava, wachena kana shava ruvara. Itsvo zvimwe Woody zvinomera, kunyanya avo kuti vachikura inotonhora okunze, akafukidza zvikero (dzakachinjwa mashizha), ichivadzivirira nechando uye kukuvara. Vamwe Miti (akadai Birch, poplar) with anotsvedzerera anobuda pamiti nemakwenzi zvinhu kuti tiwedzere kudzivirira ichi. chipande ichi chirimwa inozivikanwa private kana kudzivirirwa. Saizvozvowo, chirimwa atwo, regai nechikero, rinozivikanwa kudzivirirwa kana kupfeka. Gobvu fuzz anofukidza muviri mashoko kubva kunze, chimwezve nzira ichivadzivirira kubva siyana nematambudziko zvinhu.

Vamwe miti herbaceous (gorosi uswa, ruva mumupata) vari overwintering namabukira, izvo iri pachivande mabukira, vanogona kuwanika yepazasi chikamu zvemuchadenga matavi pedyo ivhu. Chaizvo nokuti placement kwakadaro, zvinomera ichatungira kumbonyanya nyore kutsungirira tembiricha nokufamba. Dzimwe (eg mukonde) vane zviri nemamiriro muviri. Itsvo mukonde inonzi areola, zvinogadzirwa kubva dzakachinjwa nechiyero - tsono vanoshumira rwokudzivirira basa.

Akapiwa nzvimbo itsvo pamusoro hunde, vari rakakamurwa lateral uye apical. Itsvo pakupera nhungirwa anonzi chirwere (apical), nokuda voitakura kubva hunde kukura. lateral Mafundo vanoumba kwegadziriro awo. Lateral Mafundo chirimwa inonzi axillary, kana vemunyika mune shizha axils. Vnepazushnymi (adventitious kana kuwedzera) itsvo ndedziya inoiswa dzakasiyana-siyana hunde kusanganisira midzi.

Itsvo dziri muna axils nemashizha anogona kuiswa vaviri nomumwe uye mumapoka. Zvinofanira kucherechedzwa kuti localization etsvo iri axils nemashizha ane chaivo kukosha kukuru. Coversheet inodzivirira itsvo kubva zvokuimba kukuvadzwa, naicho achishingaira chikamu pakupa muviri itsvo.

With adventitious Mafundo vakatakura vegetative kupararira. Saka nekuwanza sora Anoumba miti (Sonchus, Aspen). Ndezvipi suckers izvi? Zvichitaurwa zviri nyore, zvinoita muchadya kuti kuva kubvira adventitious nhungirwa pamusoro kumidzi. Vnepazushnye nhungirwa pamusoro mashizha zvinomera kutanga kwazvo kashoma. Somuenzaniso, kalanchoe. Itsvo ake pakarepo pave duku kadikidiki awo pamwe adventitious midzi.

Nokuti vakawanda Perennial plants, nemiti yakabva kune dzimwe kwese wakaderera namabukira kuti ugare vanzika kwenguva refu kwenguva. Havagoni kushandurwa mumakore kupinda mabukira, asi pane zvinoita kuti pave wakaderera namabukira (semuenzaniso, rufu huru hunde). A rinokosha iri vaitambira wakaderera atwo mugwenzi upenyu. Nokuda kukura yavo kuumbwa mwanasikana hunde dzacho, vane kukura vari kanoverengeka kupfuura dhayamita nomubereki dhiramu. Zvino munoziva kuti itsvo zvinomera uye chii chinoshanda nayo anoita.
