Impso zomera ndi zochititsa morphological

Fotokozani morphological Kapangidwe ka impso chomera wokongola yosavuta. Masamba impso tichipeza embryonic tsinde, masamba ndi maluwa. masamba Vegetative anawagawira mu mitundu iwiri: kukula (vegetative) ndi maluwa (zobereka). masamba Vegetative mmera tichipeza tsamba. Mu dongosolo zobereka zikuphatikizapo zoyamba za maluwa ndi inflorescences. Bud - ndi maluwa, amene ali duwa limodzi. Impso amene imodzi anapereka zoyamba za masamba ndi maluwa, wotchedwa autonomic-zobereka, mwachitsanzo osokonezeka.

Mu kukula mfundo anapanga tsamba mbalizo, zomwe zili oposa. Chifukwa chakuti akukulira omangidwa, pamwamba, iwo apangidwe, kuposa chifukwa maonekedwe a danga yonyowa mkati impso ndi. Motero zomera Mphukira amateteza wotuluka atayanika kunja ndi kuwonongeka. Pa ukufalikira wa masamba masamba tsinde ndi kuyendayenda ndi anaweramuka, chifukwa kwenikweni mbewuzi wa internodes tsinde la.

Monga ulamuliro, mbewu ali ndi Mphukira bulauni, imvi kapena zofiirira mtundu. Impso ena zomera zake, makamaka kukula mu nyengo yozizira, yokutidwa ndi mamba (kusinthidwa masamba), kuwateteza ku chisanu ndi kuvulala. Ena mitengo (monga birch, popula) olekanitsidwa zinthu utomoni wonunkhira kuti patsogolo chitetezo izi. Izi Mphukira ya zomera amadziwika zachinsinsi kapena kutetezedwa. Choncho, zomera masamba, mulibe mamba, lotchedwa mosadziteteza kapena wamaliseche. Wandiweyani fuzz okuta thupi deta kuchokera kunja, ndi njira zina za kuwateteza ku zosiyanasiyana zinthu chowawa.

Ena zomera herbaceous (tirigu udzu, kakombo wa mzigwa) ali overwintering masamba, imene ili mphukira mobisa, iwo akhoza kupezeka mu mmunsi mwa mphukira mlengalenga pafupi nthaka. Ndendende chifukwa Kusinthaku amenewa, zomera idzaphuka mwachilungamo zovuta kupirira kusinthasintha kutentha. Ena mitundu (mwachitsanzo nkhadze) Mbali munthu wa kapangidwe ka thupi. Impso nkhadze wotchedwa areola, iwo anapangidwa kuchokera mamba kusinthidwa - masingano kuti kutumikira ntchito ndi zoteteza.

Popeza malo a impso pa tsinde, iwo anawagawa lateral ndi apical. Impso pa mapeto a mphukira imatchedwa osachiritsika (apical), chifukwa izo ikuchitika kukula tsinde la. masamba lateral kupanga dongosolo la mphukira. Ofananira masamba mbewu wotchedwa axillary, ngati isanafalikire mu axils tsamba. Vnepazushnymi (adventitious kapena kutambasuka) impso ndi amene anayikidwa mu madera osiyana a tsinde kuphatikizapo mizu.

Impso ndi mu axils masamba akhoza adzaikidwa kuyambira pa aliyense payekha komanso mu magulu. Tikumbukenso kuti kutanthauzira a impso mu axils masamba ndi zofunika kwambiri kwachilengedwenso. Coversheet amateteza impso zisaonongeke makina, komanso nawo mwakhama ntchito yopereka chakudya impso.

Ndi masamba adventitious anagwira vegetative kafalitsidwe. Choncho kuchulukitsa udzu kupanga zomera (sonchus, Aspen). ndi suckers zimenezi? Mwachidule, akuwombera kuti kukhala ku masamba adventitious pa mizu. Vnepazushnye masamba pa masamba a zomera kukhala kawirikawiri. Mwachitsanzo, kalanchoe. impso yomweyo kutulutsa ang'ono-kakulidwe mphukira ndi mizu adventitious.

Pakuti ambiri perennials, zitsamba ndi mitengo lililonse matalala masamba kuti zikhale sanaidziŵe kwa nthawi yaitali. Iwo sangakhoze kusandulika kwa zaka mphukira, koma pali zinthu zomwe zimathandiza kuti pakhale masamba matalala (mwachitsanzo, imfa ya tsinde). A mbali yaikulu anagwira matalala masamba moyo chitsamba. Chifukwa chitukuko zimapangika mwana makungwa, amene miyeso ndi kangapo wamkulu kuposa awiri a kholo mbiya. Tsopano inu mukudziwa chimene zomera impso ndi zimene amatha kuchita izo amachita.
