Izityalo, njengezilwanyana, zineeseli ezizodwa ezisebenza njengezithunywa. Nangona bezivelisa ngamanani amancinci, ngokungafaniyo nalawo aveliswa ngumzimba wethu umzekelo, zezo zilawula imeko yomzimba yezityalo, njengokukhula okanye ukudubula kweentyatyambo.

Wanna uyazi zithini ezi hormone zezityalo, Ikwabizwa ngokuba zii-phytohormones, kwaye yintoni umsebenzi abanayo? Kulungile masifike kuyo 🙂.

Yintoni phytohormones?

Phytohormones okanye iihormone zezityalo (phyto kuthetha isityalo ngesiLatin) Zizinto eziveliswa ziiseli zezihlunu zezityalo, njengamagqabi, amasebe kunye neengcambu. Eyona nto inomdla kukuba, nangona ziveliswa kwindawo ethile, zinokusebenza kwenye, oko kuthetha ukuba olu hlobo lolawulo "luhamba" ngaphakathi kwisityalo.

Zithini iihomoni zezityalo?

Iipytorhomonas ziveliswa kwiiseli zezityalo

Eziye zafunyanwa ukuza kuthi ga ngoku zezi:

  • I-asidi ye-AbscisicUthatha inxaxheba kuphuhliso kunye nokukhula kwesityalo, kunye nokulungelelanisa noxinzelelo.
  • IiAuxinsUkulawula ukukhula kwezityalo, kubangele ukwanda kweeseli.
  • IiCytokinins okanye ii-cytokinins: ukumisela ukukhula, ukoyisakala, ukufa- okucwangcisiweyo-, ukumelana nezitshabalalisi kunye nezifo, kunye nokunyamezelana nokuzikhusela kumarhamncwa.
  • I-Ethylene: yirhasi eveliswa kuwo onke amalungu esityalo, kwaye inemisebenzi emininzi: ukuntshula kwembewu, ukulawulwa kokukhula, ukuvuthwa kweziqhamo, ukukhuthaza ukubonakala kweeseli ezivuthiweyo ze-xylem kunye namagqabi kunye neentyatyambo. , kunye nokucaphukisa xa kukho imfuneko yokuphendula kathathu kwesityalo ukuze sikhule ngakumbi.
  • IGibberellins: iyangenelela ekuphazanyisweni kokulala kweembewu, kuphuhliso lwamahlumela kunye neziqhamo, kunye nolawulo lokukhula kwesiqu.
  • Brassinosteroids: Zibaluleke ngokukodwa kwizityalo ezincinci, kuba zithatha inxaxheba ekwandiseni, ekwahluleni nasekuhlukaniseni iiseli, into evumela ukuba zikhule.
