Sezinso isitshalo kanye nezici zayo morphological

Chaza morphological isakhiwo izinso isitshalo lilula. Vegetable izinso siqukethe stem embryonic, amahlamvu nezimbali. Vegetative efihlekile zihlukaniswa izinhlobo ezimbili: ukukhula (vegetative) kanye imbali (okuzala). Vegetative efihlekile simila siqukethe leaf. Uma sibheka ukwakheka kwazo okuzala ihlanganisa iziqalo of izimbali kanye inflorescences. Bud - imbali efihlekile, okuyinto has a imbali eyodwa. Izinso ukuthi kukhona kanyekanye ethulwa nakhululwa ezifundisweni zokucathula amahlamvu nezimbali, ngokuthi autonomic-okuzala, okusho elixutshwe.

Ngo okhulayo iphuzu kwakhiwa leaf umklamo, okuyinto zitholakala phezulu. Ngenxa yokuthi ingane yakho ikhula Ukuboshelwa, kuya phezulu, basuke eligoqiwe, kuka ngenxa ukubukeka isikhala ezimanzi ngaphakathi izinso. Ngakho izitshalo ihlumela ivikela uqobo kusuka iphele ukuphuma futhi umonakalo. Phakathi ukuqhakaza of efihlekile amaqabunga stem sishukumiseleka futhi waqonda, ngenxa ngokuyinhloko ukukhula okunamandla internodes stem.

Njengomthetho, lesi sitshalo has a brown ihlumela, umbala grey noma ensundu. Izinso yezinye izitshalo bok, ikakhulukazi labo ezikhula kahle ezindaweni ezibandayo e, embozwe izikali (amahlamvu modified), ebavikela amakhaza futhi ukulimala. Eminye imithi (ezifana birch, Poplar) isehlane izinto okhipha inhlaka ezithuthukisa ngalesi sivikelo. Lokhu ihlumela zalesi sihlahla eyaziwa ngokuthi yangasese noma livikelwe. Ngakho, isitshalo efihlekile, akudingeki izikali, eyaziwa ngokuthi olungaphephile noma uhamba-ze. fuzz abajonqile ukuthi ihlanganisa emzimbeni idatha kusuka ngaphandle, iyindlela ezingeziwe ebavikela ezahlukahlukene ezingezinhle.

Ezinye izitshalo herbaceous (kakolweni utshani, lily we esigodini) kuthiwa overwintering efihlekile, okuyinto zitholakala amahlumela komhlaba, bakwazi futhi atholakala engxenyeni engezansi amahlumela zasemoyeni eduze emhlabathini. Yingenxa ukubekwa esinjalo, izitshalo iveze imiqumbe lula angabacwasi ukuba sibhekane ngokuphumelelayo lokushisa ekushintshashintsheni. Ezinye izinhlobo zawo (isib cactus) babe izici ngazinye Ukuklanywa komzimba. Sezinso cactus ebizwa ngokuthi areola, zenziwa kusukela izikali Ushintshe - izinaliti ukuthi ukukhonza umsebenzi zokuzivikela.

Banikezwe indawo izinso esiqwini, bahlukene zibe ezilingene apical. Sezinso ekupheleni ukuthwebula ngokuthi lingasetshenziswa esigungwini (apical), ngenxa yokuthi uye wenziwa ukukhula stem. lateral efihlekile yakha uhlelo of amahlumela. Lateral efihlekile isitshalo okuthiwa axillary, uma itholakala ku axils ihlamvu. Vnepazushnymi (adventitious noma isandiso) izinso yilezo ezibekwe ezingxenyeni ezahlukene stem kuhlanganise izimpande.

Izinso kuthiwa kule axils amaqabunga zingafakwa bengabantu ngabanye emaqenjini. Kufanele kuqashelwe ukuthi kwasendaweni izinso ku axils amaqabunga kubaluleke kakhulu begazi. Coversheet ivikela izinso ekulimaleni mechanical, futhi ngenkuthalo iqhaza ekuhlinzekeni izakhi izinso.

Nge adventitious efihlekile eyenziwa esiphelweni vegetative. phindaphinda Ngakho ukhula ukwakha izitshalo (sonchus, e-aspen). Ziyini lezi amaswidi? Kalula nje, yingoba Kuphendula ukuthi ukuthuthukisa kusuka efihlekile adventitious phezu izimpande. Vnepazushnye efihlekile amaqabunga izitshalo ukuthuthukisa kakhulu kuyaqabukela. Njengoba isibonelo, kalanchoe. yezinso zayo ngokushesha ukukhiqiza amahlumela amancane obujwayelekile nge izimpande adventitious.

Ngokuba iningi Ezikhula iminyaka eminingi, izihlahla kanye izihlahla ejwayelekile efihlekile ithule ukuthi angahlala yokuzamazama isikhathi eside. Abakwazi uyoshintshwa eminyakeni ku amahlumela, kodwa kukhona okuyizici ezinomthelela ekuthuthukisweni efihlekile ithule (isib, ukufa esiqwini). A indima ebalulekile udlalwa ithule efihlekile ukuphila ehlathini. Ngenxa yentuthuko yabo akhiwa indodakazi iziqu, ogama Ubukhulu kukhona izikhathi eziningana mkhulu kunezinhliziyo ububanzi umgqomo umzali. Manje uyazi ukuthi izitshalo izinso futhi yini isebenta ke wenza.
